[mrtg] MRTG "autoconfiguration" script

[Michael W. Lucas]

Hi,

I run MRTG on a whole bunch of systems to graph all sorts of stuff
across both Windows and UNIXlike platforms.  What's more, every so
often I have to add additional MIBs to monitor, and update all of the
config files with that new information.

The obvious thing to do in this case is write a Perl script that
identifies what MIBs the target host supports, walks the tree to
configure a target for each interface, filesystem, CPU, and so forth,
and then spits out a MRTG configuration file.

I know that cfgmaker supports "templates," but templates aren't quite
the same.  Each of my systems has a varying number of filesystems,
CPUs, and so on.

If this would be useful to you, grab it from
http://www.blackhelicopters.org/~mwlucas/mrtgsetup.pl.gz

This targets the following SNMP engines:

net-snmp
Dell Windows agent
SNMP2CA (very new, probably incomplete or otherwise scary)

and spits out a MRTG config file that targets the following on each
host:

network interfaces (all agents)
cpu utilization (all agents)
available memory (all agents, with petty trouble for snmp2ca)
available swap (dell and net-snmp)
disk usage (all agents)
current process count (all agents)
current load (net-snmp)

Be warned: I am not a programmer, and I learned Perl back in the days
of vanilla Perl 4.  This code probably makes babies cry, and would
offend Aleister Crowley if he was still alive.  (Actually, if you dig
him up and show it to him he'll probably be offended anyway.)  But it
works, which is what matters to me.
