Prometheus scrape timestamp. timestamp; prometheus; promql; Share.
Prometheus scrape timestamp I wanna know how to query metrics with timestamp that prometheus has. It would be better if you could use its scrape timestamp as your measurement of time too Yes, starting with v2. CreatedTimestamp , the parser doesn't return exemplars. TLDR #. So what you can do is implement your own Collector that produces snapshots with the scrape timestamp set. We recently added a flag to account for scrape jitter (--scrape. The metrics I am trying to scrape do not include timestamps. These metrics are exposed in a Prometheus-compatible format, typically over an HTTP or HTTPS endpoint. Metric Types. You might want to verify the timestamp format or ensure that the timestamp being generated is within an acceptable range. 4) we're seeing an issue where on our biggest instances every 30 minutes we have: - some counter updates are delayed, which looks like either scrapes are getting delayed - I only mention counters here because it's more visible on counters vs gauge, so Scraping is when Prometheus collects metrics from defined targets at regular intervals. a millisecond-precision The metric_version setting controls how telegraf translates prometheus format metrics to telegraf metrics. Metrics Path and Scheme: Prometheus The timestamp 1483228810000 converts back to January of this year. Assume we are going to create a metric my_metric that Every 5 minutes (scrape_interval) Prometheus will get the metrics from the given URL. timestamp(changes(up{job="prometheus"}[1h]) > 0) * 1000. You should use the following Prometheus config file in order to scrape metrics exported by prometheus_client at Telegraf: scrape_configs: - job_name: telegraf static You signed in with another tab or window. ratio Stack Overflow for Teams Where developers & technologists share private knowledge with coworkers; Advertising & Talent Reach devs & technologists worldwide about your product, service or employer brand; OverflowAI GenAI features for Teams; OverflowAPI Train & fine-tune LLMs; Labs The future of collective knowledge sharing; About the company as we are facing an issue when enabling the Prometheus port in Otel collector and adding istio scrape configs in Prometheus configs in default values yaml file 2024 A better approach is to send a heartbeat through the system: some dummy item that gets passed all the way through and includes the timestamp when it was inserted. This seems not a proper use case of Prometheus, but we just want to confirm. last_over_time( timestamp( changes( prometheus_http_requests_total{}[1m] ) > 0 )[1d:] ) will return timestamp of last change in metric prometheus_http_requests_total if it happened within last day. And what's more, we want to dig into metrics exporting methods. Improve this question. I am using kube state metrics for exporting node information however in the docs there isn't any mention of termination time, like there is with pods. rabbitmq_detailed_queue_head_message_timestamp: Timestamp of This receiver is a drop-in replacement for getting Prometheus to scrape your services. Closed fpetkovski opened this issue Jul 24, 2024 · 9 comments Feels like it would be expensive to detect whether the newest timestamp is identical to any other timestamps for that series in the same scrape. 6. Individual appenders // can decide what to do with metadata, but for Hi, :grinning:I am a student trying to figure out the scrape performance of Prometheus. In Prometheus 2. #export_timestamp = true Here's my prometheus config # my global config global: scrape_interval: 15s # Set the scrape interval to every 15 seconds. Another approach we're considering is to enable the feature flag which turns Prometheus into a remote write receiver (metrics written to /api/v1/write). The following query should return duration since the last increase of foo_total if the increase was no more than a day ago (see 1d in the query):. Set Appropriate Scrape Intervals: Choose a scrape interval based on the granularity you need. It is done on the second source_labels. --enable-feature=created-timestamp-zero set_timestamp: Optional. yaml --dry-run -oyaml > additional-scrape-configs. time() - max_over_time(timestamp(changes(foo_total[5m]) > 0)[1d:1m]) The accuracy of the returned duration is one minute (see 1m in the query). The configured scrape_timeout for a target. The We've started noticing that ever since we've upgrade Prometheus from v2. 4. I hope that prometheus can obtain multiple indicator values with different timestamps in one scrape. With metric_version = 1, the prometheus metric name becomes the telegraf metric name. You switched accounts on another tab or window. At any given time, how should Prometheus store multiple samples behind a Another use case: mtail 0. @vpedosyuk. 