Federation allows for pulling aggregates up the hierarchy. Prometheus supports two types of rules which may be configured and thenevaluated at regular intervals: recording rules and alertingrules. Create namespace and deploy It has the same configuration format and actions as target relabeling. Suggestions cannot be applied from pending reviews. Then in your Prometheus CRD you would write: In Prometheus the instance label uniquely identifies a target within a job. interface{}in Go is similar to a void pointer in C. 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: |- [prometheus] added support for external_labels to server.global section of prometheus chart. Prometheus data model facilitates flexible and accurate time series and is especially useful if … privacy statement. This approach resembles the way Kubernetes organizes data with labels. Docker Desktop for Mac / Docker Desktop for Windows: Click the Docker icon in the toolbar,select Preferences, then select Daemon. @deboshrestha you will need to do that somehow with your configuration management. Applying suggestions on deleted lines is not supported. If the file i… Each cluster must have a unique kubernetes_cluster_name label to distinguish metrics once they are merged in VictoriaMetrics. One use for this is ensuring a HA pair of Prometheus servers with different external labels send identical alerts. @reddare we are doing it the same way i.e. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. I tried using configmaps here but running into an issue - so opened this one - #1325. Labels in Prometheus Alerts: Think Twice Before Using Them. 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"}" 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. Add this suggestion to a batch that can be applied as a single commit. The Prometheus Operator creates a new kind of object called Prometheus. Already on GitHub? My prometheus just stands up with the error: @Kampe , I solved this by using replicaExternalLabelName: "__replica__" : The $labels variable holds the label key/value pairs of an alert instance. To model this in Prometheus, we can add several groups of endpoints to a single job, adding extra labels to each group of targets. By clicking “Sign up for GitHub”, you agree to our terms of service and {{ $root.Values.server.global | toYaml | trimSuffix "\n" | indent 6 }}. This helps to reduce disk space usage dramatically. I thought I needed to add the value explicitly for the helm chart to pick it up. Note that this worked in my testing, but there may be a better approach. external_labels: monitor: 'prometheus' scrape_configs: - job_name: 'prometheus' static_configs: - targets: ['localhost:9090'] 4. I was thinking the line below, but after running some more tests I think I was incorrect on the premise of this PR. Alert relabeling is applied to alerts before they are sent to the Alertmanager. However, I'll relent that there may be a better way of doing this overall or something I have missed, so only approve accordingly. Showing 1-4 of 4 messages. 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. 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. 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. 1. [prometheus] Double merge of global configs with no clear override method. Via API? Now we want to run the Prometheus as a Service so that in case of server restart service will come automatically. Where I can get this endpoint? helm-charts/charts/prometheus/templates/server/cm.yaml, Closing as I don't think this is needed per comments above and linked issue. In addition the two Prometheus servers have slightly different external labels, so their data does not conflict if remote storage is in use. Which issue this PR fixes Addresses this issue: #340 Note that this worked in my testing, but there may be a better approach. 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. # This is a YAML-formatted file. Thanks! For a given service which is deployed to both clusters we deploy the same Prometheus Rules. Windows Server: C:\ProgramData\docker\config\daemon.json 3. The changes are only applied if all rule files are well-formatted. __name__is a reserved word for a metric name. How can we achieve this the Prometheus Operator? The best way to do this is via the daemon.json, which islocated at one of the following locations by default. Sign in cluster: ${CLUSTER_NAME} 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. Suggestions cannot be applied while viewing a subset of changes. 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. cluster: cluster-name Use external labels in prometheus alert rule IF clause? 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. The configured external labels can be accessed via the $externalLabels variable. 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. This applies whether you use Prometheus Operator directly or via the helm chart. If you are using Ansible from a Python virtualenv, install jmespathto the same virtualenv via pip. []samplemeans a list of samples. Have a question about this project? This piece adds replica key using Pod name as value for it. These are meant to globally identify the role of that instance. What this PR does / why we need it: Adds support for external_labels to prometheus chart. Addresses this issue: This is especially useful for thanos as it requires these external labels. For example, the query. # Attach these extra labels to all timeseries collected by this Prometheus instance. 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. This is very much a proposed change. Moreover, it manages Prometheus’ configuration and lifecycle. Please, any suggests? Alert relabeling is applied after external labels. This is working in my limited example that I tested and deploy. 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. To configure the Docker daemon as a Prometheus target, you need to specify themetrics-address. Alerts generated with Prometheus are usually sent to Alertmanager to deliver via various media like email or Slack message. Additional detail in issue below. 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.
