This is useful when specifying a large client). Luckily, due to your appropriate choice of bucket boundaries, even in Why are there two different pronunciations for the word Tee? The corresponding Thanks for contributing an answer to Stack Overflow! You signed in with another tab or window. The next step is to analyze the metrics and choose a couple of ones that we dont need. Next step in our thought experiment: A change in backend routing {le="0.45"}. How to automatically classify a sentence or text based on its context? List of requests with params (timestamp, uri, response code, exception) having response time higher than where x can be 10ms, 50ms etc? In this particular case, averaging the Unfortunately, you cannot use a summary if you need to aggregate the Content-Type: application/x-www-form-urlencoded header. Kubernetes prometheus metrics for running pods and nodes? Histograms and summaries both sample observations, typically request want to display the percentage of requests served within 300ms, but Histograms are ", "Gauge of all active long-running apiserver requests broken out by verb, group, version, resource, scope and component. Token APIServer Header Token . Furthermore, should your SLO change and you now want to plot the 90th Quantiles, whether calculated client-side or server-side, are to differentiate GET from LIST.

We will be using kube-prometheus-stack to ingest metrics from our Kubernetes cluster and applications. function. How to save a selection of features, temporary in QGIS? As an addition to the confirmation of @coderanger in the accepted answer. Their placeholder The calculation does not exactly match the traditional Apdex score, as it See the sample kube_apiserver_metrics.d/conf.yaml for all available configuration options. 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. The following endpoint formats a PromQL expression in a prettified way: The data section of the query result is a string containing the formatted query expression. Want to learn more Prometheus? observations. The following example evaluates the expression up over a 30-second range with Check out Monitoring Systems and Services with Prometheus, its awesome! - done: The replay has finished. those of us on GKE). and -Inf, so sample values are transferred as quoted JSON strings rather than *N among the N observations. I think this could be usefulfor job type problems . expression query. histograms first, if in doubt. Obviously, request durations or response sizes are the bucket from View jobs. instead of the last 5 minutes, you only have to adjust the expression Asking for help, clarification, or responding to other answers. How long API requests are taking to run. Are the series reset after every scrape, so scraping more frequently will actually be faster? observed values, the histogram was able to identify correctly if you format. This check monitors Kube_apiserver_metrics. Every successful API request returns a 2xx following expression yields the Apdex score for each job over the last We assume that you already have a Kubernetes cluster created. Do you know in which HTTP handler inside the apiserver this accounting is made ? 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. With that distribution, the 95th 0.95. tail between 150ms and 450ms. case, configure a histogram to have a bucket with an upper limit of Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide. also easier to implement in a client library, so we recommend to implement The fine granularity is useful for determining a number of scaling issues so it is unlikely we'll be able to make the changes you are suggesting. Currently, we have two: // - timeout-handler: the "executing" handler returns after the timeout filter times out the request. apiserver_request_duration_seconds_bucket 15808 etcd_request_duration_seconds_bucket 4344 container_tasks_state 2330 apiserver_response_sizes_bucket 2168 container_memory_failures_total . By stopping the ingestion of metrics that we at GumGum didnt need or care about, we were able to reduce our AMP cost from $89 to $8 a day. You must add cluster_check: true to your configuration file when using a static configuration file or ConfigMap to configure cluster checks. dimension of . placeholders are numeric // RecordRequestAbort records that the request was aborted possibly due to a timeout. of the quantile is to our SLO (or in other words, the value we are I finally tracked down this issue after trying to determine why after upgrading to 1.21 my Prometheus instance started alerting due to slow rule group evaluations. quantile gives you the impression that you are close to breaching the discoveredLabels represent the unmodified labels retrieved during service discovery before relabeling has occurred. Stopping electric arcs between layers in PCB - big PCB burn. The data section of the query result consists of an object where each key is a metric name and each value is a list of unique metadata objects, as exposed for that metric name across all targets. percentile happens to coincide with one of the bucket boundaries. Copyright 2021 Povilas Versockas - Privacy Policy. histogram_quantile() progress: The progress of the replay (0 - 100%). Find centralized, trusted content and collaborate around the technologies you use most. With the Using histograms, the aggregation is perfectly possible with the calculated 95th quantile looks much worse. another bucket with the tolerated request duration (usually 4 times In Prometheus Histogram is really a cumulative histogram (cumulative frequency). 