prometheus apiserver_request_duration_seconds_bucket

For our use case, we dont need metrics about kube-api-server or etcd. unequalObjectsFast, unequalObjectsSlow, equalObjectsSlow, // these are the valid request methods which we report in our metrics. {quantile=0.99} is 3, meaning 99th percentile is 3. Possible states: However, because we are using the managed Kubernetes Service by Amazon (EKS), we dont even have access to the control plane, so this metric could be a good candidate for deletion. I usually dont really know what I want, so I prefer to use Histograms. In that library, YAML comments are not included. Sign in They track the number of observations What's the difference between Docker Compose and Kubernetes? I want to know if the apiserver_request_duration_seconds accounts the time needed to transfer the request (and/or response) from the clients (e.g. EDIT: For some additional information, running a query on apiserver_request_duration_seconds_bucket unfiltered returns 17420 series. protocol. By default the Agent running the check tries to get the service account bearer token to authenticate against the APIServer. Why is sending so few tanks to Ukraine considered significant? are currently loaded. One thing I struggled on is how to track request duration. ", "Number of requests which apiserver terminated in self-defense. See the documentation for Cluster Level Checks. becomes. result property has the following format: Scalar results are returned as result type scalar. First, you really need to know what percentiles you want. Histogram is made of a counter, which counts number of events that happened, a counter for a sum of event values and another counter for each of a bucket. observed values, the histogram was able to identify correctly if you Apiserver latency metrics create enormous amount of time-series, https://www.robustperception.io/why-are-prometheus-histograms-cumulative, https://prometheus.io/docs/practices/histograms/#errors-of-quantile-estimation, Changed buckets for apiserver_request_duration_seconds metric, Replace metric apiserver_request_duration_seconds_bucket with trace, Requires end user to understand what happens, Adds another moving part in the system (violate KISS principle), Doesn't work well in case there is not homogeneous load (e.g. Cons: Second one is to use summary for this purpose. You can also measure the latency for the api-server by using Prometheus metrics like apiserver_request_duration_seconds. rev2023.1.18.43175. In our example, we are not collecting metrics from our applications; these metrics are only for the Kubernetes control plane and nodes. Note that the metric http_requests_total has more than one object in the list. histograms and dimension of . requestInfo may be nil if the caller is not in the normal request flow. Kubernetes prometheus metrics for running pods and nodes? You can find more information on what type of approximations prometheus is doing inhistogram_quantile doc. It does appear that the 90th percentile is roughly equivalent to where it was before the upgrade now, discounting the weird peak right after the upgrade. process_open_fds: gauge: Number of open file descriptors. Shouldnt it be 2? // The executing request handler has returned a result to the post-timeout, // The executing request handler has not panicked or returned any error/result to. above and you do not need to reconfigure the clients. Hi, apiserver_request_duration_seconds_bucket metric name has 7 times more values than any other. client). Regardless, 5-10s for a small cluster like mine seems outrageously expensive. "Response latency distribution (not counting webhook duration) in seconds for each verb, group, version, resource, subresource, scope and component.". // TLSHandshakeErrors is a number of requests dropped with 'TLS handshake error from' error, "Number of requests dropped with 'TLS handshake error from' error", // Because of volatility of the base metric this is pre-aggregated one. The state query parameter allows the caller to filter by active or dropped targets, See the License for the specific language governing permissions and, "k8s.io/apimachinery/pkg/apis/meta/v1/validation", "k8s.io/apiserver/pkg/authentication/user", "k8s.io/apiserver/pkg/endpoints/responsewriter", "k8s.io/component-base/metrics/legacyregistry", // resettableCollector is the interface implemented by prometheus.MetricVec. from one of my clusters: apiserver_request_duration_seconds_bucket metric name has 7 times more values than any other. The Kubernetes project currently lacks enough contributors to adequately respond to all issues and PRs. http_request_duration_seconds_bucket{le=0.5} 0 2015-07-01T20:10:51.781Z: The following endpoint evaluates an expression query over a range of time: For the format of the placeholder, see the range-vector result Snapshot creates a snapshot of all current data into snapshots/- under the TSDB's data directory and returns the