Subject Re: Most important Master metrics?
Date Sat, 23 Apr 2011 21:14:30 GMT
Whether it is up or not and memory consumed.  Normally it does little
except when it goes log splitting.  Then we burn CPU and some memory
though work was done to make sure we stream nicely so we don't OOME.

We'll add in master metrics soon.  IIRC, it does cluster-wide request
rate which is an nice-to-have.
