OpenShift caagent-deployment not connecting properly

Products

Issue/Introduction

We are having problems with one of our OpenShift clusters.  The agent itself is connecting but the ApiServer Connection Status is showing 0 instead of 1 and we are not seeing any metadata.

Environment

Release : 10.7.0

Component : APM Agents

Resolution

Here is the Exception in the deployment DEBUG log:

[DEBUG] [IntroscopeAgent.Fabric8ClusterMonitor] Failed to extract information for Namespaces

Basically we are not able to connect to the OpenShift_Connection_Url as specified in the stack trace above (http://openshift.abc123.com)



However in the DEBUG log collection, we see this:

[[email protected]<host>]# oc project caapm
Already on project "caapm" on server "https://openshift.abc123.com:443".


Please use this URL and see if it can connect:
