Steps to create a heatmap to show server health for 20+ servers

  • Grafana 9.0.3

I want to build a server health heat map kind of thing where in if any server’s cpu or memory utilisation goes above certain threshold, then that dot of that particular server will turn red. Need to know how I can achieve this. I am using prometheus stack with node exporter giving the required metrics.

Currently I have looked at heatmap and boom table plugin but being fairly new I need some sample dashboard if there to build upon.

Can anyone help


Look at value mapping configuration wherein you can change the color for certain values or range of values.
