Multiple nagios monitors in one machine

[Carroll, Jim P [Contractor]]

I guess I get to eat my words.  ;)
 
That makes sense though.  To a point.  For example, sendmail typically looks
for sendmail.cf at /etc/sendmail.cf.  But you can specify the config file on
the command line.  It makes sense to me to be able to have a daemon default
to a particular fully qualified pathname, but also to be able to specify any
alternative (no matter how silly ;).
 
I remember you sending that e-mail, Russell, now that you mention it.  If I
could blame lack of caffeine, I would.  ;)

The nagios daemon doesn't have any hardcoded paths (you start it with 1
argument, the location of the nagios.cfg file).  However, the CGI's do use a
hardcoded path (look in common/locations.h) for where to find the cgi.cfg. 

For multiple instances of CGI's, you can either re-configure and remake
every time, or use a patch that I made and sent out to the list previously.
It takes advantage of environment variables you can set in the httpd.conf
for each set/location of CGI's.

If anyone wants, I can go back and repost the email I wrote and the patch.

Jim,

I've checked all the cfg files and there isn't any item pointing to any
of the cgi files. So that's out. And like I said, when copying a
statusmap.cgi from another instance/folder to the new one and run the
new instance, I get the error message where it's pointing to the "other"
directory.

Incidentally, how do you do a strings command? hehe

I might be missing something here, but I'm reasonably certain that the
binaries don't have any pathnames to config files hardcoded.  Having said
that, the only reason I can see that this 3rd instance would fail, is that
the config file you're specifying on startup still has the pathname to the
'original' directory.  Try to grep through the config files for this 3rd
instance, for any occurrences of the 'original' directory.

Failing that, do a 'strings' command on each of the binaries and grep for
the 'original' directory.  I suspect you won't find the pathnames hardcoded.
:)

As you mention in another e-mail, I'd be surprised if the gd libraries can't
'support' 3 instances of Nagios.

Hi Jim and Freddy,

I tried doing that by copying the missing cgi files statusmap.cgi,
trends.cgi and hi

stogram.cgi but when I ran that instance of 
nagios and
click on the statusmap, it says it can't find the ORIGINAL directory
these cgi files were originally compiled for. so it won't work.

As for Freddy's comments, what I did was treat every 
installation like a
new installation: deleting the source tree then getting the files from
the tarball but apparently, it can't locate the gd libraries 
for these 3
cgi files from /usr/lib or /usr/local/lib and /usr/include and
/usr/local/include.  But the thing is: if it can't locate the gd
library, why was I able to install it in the first place? Go figure...

Would Ethan Galstad have an answer for this you think? Hi Ethan! =)

Thanks,

Louie

Louie, I don't know why you don't just manually copy a 

working tree into the

3rd target directory, and manually search/replace pathnames 

in the config

files.

maybe you've done some bad operation by the past in this 
directory... did
you tryed to clean the config.cache file before reconfiguring 
? did you tryed to
delete the source tree and to get it again from the tgz 
archive and to try to
recompile it ? are you using multiple users for each version 
of nagios you plan
to deploy ? if yes, check env var for each users...

'hope this help,		Freddy.

I'm trying to do this on just one machine, e.g.,

/opt/nagios/network1
/opt/nagios/network2
/opt/nagios/network3

or

/opt/network1/nagios/
/opt/network2/nagios
/opt/network3/nagios

preferably the first one.  I've successfully installed 

and ran two

monitors, with the first in the directory /opt/nagios 

and another in

/opt/net2/nagios, with the statusmaps and all but I'm just not
successful with doing a third.  The configure error is 

that it's not

locating those gd,png, and jpg libraries.  Which is 

strange, since

it worked for the first two.  Does anybody know what 

may be wrong?

TIA,
Louie
