Ceph Data Capture Scripts in Red Hat OpenShift Data Foundation (RHODF)

Issue

In some instances, when degraded performance is experienced. Ceph may be intermittently reporting issues such as blocked ops, slow ops, capability release, cache pressure, etc. This may result in a one-time grab of the logs not being able to capture the issue. In such instances, it may be necessary to run a script continuously to capture the issue while it is temporarily present. The script outlined in this solution is safe to run in the rook-ceph-tools pod continuously. It will capture 244 minutes of continual data at which time it discards the data older than 244 minutes. Additionally, the private notes section in this solution contains additional scripts for more targeted efforts guided by Red Hat Support.