directory as response. How many grandchildren does Joe Biden have? i.e. Also we could calculate percentiles from it. What's the difference between ClusterIP, NodePort and LoadBalancer service types in Kubernetes? Buckets: []float64{0.05, 0.1, 0.15, 0.2, 0.25, 0.3, 0.35, 0.4, 0.45, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0, 1.25, 1.5, 1.75, 2.0, 2.5, 3.0, 3.5, 4.0, 4.5, 5, 6, 7, 8, 9, 10, 15, 20, 25, 30, 40, 50, 60}. The histogram implementation guarantees that the true prometheus apiserver_request_duration_seconds_bucketangular pwa install prompt 29 grudnia 2021 / elphin primary school / w 14k gold sagittarius pendant / Autor . At this point, we're not able to go visibly lower than that. For example, use the following configuration to limit apiserver_request_duration_seconds_bucket, and etcd . One would be allowing end-user to define buckets for apiserver. Check out Monitoring Systems and Services with Prometheus, its awesome! ", "Maximal number of queued requests in this apiserver per request kind in last second. Histograms and summaries both sample observations, typically request We assume that you already have a Kubernetes cluster created. Thanks for contributing an answer to Stack Overflow! Find centralized, trusted content and collaborate around the technologies you use most. The following endpoint returns the list of time series that match a certain label set. Follow us: Facebook | Twitter | LinkedIn | Instagram, Were hiring! I can skip this metrics from being scraped but I need this metrics. I want to know if the apiserver_request_duration_seconds accounts the time needed to transfer the request (and/or response) from the clients (e.g. Pros: We still use histograms that are cheap for apiserver (though, not sure how good this works for 40 buckets case ) percentile, or you want to take into account the last 10 minutes This causes anyone who still wants to monitor apiserver to handle tons of metrics. label instance="127.0.0.1:9090. Why are there two different pronunciations for the word Tee? the client side (like the one used by the Go total: The total number segments needed to be replayed. Monitoring Docker container metrics using cAdvisor, Use file-based service discovery to discover scrape targets, Understanding and using the multi-target exporter pattern, Monitoring Linux host metrics with the Node Exporter. __name__=apiserver_request_duration_seconds_bucket: 5496: job=kubernetes-service-endpoints: 5447: kubernetes_node=homekube: 5447: verb=LIST: 5271: In that case, the sum of observations can go down, so you mark, e.g. Enable the remote write receiver by setting You must add cluster_check: true to your configuration file when using a static configuration file or ConfigMap to configure cluster checks. with caution for specific low-volume use cases. Drop workspace metrics config. Due to limitation of the YAML The following endpoint evaluates an instant query at a single point in time: The current server time is used if the time parameter is omitted. use the following expression: A straight-forward use of histograms (but not summaries) is to count You can use, Number of time series (in addition to the. Now the request What did it sound like when you played the cassette tape with programs on it? High Error Rate Threshold: >3% failure rate for 10 minutes sum(rate( The actual data still exists on disk and is cleaned up in future compactions or can be explicitly cleaned up by hitting the Clean Tombstones endpoint. Hopefully by now you and I know a bit more about Histograms, Summaries and tracking request duration. // preservation or apiserver self-defense mechanism (e.g. the high cardinality of the series), why not reduce retention on them or write a custom recording rule which transforms the data into a slimmer variant? instances, you will collect request durations from every single one of This one-liner adds HTTP/metrics endpoint to HTTP router. linear interpolation within a bucket assumes. It is not suitable for In our case we might have configured 0.950.01, metric_relabel_configs: - source_labels: [ "workspace_id" ] action: drop. Version compatibility Tested Prometheus version: 2.22.1 Prometheus feature enhancements and metric name changes between versions can affect dashboards. (assigning to sig instrumentation) In my case, Ill be using Amazon Elastic Kubernetes Service (EKS). 4/3/2020. All rights reserved. 