nagios upgrade

[Randal, Phil]

Is there any way you can clone your nagios box to a VM and test on the
cloned box?
 
I've just done that here testing for a planned 2.12 to 3.0.6 upgrade.
 
You'll need to edit your nagios.cfg file to remove one obsolete option,
and there are a few new options to merge in from the example nagios.cfg.
 
I tested the worst-possible migration case - from self-compiled 2.12 to
RPMForge-packaged 3.0.6 RPM.
 
It was fun dealing with all the default directory changes, but not
impossible.
 
If you're compiling from source for both versions it should be a fairly
painless migration.
 
The side.html file is, as far as I remember, the same in both versions,
so I think you can keep your old one and copy over the newly installed
3.0.6 version.
 
My word, of course, is not gospel (and rarely is), so I'd advise you to
test, test, and test again if you can.
 
The directories which change depend on your config - a look at the paths
specified in your nagios.cfg etc will point yopu in the right direction.
(your logs might be in /var/log/nagios/, for example).
 
Cheers,
 
Phil

Subject: [Nagios-users] nagios upgrade



Hi I was planning to upgrade nagios from 2.9 to 3.0.6. We already have
the pnp tool (performance graph at the side bar). 
My first question , while upgrading will the pnp tool get affected or
messed up by any chance?
I just want to be careful enough because nagios is one of our heavely
used application.
 
As a backup plan already the complete nagios is being backed up by the
cron job. 
My second question :
Can i know which directory is the one that is dynamic meaning that keeps
on changing day by day. Let me list some of them here as far as i know:
 
1)nagios/etc
2)nagios/var
 
If there is any can you please list them ....
