[prometheus] added support for external_labels to server.global section of prometheus chart. relabel_configs: - source_labels: ['nodename'] target_label: 'instance' I can manually relabel every target, but that requires hardcoding every hostname into Prometheus, which is not really nice. to your account. Each cluster must have a unique kubernetes_cluster_name label to distinguish metrics once they are merged in VictoriaMetrics. Have a question about this project? Prometheus data model facilitates flexible and accurate time series and is especially useful if … It reads and archives data on the object store. jmespath on deployer machine. If you notice when we deploy it there is a script being called. I was thinking the line below, but after running some more tests I think I was incorrect on the premise of this PR. If the file does notexist, create it. https://github.com/prometheus-community/helm-charts/blob/main/charts/kube-prometheus-stack/values.yaml#L1666, The correct way to do this for all future comers, add env vars on the prometheus-config-reloader container and reference them with $(ENV) in your yaml. Windows Server: C:\ProgramData\docker\config\daemon.json 3. Labels in Prometheus Alerts: Think Twice Before Using Them. I have added endpoint /metrics in my app and this is the config file i have written for prometheus kind: ConfigMap metadata: name: prometheus-config apiVersion: v1 data: prometheus.yml: |- If you can indeed override values without specifically setting them in the values.yml I believe this PR is not needed and can be abandoned.

This is especially useful for thanos as it requires these external labels. Alert relabeling is applied to alerts before they are sent to the Alertmanager. Already on GitHub? Only one suggestion per line can be applied in a batch. Also, this is my first PR to this repo so if I missed the mark anywhere my apologies. As previously discussed, Prometheus is intended to have at least one instance per datacenter usually also with a global Prometheus for global graphing or alerting. To distinguish each Prometheus instance, the sidecar component injects external labels into the Prometheus configuration. Learn how to write alerting rules and configure the Prometheus alertmanager to send concise, easy-to-understand notifications. privacy statement. If you are using Ansible from a Python virtualenv, install jmespathto the same virtualenv via pip. To model this in Prometheus, we can add several groups of endpoints to a single job, adding extra labels to each group of targets. prometheus: front-end-team) for a particular Prometheus (e.g. This is especially useful for thanos as it requires these external labels. This should really be documented somewhere visible. Which issue this PR fixes Addresses this issue: #340 Note that this worked in my testing, but there may be a better approach. First, deploy three instances of a simple example application, which listens and exposes metrics on port 8080. Adds support for external_labels to prometheus chart. Note that this worked in my testing, but there may be a better approach. Add option to customize alias field for opsgenie alerts, [stable/prometheus-operator] Fixed README to reflect prometheus deployment template, https://github.com/prometheus-community/helm-charts/blob/main/charts/kube-prometheus-stack/values.yaml#L1670, https://github.com/prometheus-community/helm-charts/blob/main/charts/kube-prometheus-stack/values.yaml#L1666. I am new in k8s and prometheus operator too and have problems with understanding how to add external_labels for my prometheus-kube-prometheus deployment created by helm. What this PR does / why we need it: Adds support for external_labels to prometheus chart. It will make it so metrics with names container_tasks_state and container_memory_failures_total are completely dropped and will not be stored in the database. Use external labels in prometheus alert rule IF clause? Suggestions cannot be applied while the pull request is closed. The replicaExternalLabelName should remain default in most all cases as its handled by the operator and the default labels it adds on replicas prometheus_replica is valid for most federation tools, Thanos etc. I thought I needed to add the value explicitly for the helm chart to pick it up. For example, the query. In this example, we will add the group="production" label to the first group of targets, while adding group="canary" to the second. We then use alert relabelling to ensure they still send identically labelled alerts, which the Alertmanager will automatically de-duplicate. For cluster name I used: The text was updated successfully, but these errors were encountered: The PrometheusSpec has the externalLabels field, which is just a yaml map of label-value pairs. Wondering the same thing, how did you manage this by chance? How can we achieve this the Prometheus Operator? The $labels variable holds the label key/value pairs of an alert instance. # Default values for prometheus-operator. Additional detail in issue below. You need to just add the labels you want to the Prometheus object under .spec.externalLabels. # Attach these extra labels to all timeseries collected by