We'll take the feedback on updating CE and review, but I can't promise
anything in the short term.
In the past GroundWork has not offered services on top of CE other
than a migration service to our paid subscription products.  I see
your point in how a setup and tweak service is valuable, especially in
the absence of an on-demand or other training offering to educate the
first time GroundWork Monitor user.
Cutting down messages is one of the most important parts of our
services engagements.  We call it 'calibration' and aim to reduce
false positives to less than 1% in any 24 hour period.  You need to
take a baseline of your system, and then day by day review the alarms
that would be generated and determine the false ones.  Threshold or
other configuration settings need to be changed to eliminate these.
We choose to do this before notifications are turned on to real
contacts because then it's too late to avoid fatigue.  If you still
can't get false positives down then you may want to consider whether
the things you are monitoring are really worth waking you up at 2 in
the morning for, and eliminating them from your coverage.  We find you
get the most value from a small number of checks, but I'm sure you
already know that which is why you've got your average # of services
down to 7 on each host.
