journalctl

journalctl

{"command":["journalctl","-u","vpm","-n","200"]}

Standard journalctl arguments, each a separate array element. -u vpm is the one you want most often: vpm is the agent that registers the node and manages everything else on it, so its journal is where registration failures appear with timestamps and across restarts.

Useful variants:

Arguments	Answers
-u vpm -n 200	What has vpm been doing recently
-u vpm --since "10 min ago"	What happened while I reproduced it
-p err -n 100	Errors from every unit
-u kubelet -n 200	Why the Kubernetes stack is unhealthy

Prefer this over docker-logs vpm when you need timestamps, want to span a restart, or want to correlate vpm against another unit.

No captured output on this page yet

This capture cannot be committed until f5-sales-demo/docs-control#795 lands. The journal echoes a line from FRR containing a misspelling, and codespell rejects the file. Editing captured text would make this page describe output that never occurred, so the fix is being made upstream in the managed configuration instead.