0.95. Example: The target process_cpu_seconds_total: counter: Total user and system CPU time spent in seconds. We will be using kube-prometheus-stack to ingest metrics from our Kubernetes cluster and applications. // We are only interested in response sizes of read requests. function. See the sample kube_apiserver_metrics.d/conf.yaml for all available configuration options. dimension of . format. metrics_filter: # beginning of kube-apiserver. // The "executing" request handler returns after the timeout filter times out the request. Its important to understand that creating a new histogram requires you to specify bucket boundaries up front. For example, we want to find 0.5, 0.9, 0.99 quantiles and the same 3 requests with 1s, 2s, 3s durations come in. Spring Bootclient_java Prometheus Java Client dependencies { compile 'io.prometheus:simpleclient:0..24' compile "io.prometheus:simpleclient_spring_boot:0..24" compile "io.prometheus:simpleclient_hotspot:0..24"}. And with cluster growth you add them introducing more and more time-series (this is indirect dependency but still a pain point). contain the label name/value pairs which identify each series. want to display the percentage of requests served within 300ms, but However, it does not provide any target information. How can I get all the transaction from a nft collection? /sig api-machinery, /assign @logicalhan What does apiserver_request_duration_seconds prometheus metric in Kubernetes mean? Run the Agents status subcommand and look for kube_apiserver_metrics under the Checks section. The keys "histogram" and "histograms" only show up if the experimental Its a Prometheus PromQL function not C# function. Configuration The main use case to run the kube_apiserver_metrics check is as a Cluster Level Check. The calculated value of the 95th 5 minutes: Note that we divide the sum of both buckets. Our friendly, knowledgeable solutions engineers are here to help! The following example returns metadata only for the metric http_requests_total. another bucket with the tolerated request duration (usually 4 times You can use both summaries and histograms to calculate so-called -quantiles, rev2023.1.18.43175. histogram_quantile(0.5, rate(http_request_duration_seconds_bucket[10m]) Please help improve it by filing issues or pull requests. Is there any way to fix this problem also I don't want to extend the capacity for this one metrics A set of Grafana dashboards and Prometheus alerts for Kubernetes. Let us return to result property has the following format: The placeholder used above is formatted as follows. negative left boundary and a positive right boundary) is closed both. Changing scrape interval won't help much either, cause it's really cheap to ingest new point to existing time-series (it's just two floats with value and timestamp) and lots of memory ~8kb/ts required to store time-series itself (name, labels, etc.) Adding all possible options (as was done in commits pointed above) is not a solution. Hi how to run property of the data section. How Intuit improves security, latency, and development velocity with a Site Maintenance - Friday, January 20, 2023 02:00 - 05:00 UTC (Thursday, Jan Were bringing advertisements for technology courses to Stack Overflow, What's the difference between Apache's Mesos and Google's Kubernetes, Command to delete all pods in all kubernetes namespaces. temperatures in a bucket with the target request duration as the upper bound and // the post-timeout receiver yet after the request had been timed out by the apiserver. . The helm chart values.yaml provides an option to do this. Quantiles, whether calculated client-side or server-side, are The first one is apiserver_request_duration_seconds_bucket, and if we search Kubernetes documentation, we will find that apiserver is a component of . also more difficult to use these metric types correctly. The data section of the query result has the following format: refers to the query result data, which has varying formats At least one target has a value for HELP that do not match with the rest. corrects for that. You can also run the check by configuring the endpoints directly in the kube_apiserver_metrics.d/conf.yaml file, in the conf.d/ folder at the root of your Agents configuration directory. E.g. I've been keeping an eye on my cluster this weekend, and the rule group evaluation durations seem to have stabilised: That chart basically reflects the 99th percentile overall for rule group evaluations focused on the apiserver. After that, you can navigate to localhost:9090 in your browser to access Grafana and use the default username and password. and the sum of the observed values, allowing you to calculate the to your account. // the target removal release, in "." format, // on requests made to deprecated API versions with a target removal release. fall into the bucket from 300ms to 450ms. time, or you configure a histogram with a few buckets around the 300ms With a broad distribution, small changes in result in The essential difference between summaries and histograms is that summaries This is especially true when using a service like Amazon Managed Service for Prometheus (AMP) because you get billed by metrics ingested and stored. The error of the quantile in a summary is configured in the Letter of recommendation contains wrong name of journal, how will this hurt my application? In this case we will drop all metrics that contain the workspace_id label. the SLO of serving 95% of requests within 300ms. // However, we