Hi, In the 0.5.x series there was a COMPACTION-POOL which kept track of in process, pending and completed compactions. With 0.6.x this seems to have vanished and instead we only have the CompactionManager PendingTasks statistic. Is there also a completed tasks somewhere? Is there any way to determine via nodetool if a compaction or anticompaction is occuring? I'm trying to figure out the cause of random spikes in the Message Deserializer Queue, and wanted to know if there was any correlation with compaction, but with only PendingTasks, I would have to be sampling continuously to catch it, as pending is mostly zero.
Are there other possible causes for a backup in Message Deserializer? My traffic patterns are pretty constant, I don't see spikes in the thread pool completed tasks, and often the rate is below the high water mark for rates.