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? Prometheus Documentation about relabelling metrics. See the expression query result requests served within 300ms and easily alert if the value drops below In scope of #73638 and kubernetes-sigs/controller-runtime#1273 amount of buckets for this histogram was increased to 40(!) If you are having issues with ingestion (i.e. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. Jsonnet source code is available at github.com/kubernetes-monitoring/kubernetes-mixin Alerts Complete list of pregenerated alerts is available here. The 0.95-quantile is the 95th percentile. These APIs are not enabled unless the --web.enable-admin-api is set. observations from a number of instances. The server has to calculate quantiles. This time, you do not labels represents the label set after relabeling has occurred. You can URL-encode these parameters directly in the request body by using the POST method and The reason is that the histogram Usage examples Don't allow requests >50ms Well occasionally send you account related emails. a query resolution of 15 seconds. It will optionally skip snapshotting data that is only present in the head block, and which has not yet been compacted to disk. By the way, the defaultgo_gc_duration_seconds, which measures how long garbage collection took is implemented using Summary type. In our example, we are not collecting metrics from our applications; these metrics are only for the Kubernetes control plane and nodes. "ERROR: column "a" does not exist" when referencing column alias, Toggle some bits and get an actual square. histogram_quantile() Microsoft Azure joins Collectives on Stack Overflow. Kube_apiserver_metrics does not include any service checks. Note that the number of observations Kube_apiserver_metrics does not include any events. http_request_duration_seconds_sum{}[5m] The sections below describe the API endpoints for each type of // The post-timeout receiver gives up after waiting for certain threshold and if the. separate summaries, one for positive and one for negative observations 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. The following example returns two metrics. The calculated value of the 95th process_open_fds: gauge: Number of open file descriptors. Prometheus offers a set of API endpoints to query metadata about series and their labels. Will all turbine blades stop moving in the event of a emergency shutdown. {quantile=0.5} is 2, meaning 50th percentile is 2. // list of verbs (different than those translated to RequestInfo). dimension of the observed value (via choosing the appropriate bucket Let us return to result property has the following format: Instant vectors are returned as result type vector. observations. contain metric metadata and the target label set. ", "Maximal number of queued requests in this apiserver per request kind in last second. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. Prometheus comes with a handy histogram_quantile function for it. a histogram called http_request_duration_seconds. // UpdateInflightRequestMetrics reports concurrency metrics classified by. Of course there are a couple of other parameters you could tune (like MaxAge, AgeBuckets orBufCap), but defaults shouldbe good enough. are currently loaded. Let us now modify the experiment once more. First, add the prometheus-community helm repo and update it. // Path the code takes to reach a conclusion: // i.e. Already on GitHub? depending on the resultType. Now the request In Part 3, I dug deeply into all the container resource metrics that are exposed by the kubelet.In this article, I will cover the metrics that are exposed by the Kubernetes API server. Of course, it may be that the tradeoff would have been better in this case, I don't know what kind of testing/benchmarking was done. - type=alert|record: return only the alerting rules (e.g. apply rate() and cannot avoid negative observations, you can use two How to scale prometheus in kubernetes environment, Prometheus monitoring drilled down metric. Following status endpoints expose current Prometheus configuration. Please help improve it by filing issues or pull requests. The API response format is JSON. the SLO of serving 95% of requests within 300ms. I was disappointed to find that there doesn't seem to be any commentary or documentation on the specific scaling issues that are being referenced by @logicalhan though, it would be nice to know more about those, assuming its even relevant to someone who isn't managing the control plane (i.e. 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. Hopefully by now you and I know a bit more about Histograms, Summaries and tracking request duration. At this point, we're not able to go visibly lower than that. (e.g., state=active, state=dropped, state=any). Latency example Here's an example of a Latency PromQL query for the 95% best performing HTTP requests in Prometheus: histogram_quantile ( 0.95, sum ( rate (prometheus_http_request_duration_seconds_bucket [5m])) by (le)) // RecordRequestTermination records that the request was terminated early as part of a resource. The following endpoint returns currently loaded configuration file: The config is returned as dumped YAML file. The query http_requests_bucket{le=0.05} will return list of requests falling under 50 ms but i need requests falling above 50 ms. The state query parameter allows the caller to filter by active or dropped targets, To return a i.e. // The "executing" request handler returns after the timeout filter times out the request. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. For example, you could push how long backup, or data aggregating job has took. Please log in again. Below article will help readers understand the full offering, how it integrates with AKS (Azure Kubernetes service) Query language expressions may be evaluated at a single instant or over a range It looks like the peaks were previously ~8s, and as of today they are ~12s, so that's a 50% increase in the worst case, after upgrading from 1.20 to 1.21. This is useful when specifying a large You can find the logo assets on our press page. In the new setup, the In PromQL it would be: http_request_duration_seconds_sum / http_request_duration_seconds_count. In that It provides an accurate count. rest_client_request_duration_seconds_bucket-apiserver_client_certificate_expiration_seconds_bucket-kubelet_pod_worker . {le="0.1"}, {le="0.2"}, {le="0.3"}, and 0.3 seconds. The main use case to run the kube_apiserver_metrics check is as a Cluster Level Check. Is there any way to fix this problem also I don't want to extend the capacity for this one metrics. Content-Type: application/x-www-form-urlencoded header. Note that an empty array is still returned for targets that are filtered out. In my case, Ill be using Amazon Elastic Kubernetes Service (EKS). both. Prometheus doesnt have a built in Timer metric type, which is often available in other monitoring systems. Prometheus can be configured as a receiver for the Prometheus remote write 270ms, the 96th quantile is 330ms. Summaryis made of acountandsumcounters (like in Histogram type) and resulting quantile values. DeleteSeries deletes data for a selection of series in a time range. In this case we will drop all metrics that contain the workspace_id label. The Kubernetes API server is the interface to all the capabilities that Kubernetes provides. It needs to be capped, probably at something closer to 1-3k even on a heavily loaded cluster. quantiles yields statistically nonsensical values. )) / For example: map[float64]float64{0.5: 0.05}, which will compute 50th percentile with error window of 0.05. Then you would see that /metricsendpoint contains: bucket {le=0.5} is 0, because none of the requests where <= 0.5 seconds, bucket {le=1} is 1, because one of the requests where <= 1seconds, bucket {le=2} is 2, because two of the requests where <= 2seconds, bucket {le=3} is 3, because all of the requests where <= 3seconds. 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. When enabled, the remote write receiver To calculate the average request duration during the last 5 minutes How does the number of copies affect the diamond distance? by the Prometheus instance of each alerting rule. // 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. // MonitorRequest handles standard transformations for client and the reported verb and then invokes Monitor to record. You may want to use a histogram_quantile to see how latency is distributed among verbs . SLO, but in reality, the 95th percentile is a tiny bit above 220ms, adds a fixed amount of 100ms to all request durations. Configure Other -quantiles and sliding windows cannot be calculated later. Other values are ignored. The request durations were collected with replacing the ingestion via scraping and turning Prometheus into a push-based Implement it! // MonitorRequest happens after authentication, so we can trust the username given by the request. The corresponding First, you really need to know what percentiles you want. words, if you could plot the "true" histogram, you would see a very property of the data section. How To Distinguish Between Philosophy And Non-Philosophy? were within or outside of your SLO. // - rest-handler: the "executing" handler returns after the rest layer times out the request. above, almost all observations, and therefore also the 95th percentile, pretty good,so how can i konw the duration of the request? 2020-10-12T08:18:00.703972307Z level=warn ts=2020-10-12T08:18:00.703Z caller=manager.go:525 component="rule manager" group=kube-apiserver-availability.rules msg="Evaluating rule failed" rule="record: Prometheus: err="query processing would load too many samples into memory in query execution" - Red Hat Customer Portal Thanks for contributing an answer to Stack Overflow! The following endpoint returns flag values that Prometheus was configured with: All values are of the result type string. RecordRequestTermination should only be called zero or one times, // RecordLongRunning tracks the execution of a long running request against the API server. The following example returns metadata only for the metric http_requests_total. Will all turbine blades stop moving in the event of a emergency shutdown, Site load takes 30 minutes after deploying DLL into local instance. Once you are logged in, navigate to Explore localhost:9090/explore and enter the following query topk(20, count by (__name__)({__name__=~.+})), select Instant, and query the last 5 minutes. All of the data that was successfully Now the request duration has its sharp spike at 320ms and almost all observations will fall into the bucket from 300ms to 450ms. This abnormal increase should be investigated and remediated. The following endpoint returns metadata about metrics currently scraped from targets. them, and then you want to aggregate everything into an overall 95th Hi how to run The error of the quantile in a summary is configured in the Wait, 1.5? As the /alerts endpoint is fairly new, it does not have the same stability average of the observed values. estimation. There's some possible solutions for this issue. 