481Z caller=scrape. While exemplar timestamps are optional in Prometheus/Open Metrics exposition formats, the assumption is that a timestamp is assigned at scrape time in the same way a timestamp is assigned to the scrape sample. You might have some timeseries multiple times with different values, in which case I think the last one will be appended to tsdb, this doesn’t have to be “correct” one. For example a perfectly linearly increasing counter wouldn't have an identical increase from scrape to scrape anymore. 2 and run it for some time. PassMetadataInContext bool // Option to enable appending of scraped Metadata to the TSDB/other appenders. yml file. See these docs for more information. 3-PR21100 but since the code has been merged Actual timestamp vs Scrape timestamp in Prometheus time series. What did you do? I setup two prometheus services on two separate servers, one for client to scrap several targets(use agent mode) and another for remote write endpoint What did you expect to see? I This makes me think that what is happening is that when the sample is relabeled the sample timestamp is replaced with the current time and stored like that, then when the next scrape happens if the sample still has the previous timestamp Prometheus says that is out-of-order as the latest sample known by Prometheus has a greater timestamp than Time series are created in Mimir but we get "duplicate sample for timestamp" errors in the Prometheus log and the Mimir log. ), the configuration file defines everything related to scraping jobs and their instances, as well as which rule files to load. Next thing I would suggest trying is a manual curl request to make sure the endpoint itself is working, then if so you can focus on your library’s scrape config and try to figure out why it doesn’t match. Metrics expire if their timestamp is older that 60s. 2. The following example should comply with Prometheus API format: $ echo 'elapsed_scantime_count{Subject="DEV-Product-1"} 0. For Juniper devices, there are a number of things you can tune to improve scraping that should let you poll at a more reasonable rate without causing issues. if a timestamp is not added to metrics, Prometheus adds the scrape timestamp on the metrics scraped from /metrics endpoint on stackdriver_exporter. This lookbehind window is known as lookback delta and it can be configured with --query. Stack Overflow for Teams Where developers & technologists share private knowledge with coworkers; Advertising & Talent Reach devs & technologists worldwide about your product, service or employer brand; OverflowAI GenAI features for Teams; OverflowAPI Train & fine-tune LLMs; Labs The future of collective knowledge sharing; About the company Visit the blog Describe the bug otel-collector running with Prometheus receiver configured to scrape Prometheus-compatible endpoints discovered via kubernetes_sd_configs stops scraping when some service discovery Prometheus offers four core metric types to capture diverse system behaviors: Counters for tracking ever-increasing values, like the total number of exceptions thrown. Federate include timestamp of metrics. Multiple scrape_interval's in prometheus. grok_exporter is the component that enables Prometheus to scrape parsed metrics from arbitrary log files. 1: 466: April 12, 2021 How to understand relationship among scrape_interval, scrape_timeout Bug Report What did you do? Using /federate to scrape metrics on all prometheus instances . ratio: 0. This is a web server that exposes the timestamped Prometheus is configured via command-line flags and a configuration file. Now that our web server the current implementation of stackdriver_exporter doesn't add timestamp on metrics. 8. Thank you. 52. now in Prometheus metrics, someone know how do it? I tried to do it with gauge but the set predefined function seem to work only with double. Ask Question Asked 3 years, 5 months ago. lookback-delta command-line flag. I’m scraping from my k8s cluster running the prometheus operator. prom file such that Prometheus can scrape them. I have the global scrape interval set to 1h in the prometheus. Boolean for whether to set the Prometheus metric timestamp as the original Cloudwatch timestamp. For more elaborate overviews of scrape_configs: - job_name: self metrics_path: /metrics static_configs: - targets: - 'prometheus:9090' - job_name: ziti scheme: https metrics_path: /metrics honor_labels: true # Ziti supplies system labels for the edge routers, so we need to obey them honor_timestamps: true # Honor server timestamps instead of using the scrape timestamp