Custom PostgreSQL plugin for collecting metrics from Openshift Pods

[rasmus_edgar_fi]

I have customized the original PostgreSQL plugin and added a service_name field in order to connect to the OpenShift PostgreSQL services running in pods.

The custom plugin installs in the tenant without issue and I can enter and save login credentials.

No metrics are collected.

Am I supposed to deploy the custom plugin manually on the OpenShift nodes in /opt/dynatrace/oneagent/plugin_deployment or somewhere else?

I seem to have missed that plugins are not supported when running dynatrace from containers in pods, even though it is clearly stated in the documentation:
https://www.dynatrace.com/support/help/technology-support/supported-technologies-and-versions/#plugi...

So to actually monitor postgreSQL OpenShift services, some workaround must be configured.
