CMK version: 2.1.0p11
OS version: CMA 1.5.4

Error message: agent] Success, [special_kube] Agent exited with code 1: Unsupported Kubernetes version ‘v1.19.4’. API Servers with version < v1.21 are known to return incompatible data. Aborting processing API data. Supported versions are v1.21, v1.22, v1.23.CRIT , execution time 2.6 se

Hello, is there any option/solution to monitor older versions of Kubernetes like 1.18.x, 1.19.x from Checmk 2.1? I have no option to force system admins to update Kubernetes…

Thank you for reply

checkmk_kube_agent/deploy/charts/checkmk at main · tribe29/checkmk_kube_agent · GitHub : As per the documentation, the prerequisite is Kubernetes 1.21+ .

Older versions of Kubernetes can be monitored via Checkmk 1.6 or Checkmk 2.0 but then you won’t get all the important information.

Thank you for an answer, Yeah, that is my backup solution to have standalone site with old version 2.0 out of the distributed monitoring solution. Looking for another possibility.