for metrics Output structure. Optimizing scrape settings ensures efficient data collection and minimal load on the system. S. 0. In Prometheus, a target is an endpoint or service that Prometheus monitors by scraping metrics. We will explore how to use the Prometheus Java client Go to the Prometheus data directory and remove everything inside it: ls -lrt drwxr-xr-x 2 prometheus prometheus 6 Oct 20 2021 chunks_head -rw-r--r-- 1 prometheus prometheus 0 Oct 19 21:18 lock -rw-r--r-- 1 prometheus prometheus 20001 Oct 19 21:20 queries. For some metrics which are updated very infrequently (such as S3/BucketSize), Prometheus may refuse to Further findings, I increased scrape_interval of targets from 5s to 10s and it works. Write a custom exporter. But collector is unable to scrape endpoint. The timestamp value "1692630513175" seems to be incorrect or invalid, leading to the failure. Hence my guess to use set_timestamp: I would like to make a custom metric to store datetime. Like here – Prometheus cannot scrape two samples from the same series with different timestamps anymore #14503. I’m a beta, not like one of those pretty fighting fish, but like an early test version. Default is every 1 minute. timestamp-tolerance 49ms) serverA ran out of disk recently and had compactions fail as a result; # Default values for opentelemetry-collector. I’m running it into a few machines as part of my home lab setup, where I want to collect the logs of some docker containers. 3. This will parse the IP, timestamp, HTTP request details, response code, etc into Prometheus labels. Periodically the server scrapes the targets and store what is available at that time, with its scrape timestamp. The Prometheus Pushgateway allows you to push time series from short-lived service-level batch jobs to an intermediary job which Prometheus Collect metrics via the Prometheus client However, Prometheus does not scrape them, and outputs the following logs: My guess is that CloudWatch being located in Virginia, and our cloudwatch_exporter and Prometheus being in EU, there is a Timestamp difference preventing Prometheus to scrape these metrics. metrics information is stored with the timestamp at which it was recorded, alongside optional key-value pairs called labels. cAdvisor puts a timestamp on its metrics; it does this because it sources the data asynchronously so it doesn't want the Prometheus scrape timestamp. 0 such "duplicates" are no longer ignored. So there might be a relation between global scrape interval and per target scrape interval. io/scrape with the value 'true'. file /etc/prometheus/config/prometheus. Prometheus exporter - reading CSV file having data from the past day. 5k nodes, at least 3 endpoints on eac Expect exemplars for counters/histograms/summaries on first scrape when --enable-feature=exemplar-storage,created-timestamp-zero-ingestion. Adding a staleness marker just makes the series stop. It is done in the first source_labels. Prometheus values become telegraf field values. The timestamp Prometheus attaches to the scrape is the start of the scrape, which represents when Prometheus sees the data. Steps to reproduce Deploy monitoring with terraform-aws-observability-accelerator What did y Prometheus is configured via command-line flags and a configuration file. What is the minimum scrape_interval in Prometheus? 0. An “explicit timestamp” is an optional timestamp in the Prometheus metrics exposition format. This approach Rather than eliminate explicit timestamp support, I'd rather have prometheus provide an option to have multiple versions of the meric timeseries (one using the explicit business meaningful timestamp for charting and one using the scrape timestamp for use with alerting. drain-notification-queue-on-shutdown: true--alertmanager. Instead, what Prometheus attaches as a timestamp is the time when it scrapes the Pushgateway. It’s a little bit more complicated than that. Prometheus Monitoring System What does the timestamp field in text format record. I agree, that's far Instead, Prometheus assigns its own scrape start timestamp to all pulled samples. ) Our Use Cases: We have processes that calculate metrics from events. Existing metric: Prometheus supports templating in the annotations and labels of alerts, as well as in served console pages. It is also not advised to use timestamps in this way. yaml Then created the secret using the below command. nils March 2, 2022, 3:48pm 1. Also, the calculation extrapolates to the ends of the time range, allowing for missed scrapes or imperfect alignment of My goal is to observe a gauge indicator that changes over time with a custom timestamp. But I failed, so if anybody know how to do it, please leave a message. x, a timestamp with the perfect double-delta of zero consumes 1bit. Use file-based service discovery to discover scrape targets; Instrumenting a Go application; Enable Prometheus's dimensional data model to identify any given combination of labels for the same metric name. # Declare variables to be passed into your templates. kubectl create secret generic additional-scrape-configs --from-file=prometheus-additional. 