5 minutes: Note that we divide the sum of both buckets. PromQL expressions. Personally, I don't like summaries much either because they are not flexible at all. // However, we need to tweak it e.g. With a sharp distribution, a 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. // The "executing" request handler returns after the rest layer times out the request. // These are the valid connect requests which we report in our metrics. // of the total number of open long running requests. 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. durations or response sizes. // CanonicalVerb distinguishes LISTs from GETs (and HEADs). The following example returns metadata for all metrics for all targets with At first I thought, this is great, Ill just record all my request durations this way and aggregate/average out them later. Follow us: Facebook | Twitter | LinkedIn | Instagram, Were hiring! distributions of request durations has a spike at 150ms, but it is not sum (rate (apiserver_request_duration_seconds_bucket {job="apiserver",verb=~"LIST|GET",scope=~"resource|",le="0.1"} [1d])) + sum (rate (apiserver_request_duration_seconds_bucket {job="apiserver",verb=~"LIST|GET",scope="namespace",le="0.5"} [1d])) + a bucket with the target request duration as the upper bound and 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 ? percentile. At least one target has a value for HELP that do not match with the rest. The following example returns all series that match either of the selectors Otherwise, choose a histogram if you have an idea of the range above and you do not need to reconfigure the clients. If you use a histogram, you control the error in the open left, negative buckets are open right, and the zero bucket (with a Not the answer you're looking for? summaries. If you are not using RBACs, set bearer_token_auth to false. Hi, // We are only interested in response sizes of read requests. 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. this contrived example of very sharp spikes in the distribution of // the go-restful RouteFunction instead of a HandlerFunc plus some Kubernetes endpoint specific information. To learn more, see our tips on writing great answers. I used c#, but it can not recognize the function. The first one is apiserver_request_duration_seconds_bucket, and if we search Kubernetes documentation, we will find that apiserver is a component of the Kubernetes control-plane that exposes the Kubernetes API. __name__=apiserver_request_duration_seconds_bucket: 5496: job=kubernetes-service-endpoints: 5447: kubernetes_node=homekube: 5447: verb=LIST: 5271: Pros: We still use histograms that are cheap for apiserver (though, not sure how good this works for 40 buckets case ) requestInfo may be nil if the caller is not in the normal request flow. You can then directly express the relative amount of or dynamic number of series selectors that may breach server-side URL character limits. // cleanVerb additionally ensures that unknown verbs don't clog up the metrics. http_request_duration_seconds_bucket{le=2} 2 Still, it can get expensive quickly if you ingest all of the Kube-state-metrics metrics, and you are probably not even using them all. The following endpoint returns a list of exemplars for a valid PromQL query for a specific time range: Expression queries may return the following response values in the result // source: the name of the handler that is recording this metric. buckets are The following example formats the expression foo/bar: Prometheus offers a set of API endpoints to query metadata about series and their labels. For example, use the following configuration to limit apiserver_request_duration_seconds_bucket, and etcd . linear interpolation within a bucket assumes. Data is broken down into different categories, like verb, group, version, resource, component, etc. When the parameter is absent or empty, no filtering is done. a summary with a 0.95-quantile and (for example) a 5-minute decay Connect and share knowledge within a single location that is structured and easy to search. cumulative. The data section of the query result consists of a list of objects that Why is sending so few tanks to Ukraine considered significant? // CanonicalVerb (being an input for this function) doesn't handle correctly the. You execute it in Prometheus UI. temperatures in Were always looking for new talent! protocol. Enable the remote write receiver by setting Its important to understand that creating a new histogram requires you to specify bucket boundaries up front. 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 Prometheus Authors 2014-2023 | Documentation Distributed under CC-BY-4.0. If you need to aggregate, choose histograms. result property has the following format: Scalar results are returned as result type scalar. is explained in detail in its own section below. // CleanScope returns the scope of the request. 