If your compaction strategy is Leveled the number of sstables in each level is
a good indication that compactions are keeping up.

You can do so in two ways:
1) direct observation:
You can keep an eye on the number of pending compactions. This will
fluctuate with load, compaction strategy, ongoing repairs and nodes
bootstrapping but generally the pattern is it should trend towards 0.
There have been a number of bugs in past
What is a good way to determine whether or not compaction is falling
behind? I read a couple things earlier that suggest nodetool
compactionstats might not be the most reliable thing to use.
