The answer is actually rather short: You cannot use the Prometheus/alertmanger supplied with openshift
for application monitoring.
We’ve set up a second prometheus/alertmanager instance in its own namespace that is used for all application monitoring.
We are looking to create a custom rule for Prometheus to generate alerts for other new namespaces that we create.
When I update the prometheus-k8s-rulefiles-0 config-map, my changes are not retained.
The config map is not possible to change based on our neeeds.
How can I make changes so that we can use the existing Prometheus/Alert Manager installed with OpenShift 3.11?
I will appreciate any technical suggestion.
