Let's see how easy it is to hook it in to OpsGenie Configuration - Alertmanager. This integration takes advantage of configurable webhooks available with Prometheus Alertmanager. Support for Prometheus is built-in to Alerta so no special configuration is required other than to ensure the webhook URL is correct in the Alertmanager config file. Example alertmanager.yml receivers sectio alertmanager config Raw. alertmanager.yml global: slack_api_url: <hidden> pagerduty # The labels by which incoming alerts are grouped together. For example, # multiple alerts coming in for cluster=A and alertname=LatencyHigh would # be batched into a single group. group_by: ['alertname','host'] group_wait: 30s: group_interval: 5m: repeat_interval: 12h: receiver: slack-alerts: routes. After set alert rules and alertmanager configuration in values.yaml: You can put in there the configuration you want (for example take inspiration by the blog post you linked) and it will be used by Prometheus to handle the alerts. For example, a simple rule could be set like this: serverFiles: alerts: | ALERT cpu_threshold_exceeded IF (100 * (1 - avg by(job)(irate(node_cpu{mode='idle'}[5m.
The AlertManager configuration is passed to the AlertManager with the --config.file flag as defined in the docker-compose file. In the above configuration file, we are telling the AlertManager that if you receive an alert with a name ( httpd_down for example), you should route the alert to appropriate receiver In this example, we have instructed AlertManager to route any notifications classified as an outage to PagerDuty. Further, if the Alert matches a specific team we send it to a chat solution, and if the Alert matches a particular group we send it to a mailing list. We'll see how to apply these labels to alerts further down when we configure alerts in Prometheus. Note that these matches are. Now we need to configure Alertmanager to send us mails whenever an alert reaches the firing state. We need to add the below configuration in alertmanager.yml sudo vi /usr/local/bin/alertmanager.
See an example of the final As a last step in our Prometheus Alertmanager configuration, we have to add the newly created receiver to an existing route, so that we could easily test our setup in the next section.

A working NFS server is required to create persistent volumes. Note that NFS server configuration is not covered in this article, but the way we set it up can be found here. Our NFS server IP address is 10.11.1.
Example of Using a Receiver Hook for Autoscaling of a service. By using a receiver hook to scale services, you can implement autoscaling by integrating with external services. In our example, we'll use Prometheus to monitor the services and Alertmanager to POST to the URL. Installing Prometheu Alertmanager (optional) Configs API (optional) Distributor. The distributor service is responsible for handling incoming samples from Prometheus. It's the first stop in the write path for series samples. Once the distributor receives samples from Prometheus, each sample is validated for correctness and to ensure that it is within the configured tenant limits, falling back to default ones in. More info about queries and some examples can be found on the official Prometheus documentation page. Alerts. Alerts can notify us as soon as a problem occurs, so we'll know immediately when something goes wrong with our system. Prometheus provides alerting via its Alertmanager component. We can follow the same steps as for Prometheus Server. Under the Resources -> Workload tab, go to. For example, in the next sections, you will be able to interact with a 'Prometheus' Kubernetes API object which defines the initial configuration and scale of a Prometheus server deployment. Operators read, write and update CRDs to persist service configuration inside the cluster. Prometheus Operator. The Prometheus Operator for Kubernetes provides easy monitoring definitions for.
For example, to configure a PVC that claims local persistent storage for Prometheus, use: apiVersion: v1 kind: ConfigMap metadata: name: cluster-monitoring-config namespace: openshift-monitoring data: config.yaml: | prometheusK8s: volumeClaimTemplate: metadata: name: localpvc spec: storageClassName: local-storage resources: requests: storage: 40Gi.
