Nagios with high server count, how to organize

[Mueller, Karl]

Misao,

Service detail has much too much information to be useful.  We usually
just watch the "Service Problems" page.  If you need to be able to
browse hosts, I would create arbitrary (logical) hostgroups and browse
them with Hostgroup Overview and Hostgroup Summary.  

If you are running 2.0, you can also use Service Groups. 

The way you can split it up by departments is to create hostgroups and
make them contacts for their own hostgroups but not others.
Alternately, you just have hostgroups that they can click through (if
being able to see other hostgroups is not a security issue)

Check out the notification options for hosts to remove the "unreachable"
messages.    In the host objects, you want:

notification_options [d,u,r,f]

remove the "u".  (we use D & R in our setup)

Subject: [Nagios-users] Nagios with high server count, how to organize

This question is more directed to those with 50+ servers to even 1000+
servers. After a point, the service detail page, and even the status
map,
get a little overwhelmed with all the servers on the list. Is there a
way to
organize the server list in a more manageable manner? Can I show just a
certain list of servers I choose, or organize them by area/os/etc? I
plan on
have a few hundred servers on Nagios, and I would prefer not having to
create a new Nagios instance for each department.
Also, this setup would be useful so that I can make sure that department
1
only sees their servers, and department 2 sees another group of servers,
but
department 3 might need to see multiple groups, etc. I haven't found an
easy
way to do this yet.

Also, on dependencies. Can I set up Nagios in a manner that if router 4
is
down, that Nagios won't bother telling me that all the servers behind
router
4 are down? I currently have a setup where these servers are told what
their
parent is, but it still tells me that every server is unreachable when
the
router is down.
