> Nodetool compactionstats reports only on active compactions, if nothing is active, you see only:
> {quote}$nodetool tablestats
> pending tasks: 0
> {quote}
> but in the MBean Compaction/TotalCompactionsCompleted there are recent statistic in events/second for:
>  * Count
>  * FifteenMinueRate
>  * FiveMinueRate
>  * MeanRate
>  * OneMinuteRate
> It would be useful to see in addition:
> {quote}pending tasks: 0
> compactions completed: 20
>     1 minute rate:    0/second
>    5 minute rate:    2.3/second
>   15 minute rate:   4.6/second
> {quote}