5. It supports the full set of Prometheus configuration in scrape_config, including service discovery. 6. go:104 Failed to scrape Prometheus endpoint roidelapluie changed the title New metric: last_scrape_time_seconds New metric: scrape_timestamp_seconds Dec 15, 2017 brian-brazil added the component/scraping label Dec 15, 2017 Copy link Prometheus is essentially a time-series databases and, when it scrapes measurements from exporters, it records the value as a combination of its timestamp of the scrape and your label values. prometheus. active drwxr-xr-x 2 prometheus prometheus 66 Oct 19 21:18 wal HI Team, we have configure AWS distro open telemetry add-on and deployed collector config by adding aws managed prometheus endpoint to collector configuration with required service role as per document. 613Z The behavior of this function may change in future versions of Prometheus, including its removal from PromQL. x so we expect some non-compliant targets to require the fallback property being set until they are fixed. Actual timestamp vs PrometheusDuplicateTimestamps # Find the Prometheus Pod that concerns this. Here is what I did. However, one has blocks that take up significantly more data (~140GB vs 108GB). 1 to v1. In older versions, Prometheus already allowed setting the --scrape. The data model implements read-only snapshots that are produced when the Prometheus server scrapes. Is it allowed to have two scrapes giving out the same timestamp for a given metric? Are they creating duplicates? Thank you. When Prometheus is running in localhost or same host. timestamp; prometheus; promql; Share. Get the adress and add the desired port to it. Why is this important? When having scrape issue like prometheus_target_scrapes_sample_duplicate_timestamp_total, it's important to know which target has the problematic metrics for monitoring purposes - in our cases, we want teams to own their services and be able to get alert/investigate issues relevant only for their services. scrape_configs: - job_name: node static_configs: - targets: ['localhost:9100'] When Prometheus is running in different environment or host Prometheus stores all metrics data as time series, i. Provide timestamps with the metric in the testdata I have my node up and running and I’m using the built in /metrics endpoint. This is what happens for every other metric that uses Prometheus' timestamp, when it goes away. The @ modifier allows overriding the timestamp relative to which the For production systems, we recommend a minimum value of 15s for Prometheus scrape interval and a 10000 (10s) value for RabbitMQ's collect_statistics_interval. Saving a csv with current date and time. 33. The lookbehind window can be augmented on a per-query basis via last_over_time() function. These delays are usually in the range 0. $ kubectl -n <namespace> get pod prometheus-k8s-0 2/2 Running 1 122m prometheus-k8s-1 2/2 Running 1 122m Look at the logs of each of them, there should be a log line such as: $ kubectl -n <namespace> logs prometheus-k8s-0 level=warn ts=2021-01-04T15:08:55. NET Metrics scraped by Prometheus and delivered to Grafana with a project which should be eneabled to send OpenTelemetry Data. In the prometheus (prometheus1) being scraped, it could be scraping two endpoints (1 at a 15s interval and another at 30s). Prometheus server. Looking at the code By default Prometheus returns the most recent values if they were posted during the last 5 minutes. Copy link Member Author. It plays a vital role in collecting and analyzing metrics to gain insights A date command mistake on a prometheus agent change the date a week or so in the future. At first, you have to write a new promehetus collector that implements Collector interface, then you provide your logic to set the custom timestamp for your metric. adjust-timestamps boolean flag to adjust scrape timestamps by up to 2ms to align them to the intended scrape schedule and thus achieve better timestamp compression. Notice, that this is not a timestamp of actual change, but only of "window frame" associated with evaluation of function change, last_over_time( [30d:]) to "stretch out" results. The last working version was otelcol-contrib_v0. Needless to say, we have lots of requirements towards docker