Re: Slow OSD detection

[Mark Nelson <mark.nelson@inktank.com>]

It'd be nice if something like slow OSD detection could exist outside of 
calamari and itself by an event that we record in the logs and make 
available via the admin socket (so that calamari could pick it up). 
That way folks could get it into logstash and other system monitoring 
tools (say PCP/Nagios/etc).
