CPU alert works?

[fuminori-ido-m]

I have two questions.

Q1) README.md says

NodeCPUUsage > 50%

While prometheus-rules/cpu-usage.rules is as follows:

IF (100 - (avg by (instance) (irate(node_cpu{name="node-exporter",mode="idle"}[5m])) * 100)) > 75

CPU Usage threshold could be 75% rather than 50%, right?

Q2) Label "name" doesn't work actually. In my environment, dashboard of node_cpu is as follows:

node_cpu{..., kubernetes_name="prometheus-node-exporter", ...} = 0.15...

So, alert rule label condtion should be as follows, right?:

IF (100 - (avg by (instance) (irate(node_cpu{kubernetes_name="node-exporter",mode="idle"}[5m])) * 100)) > 75

@fuminori-ido-m unfortunately I don't have time to work on this project, however you're free to create your own fork.
