If you previously had checkpointer enabled (and you have some checkpoints), then you restart a node and disable checkpoints, you would still show old checkpoints. Could this confuse node operators?

You could also show information on whether the checkpointer is currently enabled or not.

You could also show information on whether the checkpointer is currently enabled or not.

You mean to only show it if the checkpointer is enabled? I think this would be good.

Alternative is to show the status of the checkpointer directly:
consensus.checkpointer.enabled/heights or possibly consensus.state.checkpointer.enabled/heights?

I notice for the consensus we tend to display "domain view" (current solution), whereas for the runtimes we tend to show status of independent components (alternative solution).

[martintomazic]

I have kept is simple and only show it if checkpointer is enabled.