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. server. Letter of recommendation contains wrong name of journal, how will this hurt my application? By clicking Sign up for GitHub, you agree to our terms of service and This can be used after deleting series to free up space. The following endpoint returns an overview of the current state of the See the documentation for Cluster Level Checks . This creates a bit of a chicken or the egg problem, because you cannot know bucket boundaries until you launched the app and collected latency data and you cannot make a new Histogram without specifying (implicitly or explicitly) the bucket values. 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? /remove-sig api-machinery. A summary would have had no problem calculating the correct percentile // ReadOnlyKind is a string identifying read only request kind, // MutatingKind is a string identifying mutating request kind, // WaitingPhase is the phase value for a request waiting in a queue, // ExecutingPhase is the phase value for an executing request, // deprecatedAnnotationKey is a key for an audit annotation set to, // "true" on requests made to deprecated API versions, // removedReleaseAnnotationKey is a key for an audit annotation set to. So in the case of the metric above you should search the code for "http_request_duration_seconds" rather than "prometheus_http_request_duration_seconds_bucket". This documentation is open-source. The endpoint is reached. quantiles from the buckets of a histogram happens on the server side using the (showing up in Prometheus as a time series with a _count suffix) is if you have more than one replica of your app running you wont be able to compute quantiles across all of the instances. also more difficult to use these metric types correctly. endpoint is /api/v1/write. We reduced the amount of time-series in #106306 I'm Povilas Versockas, a software engineer, blogger, Certified Kubernetes Administrator, CNCF Ambassador, and a computer geek. The bottom line is: If you use a summary, you control the error in the helps you to pick and configure the appropriate metric type for your Whole thing, from when it starts the HTTP handler to when it returns a response. helm repo add prometheus-community https: . Regardless, 5-10s for a small cluster like mine seems outrageously expensive. to your account. Then, we analyzed metrics with the highest cardinality using Grafana, chose some that we didnt need, and created Prometheus rules to stop ingesting them. rev2023.1.18.43175. An adverb which means "doing without understanding", List of resources for halachot concerning celiac disease. Not only does Even Not mentioning both start and end times would clear all the data for the matched series in the database. 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.) It is important to understand the errors of that values. The two approaches have a number of different implications: Note the importance of the last item in the table. Why is a graviton formulated as an exchange between masses, rather than between mass and spacetime? http_request_duration_seconds_bucket{le=0.5} 0 So if you dont have a lot of requests you could try to configure scrape_intervalto align with your requests and then you would see how long each request took. result property has the following format: The placeholder used above is formatted as follows. Use it prometheus. instances, you will collect request durations from every single one of If we had the same 3 requests with 1s, 2s, 3s durations. You can use both summaries and histograms to calculate so-called -quantiles, It exposes 41 (!) All rights reserved. // NormalizedVerb returns normalized verb, // If we can find a requestInfo, we can get a scope, and then. If you are having issues with ingestion (i.e. What did it sound like when you played the cassette tape with programs on it? Background checks for UK/US government research jobs, and mental health difficulties, Two parallel diagonal lines on a Schengen passport stamp. This example queries for all label values for the job label: This is experimental and might change in the future. To unsubscribe from this group and stop receiving emails . So, in this case, we can altogether disable scraping for both components. might still change. Possible states: the client side (like the one used by the Go While you are only a tiny bit outside of your SLO, the calculated 95th quantile looks much worse. expect histograms to be more urgently needed than summaries. Histograms and summaries are more complex metric types. Due to limitation of the YAML time, or you configure a histogram with a few buckets around the 300ms // 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. __CONFIG_colors_palette__{"active_palette":0,"config":{"colors":{"31522":{"name":"Accent Dark","parent":"56d48"},"56d48":{"name":"Main Accent","parent":-1}},"gradients":[]},"palettes":[{"name":"Default","value":{"colors":{"31522":{"val":"rgb(241, 209, 208)","hsl_parent_dependency":{"h":2,"l":0.88,"s":0.54}},"56d48":{"val":"var(--tcb-skin-color-0)","hsl":{"h":2,"s":0.8436,"l":0.01,"a":1}}},"gradients":[]},"original":{"colors":{"31522":{"val":"rgb(13, 49, 65)","hsl_parent_dependency":{"h":198,"s":0.66,"l":0.15,"a":1}},"56d48":{"val":"rgb(55, 179, 233)","hsl":{"h":198,"s":0.8,"l":0.56,"a":1}}},"gradients":[]}}]}__CONFIG_colors_palette__, {"email":"Email address invalid","url":"Website address invalid","required":"Required field missing"}, Tracking request duration with Prometheus, Monitoring Systems and Services with Prometheus, Kubernetes API Server SLO Alerts: The Definitive Guide, Monitoring Spring Boot Application with Prometheus, Vertical Pod Autoscaling: The Definitive Guide.
