Monitoring OpenShift

[Sadiq]

What are the best tools to monitor the overall perfromance and to set thresholds for Alerting in OpenShift Container Platform .

Thanks/Regards

There are many monitoring solutions that are openshift aware, and these are different from cluster metrics (Hawkular/Heapster or Prometheus).

I've seen people going with Prometheus more often for both cluster metrics, monitoring and APM.

For alerting, Prometheus has a component 'AlertManager' that does exactly that.

We had it configured to send alerts both by email and on Slack.

It's a great and powerful framework (not solution), to be used in conjuction with dashboarding tools like Grafana.

I know Dynatrace is offering its agent 'oneagent' through the Red Hat Container Registry, but I have yet to test it.

One very promising solution is https://sysdig.com (cloud sysdig, not console sysdig, the open source tool).

@RickMartins - can you contribute here too please?

Aside from the standard Hawkular/Heapster and Prometheus setups mentioned already, I have done work with a few different 3rd party tools.

CoScale and Sysdig both have powerful tools for use with OpenShift. I quite like both of these offerings as OpenShift specific monitoring. Outside the realm of monitoring, but still worth the look when looking into Sysdig, is their Sysdig Falco product. Some interesting security bits there.

New Relic also recently released a Kubernetes monitoring product which works well with OpenShift and can be paired with their other products as part of a larger APM and Infrastructure monitoring strategy for the organization.

Finally, OCP 3.11 ships with Prometheus and Grafana!!

Just seen that New Relic announced their acquisition of CoScale yesterday. Would expect their stack to get a whole lot better very soon.

While we're on the subject of OpenShift and monitoring, I'll take this opportunity to plug http://uncontained.io which has a guide that attempts to give some high level recommendations around an OpenShift monitoring solution, as well as a ton of other useful articles around cloud, devops, and containerization topics:
