Prometheus & Grafana
Deployment of Prometheus & Grafana
Prometheus and Grafana provide powerful system health monitoring tools along with visualisation. Both tools are required to be installed only once on the cluster as metrics from across namespaces are collected and displayed.
Deploy the same using Rancher's admin console:
Login into the Rancher admin console
Select your cluster
Install Monitoring app
After installation, click on the Monitoring menu on the left to reach the below page. Click on Prometheus Targets and make sure all scrape URLs have the status "Up". If not, check if the ports indicated on the URL are accessible across nodes. For information on ports to be opened on nodes refer Firewall Requirements.
