Enable In-Cluster Monitoring
There are two options to enable Monitoring on Platform9 Kubernetes.
- During Cluster Creation
- Post Cluster Creation
Enable Monitoring During Cluster Creation
During the create a new cluster wizard an option will be presented to enable a number of Platform9 Kubernetes Addons, Monitoring is one of these Addons. To ensure Monitoring is enabled leave the “Promethues Monitoring” toggle enabled.
Once the cluster has been deployed Platform9 will automatically deploy Monitoring by creating a new Namspance ‘pf9-monitoring’ and leverage a Kubernetes operator to deploy Prometheus, Alertmanager and Grafana.
If you uncheck the “Promethues Monitoring” toggle a warning will display informing you that monitoring will be disabled on this cluster. If monitoring is disabled the Platform9 Monitoring features will not function and the Monitoring dashboards will not populate with any data.
Enable Monitoring Post Cluster Creation
Monitoring may be enabled on any cluster at anytime directly from the Clusters tab on the Infrastructure page. To enable Monitoring select the target cluster and choose the Add-ons section tab and then click on the Edit Add-ons button.
To enable Monitoring, click on the Enable button for the Promethues Monitoring add-on.
Provide the required and optional details to configure the add-on. If the Promethues data needs to stored on a persistent storage, provide the Storage Class Name and PVC option details. If you require to use an existing PV for storing the Promethues data, provide the name for the PV.