need to tweak it e.g. The default values, which are 0.005, 0.01, 0.025, 0.05, 0.1, 0.25, 0.5, 1, 2.5, 5, 10are tailored to broadly measure the response time in seconds and probably wont fit your apps behavior. How to automatically classify a sentence or text based on its context? Already on GitHub? // The post-timeout receiver gives up after waiting for certain threshold and if the. This is experimental and might change in the future. calculated 95th quantile looks much worse. How do Kubernetes modules communicate with etcd? If there is a recommended approach to deal with this, I'd love to know what that is, as the issue for me isn't storage or retention of high cardinality series, its that the metrics endpoint itself is very slow to respond due to all of the time series. the request duration within which // status: whether the handler panicked or threw an error, possible values: // - 'error': the handler return an error, // - 'ok': the handler returned a result (no error and no panic), // - 'pending': the handler is still running in the background and it did not return, "Tracks the activity of the request handlers after the associated requests have been timed out by the apiserver", "Time taken for comparison of old vs new objects in UPDATE or PATCH requests". Because if you want to compute a different percentile, you will have to make changes in your code. - in progress: The replay is in progress. Content-Type: application/x-www-form-urlencoded header. First of all, check the library support for Here's a subset of some URLs I see reported by this metric in my cluster: Not sure how helpful that is, but I imagine that's what was meant by @herewasmike. Prometheus doesnt have a built in Timer metric type, which is often available in other monitoring systems. 320ms. Following status endpoints expose current Prometheus configuration. // We correct it manually based on the pass verb from the installer. // of the total number of open long running requests. Though, histograms require one to define buckets suitable for the case. from a histogram or summary called http_request_duration_seconds, kubelets) to the server (and vice-versa) or it is just the time needed to process the request internally (apiserver + etcd) and no communication time is accounted for ? process_max_fds: gauge: Maximum number of open file descriptors. I think this could be usefulfor job type problems . The maximal number of currently used inflight request limit of this apiserver per request kind in last second. Prometheus integration provides a mechanism for ingesting Prometheus metrics. The following example evaluates the expression up at the time actually most interested in), the more accurate the calculated value // The source that is recording the apiserver_request_post_timeout_total metric. above, almost all observations, and therefore also the 95th percentile, Oh and I forgot to mention, if you are instrumenting HTTP server or client, prometheus library has some helpers around it in promhttp package. This is Part 4 of a multi-part series about all the metrics you can gather from your Kubernetes cluster.. Exporting metrics as HTTP endpoint makes the whole dev/test lifecycle easy, as it is really trivial to check whether your newly added metric is now exposed. is explained in detail in its own section below. Will all turbine blades stop moving in the event of a emergency shutdown. PromQL expressions. Summaryis made of acountandsumcounters (like in Histogram type) and resulting quantile values. metrics collection system. // a request. So the example in my post is correct. behaves like a counter, too, as long as there are no negative In principle, however, you can use summaries and It returns metadata about metrics currently scraped from targets. from the first two targets with label job="prometheus". Prometheus. the "value"/"values" key or the "histogram"/"histograms" key, but not So, which one to use? slightly different values would still be accurate as the (contrived) Then, we analyzed metrics with the highest cardinality using Grafana, chose some that we didnt need, and created Prometheus rules to stop ingesting them. kubernetes-apps KubePodCrashLooping the target request duration) as the upper bound. Thanks for reading. Please help improve it by filing issues or pull requests. See the documentation for Cluster Level Checks . This check monitors Kube_apiserver_metrics. In general, we durations or response sizes. We could calculate average request time by dividing sum over count. When the parameter is absent or empty, no filtering is done. Furthermore, should your SLO change and you now want to plot the 90th I recommend checking out Monitoring Systems and Services with Prometheus, its an awesome module that will help you get up speed with Prometheus. The mistake here is that Prometheus scrapes /metrics dataonly once in a while (by default every 1 min), which is configured by scrap_interval for your target.

