How can I graph cpu and memory utilisation from prometheus on grafana?
I need to evaluate graphs based on these two metrics above, Where can I put this on grafana? Is it as a query?
I need to know how it works - any help with videos or articles?
First of all, you need to consider what specific metrics you want to display. Prometheus supports many of them:
You can read about all these metrics, as well as the monitoring by prometheus itself, here.
Once the prometheus collects and processes the appropriate metrics, you can take care of Grafana. You have to install it via Helm, for example, and then set port-forwarding to the appropriate pod. Then you will need to authenticate. When it comes to displaying Prometheus data, you need to create a new dashboard and then add a variable for Prometheus. Everything is fully described in this guide. You will find each step described, also with screenshots.
