attempt recovery on service CRITICAL with nrpe

[Steve Bonds]

This is probably drifting dangerously offtopic into "stupid grep tricks",
but here's what I use:

Instead of:

ERS=`ps -eaf | grep ns-slapd | grep -v "grep" | wc -l`

use:

ERS=`ps -eaf | grep [n]s-slapd | wc -l`

The [] is normally used to match one of many chars.  In this case it only
matches one.  The "[n]" literal shows up in the process list on the grep
command.  However, [n] evaluated by grep down to become "n" does not match
the "[n]" it sees in the process list so your grep won't show up.

It'll make more sense if you just try it.  ;-)