this Prometheus instance. In addition the two Prometheus servers have slightly different external labels, so their data does not conflict if remote storage is in use. This is working in my limited example that I tested and deploy. Additional detail in issue below. helm-charts/charts/prometheus/templates/server/cm.yaml, Closing as I don't think this is needed per comments above and linked issue. You signed in with another tab or window. https://github.com/prometheus-community/helm-charts/blob/main/charts/kube-prometheus-stack/values.yaml#L1670 # Declare variables to be passed into your templates. External Labels # Prometheus allows the configuration of “external labels” of a given Prometheus instance. On pre-prod we want alerts to be routed to Slack, while on prod they should be routed to Slack and PagerDuty. Applying suggestions on deleted lines is not supported. External labels To set external labels : prometheus['external_labels'] = { 'region' => 'us-west-2', 'source' => 'omnibus', } No external labels are set by default. level=info ts=2020-11-11T06:36:35.745115859Z caller=sidecar.go:165 msg="successfully loaded prometheus external labels" external_labels="{environment="dev", region="cae"}" One use for this is ensuring a HA pair of Prometheus servers with different external labels send identical alerts. Here what we are doing is as @brancz mentioned by adding externalLabels field in that yaml. external_labels: monitor: 'prometheus' scrape_configs: - job_name: 'prometheus' static_configs: - targets: ['localhost:9090'] 4. Prometheus Operator These external labels are added by default if you use Prometheus Operatorversion 0.19.0 (or higher). The configured external labels can be accessed via the $externalLabels variable. It has the same configuration format and actions as target relabeling. Now we want to run the Prometheus as a Service so that in case of server restart service will come automatically. count(app_version_updated) by (version) Have a question about this project? added support for external_labels to global section of prometheus chart. However, I'll relent that there may be a better way of doing this overall or something I have missed, so only approve accordingly. Thanks! This helps to reduce disk space usage dramatically. You will learn to deploy a Prometheus server and metrics exporters, setup kube-state-metrics, pull and collect those metrics, and configure alerts with Alertmanager and dashboards with Grafana. to your account. __name__is a reserved word for a metric name. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. privacy statement. The rule files can be reloaded at runtime by sending SIGHUPto the Prometheusprocess. Addresses this issue: Sign in kube-prometheus and where the manifests has the prometheus.yaml file. #340 I would suggest adding a label to each namespace that you want to scan for ServiceMonitors (e.g. Sign in cluster: ${CLUSTER_NAME} We’ll occasionally send you account related emails. Prometheus monitoring is quickly becoming the Docker and Kubernetes monitoring tool to use. I was able to fetch Cluster Name, but since I am using Helm Operator with 2 replicas HA for Prometheus, not sure how can Replica (or POD) name can be retrieved dynamically. This applies whether you use Prometheus Operator directly or via the helm chart. externalLabels: Can you please tell me in this externalLabels fields how can i pass my cluster name if I have to pick it this way - kubectl config current-context. Suggestions cannot be applied while viewing a subset of changes. In there we are doing a simple sed which is adding that line in the prometheus.yaml file based on the current-context of the k8s cluster. I alos don't see where the "external_labels" var is used in the chart? You must change the existing code in this line in order to create a valid suggestion. @deboshrestha you will need to do that somehow with your configuration management. {{ $root.Values.server.global | toYaml | trimSuffix "\n" | indent 6 }}. By clicking “Sign up for GitHub”, you agree to our terms of service and # This is a YAML-formatted file. The primary data structure for dealing with time series data is the sample, defined as: The metric name of the sample is encoded in a special __name__ label in the Labelsmap. Alerts generated with Prometheus are usually sent to Alertmanager to deliver via various media like email or Slack message. It would probably be good to read the reader of the Prometheus operator and just go through the getting started, to get a feeling of the concepts involved. the front-end-team Prometheus). The best way to do this is via the daemon.json, which islocated at one of the following locations by default. The important part here is the labels — we must assign the label prometheus: kube-prometheus so the Prometheus server will look for this target and the second label in the matchLabels section so the ServiceMonitor will point to our gpu-exporter only. [prometheus] Double merge of global configs with no clear override method. Can you please show me how its possible to add? My prometheus just stands up with the error: @Kampe , I solved this by using replicaExternalLabelName: "__replica__" : For