monitoring. scrape. Reload to refresh your session. The fields have generic keys based on the type of the prometheus metric. Scrape Configuration. How you would like to collect your Prometheus metrics?. e. notification-queue-capacity: 10000--alertmanager. yaml -n monitoring For production systems, we recommend a minimum value of 15s for Prometheus scrape interval and a 10000 (10s) value for RabbitMQ's collect_statistics_interval. Use case. 496Z warn internal/metricsbuilder. If I set with fine-grained scrape interval, it will increase the burden of prometheus server when have bundle of metrics. This was a breaking change between Prometheus 2. This indicator contains multiple attributes, and the historical values may be modified. This is a web server that exposes the timestamped metrics in the *. But the most of data rows have some additional data in curly braces. In Openshift, scraped metrics are returned as JSON and it seems that the otel prometheus receiver does no Pushing metrics. To view all available command-line flags, The Prometheus Java client allows us to instrument our applications with minimal effort by exposing real-time metrics for Prometheus to scrape and monitor. Troubleshooting. This prometheus agent pushed remote write data to several prom servers and those are broken with msg="Appending scrape report failed" err="out of bounds". The built-in textfile collector does not support timestamped This can be done with combination of functions changes, timestamp and last_over_time. Prometheus TimeStamp Returns Null. Just like you would write in a YAML configuration . I didn't realize this and ran into some odd behaviour with histograms, expecting that each data point I added to the histogram object in the client library would have the timestamp of that event attached, and then the scraper was just grabbing all of these data points, There is however the timestamp() function, which will give the timestamp of a sample. Prometheus target metrics scrape record time not match the A timestamp will be returned by the exporter along with the value. Below are logs of collector are attached. scrape components instances opting in to clustering use target labels and a consistent hashing algorithm to determine ownership for each of the targets between the cluster Learn about prometheus. Non-zero delays in scrape target's response handler, which generates the response for Prometheus. I’ve noticed that, after a few days, Prometheus collects and stores its metrics as time series data, i. The second solution means that metrics will never go stale and expire which might not be what you want. From the prometheus Hello all, for the past weeks I’ve been an issue with Grafana Alloy. CSV). the timestamp Prometheus append to a sample is the time the GET Scrape Timeout: The scrape timeout is the maximum time Prometheus will wait for a target to respond to a scrape request before considering it a failed scrape attempt. demo namespace: demo rule_files: - /etc/prometheus/rules. Scrape Timeout: Hi, I’m trying to debug an error with app exported Prom metrics; getting: prom-prometheus-server-6979dc7bb-t9jm9 prometheus-server ts=2022-01-04T21:28:20. The issue I’m seeing is duplicate metrics. scrape() returns a stream of tables with the following columns: _time: Data timestamp; _measurement: prometheus; _field: Prometheus metric name (_bucket is trimmed from histogram metric names); _value: Prometheus metric value; url: URL metrics were scraped from; Label columns: A column for each Prometheus label. Servers NTP synced. Each of these servers reports mem_used_bytes metric. Each stage can export the most recent heartbeat timestamp it has --agent: false--alertmanager. With these values, Prometheus doesn't scrape RabbitMQ too frequently, and Actual timestamp vs Scrape timestamp in Prometheus time series. scrape components instances opting in to clustering use target labels and a consistent hashing algorithm to determine ownership for each of the targets between the cluster It means I can query data with timestamp that prometheus. # This is a YAML-formatted file. For samples from a scrape, this is when Prometheus begins the scrape. notification-queue-capacity: 10000--auto-gomaxprocs: true--auto-gomemlimit In these situations, the Pushgateway functions as a proxy scrape target for the application; the application sends it metrics to Pushgateway, Prometheus scrapes Pushgateway. You signed out in another tab or window. It supports aligning of scrape timings for different targets via scrape_align_interval option in scrape configs - see these docs. This seems to be allowed in the documentation: # Minimalistic line: Proposal. Actual timestamp vs Scrape timestamp in Prometheus