> The current "CommitsCountPerWriter" stats exposed by
> {{SegmentNodeStoreStats}} are hard to follow since there can be too many
> writers at a time. To improve this, a more coarse-grained version of this
> metric should be added, in which commits are recorded for groups of threads.
> The groups should be configurable and represent regexes to be matched by
> individual thread names. An additional group (i.e. "other") will group all
> threads not matching any of the defined group regexes.
> The current behaviour will be split in two:
> * "CommitsCountOtherThreads" will expose a snapshot of threads currently in
> "other" group
> * "CommitsCountPerGroup" will expose an aggregate of commits count per thread
> group for the previous minute.
> Both metrics will be reset each minute.
