> The proposal would be to add a couple of additional log cleaner metrics: 
> 1. Time of last log cleaner run 
> 2. Cumulative number of successful log cleaner runs since last broker restart.
> Existing log cleaner metrics (max-buffer-utilization-percent, cleaner-recopy-percent, max-clean-time-secs, max-dirty-percent) do not differentiate an idle log cleaner from a dead log cleaner. It would be useful to have the above two metrics added, to indicate whether log cleaner is alive (and successfully cleaning) or not.