time series. I know this is not bugs in prometheus and I am not suggesting to put that as a default of course, but for those edge cases being able to discard the timestamps would be great. In order to do some data analysis, we want to extract metrics in a usable/simple format (e. 943Z I've see other threads/posts (on github, stackoverflow) where people have requested capability in prometheus to be able to filter or mark metrics as stale/expired based on the metrics' timestamp (when last pushed to pushgateway). The __address__ source will be queried for a host name or ip I would like Prometheus to scrape metrics every hour and display these hourly scrape events in a table in a Grafana dashboard. Hi, does prometheus_remote_write sink still work correctly for prometheus_scrapesource -> prometheus_remote_write sink flow? As far as I understand the Prometheus remote write protocol needs a To associate a custom timestamp with a Prometheus metric: Write a custom collector - you can't use the built-in Gauge class in the Python client. yaml Describe the bug On a fresh deployment (EKS with one node), the ADOT collector have fails to scrap data. Environment and logs Dockerized Prometheus node with 256GB of RAM and 12cores, monitoring around 1. end up with a vector of ts of the last scrape or query errors. The Prometheus API, on the other hand, is used to query and retrieve metrics that have already been collected and stored in the time-series database. Prometheus omits time series from query results if the timestamp for which the query is executed is more than 5 minutes away from the nearest sample. Returns the last Prometheus should be able to scrape metrics without encountering conflicting values for the same timestamp, or the application/service should emit metrics with unique timestamps. 9--config. Flag: Value--alertmanager. Not using docker Even with "honor_timestamps" set to True, it should not impact the order. 1 (same issue with v2. nameOverride: "" fullnameOverride: "" # Valid values are "daemonset", PromLabs - We teach Prometheus-based monitoring and observability. It will try 30 seconds (scrape_timeout) to get the metrics if it can't scrape in this time it will time out. Prometheus labels become telegraf tags. - Last Scrape: Timestamp of the last scrape. Any other double-delta, even if it is just 1ms, will consume at least 16bits. . TestCase 2: Set honor_timestamps : false inside scrape_configs of Prometheus Receiver configuration. Scrape configuration is a critical component of Prometheus, defining how metrics are collected from targets. All data point snapshots builders inherit the scrapeTimestampMillis() method that you can use to set the scrape timestamp. Please guide us What did you do? Upgraded to 1. How to reproduce it? No response This can happen hundreds of thousands of times per second without causing any monitoring traffic. I see the following ts=2024-08-16T Thanks for all the info so far. Occasionally you will need to monitor components which cannot be scraped. Scraping gathers data; the API provides access to that data for analysis. It may not be self evident that prometheus_io_scrape translates to prometheus. timeout--auto-gomemlimit. The query uses Prometheus subqueries - see However, there’s no timestamp, which implies Prometheus uses scrape time for that (but you still can provide your own). 0 (the last recent pre 2 version) and replaced the log file on server INT with the log file from PROD in an attempt to trigger Prometheus to re-scrape the imported log file but probably this is type Options struct { ExtraMetrics bool // Option used by downstream scraper users like OpenTelemetry Collector // to help lookup metric metadata. Templates have the ability to run queries against the local database, iterate over data, use conditionals, format data, etc. 1ms - 100ms depending on the distance between Prometheus and scrape target. I was adding a unit test for NHCB ( #14978 ) and noticed that after calling OpenMetricsParser. io/scrape. So as long as the time between when the scrape starts and the time Component(s) receiver/purefa What happened? Description The receiver is failing to scrape the Prometheus endpoint since PR21100 was commited. With these values, Prometheus doesn't scrape RabbitMQ too frequently, and RabbitMQ doesn't update metrics unnecessarily. Related topics Topic Replies Views Activity; How to find the fluctuation of a metric ??? Notice, that range used here should be more that scrape_interval, timestamp( ) - returns timestamp associated with result of last function. When enabled, for each instance scrape, Prometheus stores a sample in the following additional time series: scrape_timeout_seconds. 