does anybody uses the Kubernetes- and Docker-KM?
Can anybody share some experience how those KMs are working in a very dynamic environment like containers?
Can you check the availability of the REST API on OpenShift? I can see if anything can be done through the data available from the REST API.
yes, we have the REST API in OpenShift available.
I have a customer which would be interessted in a KM for OpenShift.

we recently produced a solution for monitoring OpenShift.
the way to use this is done via Scripting KM
it should be used in addition to the Kubernetes KM.
both KM and Script are configured to pull data from the same place, being the API server.
Here is the view of items monitored on my OpenShift Cluster:
sample view of all the DaemonSets within OpenShift monitored:
in this case e.g. I can get an alert if the number of replicas is greater than the number of ReadyReplica, which means
some replicas have not reached a ready status.
Using the Kubernetes KM and dashboards I can also, have view of the resources used by the OpenShift related PODs:
to run it, you need to:
import the Script (it's KM repo ready),
push onto a Linux agent the Scripting KM and this plugin.
install jq, from Download jq on the same host as PATROL agent and the Scripting KM, and the plugin
Let me know if you want to have the scripts.
Thanks for your great work.
Could you please share the scripts you used?
Thanks in advance
Added the 2 required plugins as files to the group here. so you can download
