KubeAPIErrorsHigh alert firing due to "too large resource version" in OCP 4
Issue
- We are seeing continuous alerts such as
KubeAPIErrorsHigh
andKubeClientErrors
on the console. - We checked the
kube-apiserver
logs, but everything seems perfectly working and there are no unusual errors to claim this type of alert. What are the reasons behind these alerts? How to avoid them? -
Some examples of the alerts are:
API server is returning errors for 100% of requests for LIST hostsubnets API server is returning errors for 49.21% of requests for LIST networkpolicies API server is returning errors for 48.39% of requests for LIST egressnetworkpolicies API server is returning errors for 48.39% of requests for LIST csidrivers The API server is burning too much error budget