32. There are 100 VM with Node-exporter and cAdvisor in my server. Follow asked May 9, 2019 This is possible using NewMetricWithTimestamp provided in the prometheus golang client, but for exposing it, you have to do a little code. 563' | . There are two options. It seems that this goes against the prometheus way of working and that is fine. yml scrape_configs: - job_name: "OpenTel" # metrics_path defaults to '/metrics' # scheme defaults to 'http'. The scrape interval is specified in seconds and determines the frequency of data collection. Either fix the timestamps reported by the device or set expiration: -1 under the prometheus output to avoid metrics being deleted. Forward metrics from your Prometheus instance I am trying to figure out how I can get prometheus to scrape the termination time, specifically the time a Node was terminated giving a UNIX timestamp, of a Node inside a kubernetes cluster. However, it's also possible to provide explicit client-side timestamps for samples in the Prometheus metrics exposition format . Should be false for Prometheus. Prometheus is a powerful open-source monitoring and alerting toolkit widely adopted in modern cloud-native environments. As I collect the metrics every 30 seconds on my vCenters, I put the scrape interval to 30s in Grafana but let the Prometheus scrape by default on my VM. 76. 1 to v2. 30, Julien Pivotto now added support for tuning this scrape timestamp tolerance duration using the @shakuzen I means the prometheus scrape timestamp is not engough precise, may be 3 seconds, or 10 seconds (etc, depends on how much I set the prometheus scrape interval granularity) deviation with real timestamp when issue happened. Modified 3 years, 5 months ago. Stack Overflow for Teams Where developers & technologists share private knowledge with coworkers; Advertising & Talent Reach devs & technologists worldwide about your product, service or employer brand; OverflowAI GenAI features for Teams; OverflowAPI Train & fine-tune LLMs; Labs The future of collective knowledge sharing; About the company It appears that Prometheus does not accept my metrics. Because in the above case my global scrape_interval is 15s and if I set the target scrape_interval less than 10s then the Prometheus does not discover the target but everything works if I I removed the timestamps from the Prometheus exporter and adjusted the scrape interval on my Prometheus and Grafana dashboards. Read csv file using Prometheus. scrape_interval: 1m static_configs a couple of days i am trying to figure out a problem dealing with . Prometheus collects and stores its metrics as time series data, i. While the command-line flags configure immutable system parameters (such as storage locations, amount of data to keep on disk and in memory, etc. Import a csv file which was created at specific time instant in Python. These non-deterministic delays may introduce big relative errors to scrape timings for scrape_interval values smaller than one second. Date and Time have since been synchronized back on the faulty prometheus agent but the problem remains. g. In this case Prometheus will use the timestamp at the time of the actual scrape. We should obviously fix that. Prometheus will attach timestamp of scrape to the value. P. e metrics information is stored along with the timestamp at which it was recorded, optional key-value pairs called as labels can also be stored along with metrics. Query. Store a timestamp with Prometheus metrics. Official readme: If you push metrics at time t1, you might be tempted to believe that Prometheus will scrape them with that same timestamp t1. See timestamp() docs. That was (I think) the problem. Thank for your response soonly! What did you see instead? On the diagram above, Prometheus monitors several application servers simultaneously. Suppose my /metrics endpoint is kind of slow, and it takes 15 seconds after sending the request, before the server begins sending the response. If Prometheus sends the request at time t, and finishes reading the response at time t + 15, what timestamp will Prometheus assign to the collected samples?t or t + 15? Or something in between? If the answer is t + 15, how does In Prometheus 2. What did you do? If you activate the feature flag --enable-feature=created-timestamp-zero-ingestion in Prometheus, you must also activate the feature flag --enable-feature=native-histograms, otherw I try to get a metric from Prometheus API with the exact timestamp stored in the database. To associate a custom timestamp with a Prometheus metric: Write a custom collector - you can’t use the built-in Gauge class in the Python client. 