a given service which is deployed to both clusters we deploy the same Prometheus Rules. []samplemeans a list of samples. I don't know about helm but in the Prometheus object you can just add the externalLabels field. With the Prometheus Operator v0.19.0 and above, ServiceMonitors can be selected outside the Prometheus namespace via the serviceMonitorNamespaceSelector field of the Prometheus resource. You signed in with another tab or window. Federation allows for pulling aggregates up the hierarchy. This piece adds replica key using Pod name as value for it. The issue is, if we add external labels to a Prometheus that has a conflicting label name-value pair with any of the remote reads, the remote read fails. The Prometheus Operator creates a new kind of object called Prometheus. This suggestion has been applied or marked resolved. I am trying to edit prometheus.yaml getting by, kubectl get secret -n monitoring prometheus-kube-prometheus -ojson | jq -r '.data["prometheus.yaml"]' | base64 -d. but its impossible and wrong way I think. Add this suggestion to a batch that can be applied as a single commit. These are meant to globally identify the role of that instance. The values showed up in the config as expected and Thanos picked them up. To include rules in Prometheus, create a filecontaining the necessary rule statements and have Prometheus load the file viathe rule_files field in the Prometheus configuration.Rule files use YAML. This guide explains how to implement Kubernetes monitoring with Prometheus. As your setup grows, you will likely end up running separate Prometheus servers for dev and prod, so it makes sense to apply the env label via external_labels rather than applying to each individual target themselves. Hi guys, I am evaluating Cortex as a backend so it is required externalLabels to be something like: externalLabels: Where I can get this endpoint? The $value variable holds the evaluated value of … Prometheus log snippet: Already on GitHub? As Thanos aims to aggregate data across all instances, providing a consistent set of external labels becomes crucial! Via API? Jesse Meng: 11/8/17 10:19 PM: I have same prometheus alert rules applying for all clusters, and for some alert, I just want to enable them in production clusters. In Prometheus the instance label uniquely identifies a target within a job. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. external_labels: monitor: 'scalyr-blog' rule_files: - 'prometheus.rules.yml' scrape_configs: - job_name: 'prometheus' # Override the global default and scrape targets from this job every 5 seconds. Prometheus supports two types of rules which may be configured and thenevaluated at regular intervals: recording rules and alertingrules. interface{}in Go is similar to a void pointer in C. Let me know if you have any other questions. external_labels section is important – it labels all the metrics sent from Prometheus. Linux: /etc/docker/daemon.json 2. The remote read configuration has a conflict with the external labels and it is not documented very well. This suggestion is invalid because no changes were made to the code.

I tried using configmaps here but running into an issue - so opened this one - #1325. Hi! Showing 1-4 of 4 messages. If the file i… To achieve this vanilla Prometheus, it looks like we should apply an external label to the global Prometheus config and use this in the AlertManager routing config e.g. @brancz Thanks for the prompt response, that's exactly what I'm looking for . To configure the Docker daemon as a Prometheus target, you need to specify themetrics-address. We’ll occasionally send you account related emails. The changes are only applied if all rule files are well-formatted. Suppose we have two independent Kubernetes clusters, prod and pre-prod. I see that the node exporter provides the metric node_uname_info that contains the hostname, but how do … Then in your Prometheus CRD you would write: Suggestions cannot be applied on multi-line comments. Moreover, it manages Prometheus’ configuration and lifecycle. Click Advanced.

Alert relabeling is applied after external labels. Successfully merging this pull request may close these issues. Alerting rules allow us to define alert conditions based on Prometheus expression language expressions and to send notifications about firing alerts to an external service. This is very much a proposed change. Use external labels in prometheus alert rule IF clause? https://github.com/prometheus-operator/prometheus-operator/issues/455 At the core of Prometheus is a time-series database that can be queried with a powerful language for everything – this includes not only graphing but also alerting. Prometheus is my go-to tool for monitoring these days. The version is reported as a label in the app_version (say) metric like so: app_version_updated{instance="eu99",version="1.5.0-abcdefg"} I've tried a number of Prometheus queries to extract the version label as a string from the latest member of this time series, to no effect. 1. This approach resembles the way Kubernetes organizes data with labels. This component is capable of running queries on Prometheus servers’ PromQL interface.
