Unable to track compaction completion

[Rajsekhar Mallick <ra...@gmail.com>]

Hello team,

I have been trying to figure out, how to track the completion of a
compaction on a node.
Nodetool compactionstats show instantaneous results.

I found that system.compaction_in_progress gets me the same details as that
of compactionstats. Also it gets me a id for running compaction.
I was of the view that checking for the same id in
system.compaction_history would fetch me the compaction details after a
running compaction ends.
But no such relationship exists I see.
Please do confirm on the above.

Thanks,
Rajsekhar Mallick

Hi Rajsekhar,

 

I think monitoring the CompactionManagerMBean is what you need.