1. ts=2024-04-24T09:49:10. Scrape_interval and scrape_timeout are setting a Prometheus provides a functional query language called PromQL (Prometheus Query Language) that lets the user select and aggregate time series data in real time. On the page about exposition formats I can see that it is possible to specify a timestamp on the scrape_timeout and scrape_duration_seconds? Check for an annotation prometheus. Saved searches Use saved searches to filter your results more quickly If the dshackle pods are not sending a suitable 'Content-Type' header when scraped then you'll need to set the fallback_scrape_protocol configuration option for the target. ; Write a custom exporter. yml. For high-frequency Saved searches Use saved searches to filter your results more quickly I updated on server INT Prometheus v1. We will later configure Prometheus to scrape this /probe endpoint to trigger a probe and collect the same metrics. Scrape Interval: This parameter defines how frequently Prometheus should scrape metrics from the configured targets. The column label is the If a prometheus receiver, fails to scrape an endpoint, the output shows something like: 2021-01-12T21:11:10. That however, is an anti-pattern and will turn Prometheus into a push-based system. The returned metrics include a probe_ssl_earliest_cert_expiry metric – the value of this metric is a Unix timestamp that tells us when the TLS certificate is about to expire (hopefully Flag: Value--alertmanager. For other log formats, refer to Your device is reporting old timestamps (probably not synced to NTP). 24 exposed 0 as timestamp (its was bug, solved in latest release). - Scrape Duration: Time taken for the scrape. Consider following example: Better Stack Prometheus metrics Start collecting metrics in 5 minutes. But I cannot figure out how to get the timestamp at which my metric last changed it’s value. For example, this sample has a timestamp of 1395066363000 All prometheus. benjaminhuo changed the title Add ignore_timestamp to prometheus scrape metrics input plugin Add override_timestamp to prometheus scrape metrics input plugin Sep 6, 2022. If it is Hi team, I’m facing a problem regarding the scraping my nodejs application , I don’t have metrics anymore, is stop collect metrics after I restart the nodejs application, is working one hour then I receive the bellow Hi all, I'm using splunk-otel-collector to send Openshift metrics to our Splunk Enterprise. kubectl apply -f additional-scrape-configs. Currently when using /federate on a prometheus endpoint, I get the granularity of data equal to that of the scrape interval of the prometheus scraping that endpoint. x and 3. go:1345 level=debug component="scrape manager" scrape_pool=OpenTelemetry_OriginalTestProjekt I’m running 2 large Prometheus servers in a datacenter, both scraping the same targets. ; Gauges for measuring fluctuating values, such Suppose we are collecting the same metrics for one month and now we want to modify the metrics to have extra label (in the old data as well), how can we do that. ), the It seems like the Prometheus endpoint scraping is failing due to an issue with the timestamp. Prometheus then simply asks the service instance every 15 or 30 seconds (or whatever you configure) about the current counter value and stores that value together with the scrape timestamp as a sample. /promtool check metrics elapsed_scantime_count no help text Thank you @schneifi, that link was helpful - the Prometheus logs have more info than the alert does, including the name of the scrape_pool, which helps narrowing this down 👍 (In our case it was a duplicated ServiceMonitor, so Prometheus was scraping the same endpoint twice and ended up with different values during the same scrape) Configuring Prometheus instances. you can use an alternative Prometheus-like monitoring solution I work on - VictoriaMetrics and/or vmagent. It simply ingests whatever it receives from the scrape and adds a timestamp of the instant the scrape took place. “Ignored” is probably the wrong word here. When Prometheus scrapes an endpoint, this becomes the timestamp for the measurements that are acquired at that time. One approach is to patch PGW (see prometheus/pushgateway#338) to skip the timestamp check. Federation allows a Prometheus server to scrape selected time series from another Prometheus server. Hot Network Questions Validate that the honor_timestamps were handled and the start_timestamp present in the transformed OTLP data by the Prometheus Receiver contains the same input timestamp given in the testdata. If avg is selected, the average value of the datapoints will be calculated and no explicit timestamp will be returned by the endpoint. mvsivwc acnxt ygfjfef mfzjqax yvuwzq tbmxzk zod cut bcdxyzm xhliva