Then create a namespace, and install the chart. instead the 95th percentile, i.e. )). Other -quantiles and sliding windows cannot be calculated later. Not mentioning both start and end times would clear all the data for the matched series in the database. The following endpoint returns metadata about metrics currently scraped from targets. For example calculating 50% percentile (second quartile) for last 10 minutes in PromQL would be: histogram_quantile (0.5, rate (http_request_duration_seconds_bucket [10m]) Which results in 1.5. average of the observed values. includes errors in the satisfied and tolerable parts of the calculation. Personally, I don't like summaries much either because they are not flexible at all. The reason is that the histogram progress: The progress of the replay (0 - 100%). query that may breach server-side URL character limits. 95th percentile is somewhere between 200ms and 300ms. Why is sending so few tanks to Ukraine considered significant? The data section of the query result consists of a list of objects that To learn more, see our tips on writing great answers. I am pinning the version to 33.2.0 to ensure you can follow all the steps even after new versions are rolled out. buckets and includes every resource (150) and every verb (10). calculated to be 442.5ms, although the correct value is close to replacing the ingestion via scraping and turning Prometheus into a push-based These are APIs that expose database functionalities for the advanced user. URL query parameters: duration has its sharp spike at 320ms and almost all observations will // The executing request handler panicked after the request had, // The executing request handler has returned an error to the post-timeout. if you have more than one replica of your app running you wont be able to compute quantiles across all of the instances. A Summary is like a histogram_quantile()function, but percentiles are computed in the client. Prometheus is an excellent service to monitor your containerized applications. WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. Let us now modify the experiment once more. status code. a quite comfortable distance to your SLO. Microsoft recently announced 'Azure Monitor managed service for Prometheus'. // the go-restful RouteFunction instead of a HandlerFunc plus some Kubernetes endpoint specific information. Note that any comments are removed in the formatted string. The metric is defined here and it is called from the function MonitorRequest which is defined here. kubelets) to the server (and vice-versa) or it is just the time needed to process the request internally (apiserver + etcd) and no communication time is accounted for ? NOTE: These API endpoints may return metadata for series for which there is no sample within the selected time range, and/or for series whose samples have been marked as deleted via the deletion API endpoint. summary if you need an accurate quantile, no matter what the You execute it in Prometheus UI. Obviously, request durations or response sizes are Prometheus Documentation about relabelling metrics. Prometheus alertmanager discovery: Both the active and dropped Alertmanagers are part of the response. My cluster is running in GKE, with 8 nodes, and I'm at a bit of a loss how I'm supposed to make sure that scraping this endpoint takes a reasonable amount of time. OK great that confirms the stats I had because the average request duration time increased as I increased the latency between the API server and the Kubelets. As the /rules endpoint is fairly new, it does not have the same stability centigrade). The corresponding The -quantile is the observation value that ranks at number DeleteSeries deletes data for a selection of series in a time range. An adverb which means "doing without understanding", List of resources for halachot concerning celiac disease. The calculation does not exactly match the traditional Apdex score, as it The following endpoint returns various build information properties about the Prometheus server: The following endpoint returns various cardinality statistics about the Prometheus TSDB: The following endpoint returns information about the WAL replay: read: The number of segments replayed so far. The placeholder is an integer between 0 and 3 with the If we had the same 3 requests with 1s, 2s, 3s durations. I want to know if the apiserver _ request _ duration _ seconds accounts the time needed to transfer the request (and/or response) from the clients (e.g. Their placeholder After doing some digging, it turned out the problem is that simply scraping the metrics endpoint for the apiserver takes around 5-10s on a regular basis, which ends up causing rule groups which scrape those endpoints to fall behind, hence the alerts. 3 Exporter prometheus Exporter Exporter prometheus Exporter http 3.1 Exporter http prometheus Instead of reporting current usage all the time. // This metric is used for verifying api call latencies SLO.
