2009/4/20 Dei Bertine deibert...@yahoo.com:
Thank you Jim.
I was hoping to find a step by step direction on this other than the default
documentation posted.
I followed through but did not work which I'm unable to see the host group
details in the admin page.
I defined the host group under hostgroups path verified without errors:
define hostgroup{
hostgroup_name inf-servers
alias SERVERS
members server1,server2,server3,server4,server5
}
Any tips on how to get started on organizing all of my servers into one
hostgroup file?
Thanks again.
Forgive me, I just read the doc I posted and realised it doesn't
contain probably the most important information!
The easiest (in my experience) way to put hosts in to host groups is
by specifying the hostgroups in the host definition.
For example, you create a file
/usr/local/nagios/etc/objects/hostgroups.cfg which just contains the
hostgroups and nothing else for example:
define hostgroup{
hostgroup_name app-ftp
alias Application = FTP Server
}
define hostgroup{
hostgroup_name app-web
alias Application = Web Server
}
Then you can assign hosts to hostgroups in the host definition (which
you might for example put in a file
/usr/local/nagios/etc/objects/hosts.cfg). These will look something
like this:
define host{
use host-bronze,logo-windows_server,generic-host
host_name server001
alias server001 web and ftp server
address 192.168.1.2
hostgroups app-ftp,app-web
parents switch002
}
If/when you upgrade to Nagios3, you'll notice there are even more
powerful tricks you can use for inheritance of objects from multiple
templates.
I hope this helps.
I can heartily recommend you read the book Nagios by Wolfgang Barth.
http://nostarch.com/nagios_2e.htm . It gives an excellent
introduction to how Nagios works, how to set up the configuration
files, how to monitor various kinds of nodes and server and some of
the useful add-ons available for Nagios. The 2nd edition mainly
covers Nagios version 3, so you might need to bear in mind that there
are some differences or possibly consider purchasing the 1st edition
(if it's still available) which covers Nagios version 2.
Cheers,
Jim
