Nagios and Cacti

[Justin Ellison]

I can't believe I'm posting such nasty code, but, it works for me.  I
need to get around to doing some error trapping and what not, but it's
been nuts at work.

This script is used to grab traffic stats from routers, etc via SNMP,
check if it's within the critical/warning levels, and create/update an
RRD file.

You need the RRDs perl module installed from the RRD homepage, and
Net::SNMP from CPAN.

Add to checkcommands.cfg:
define command{
        command_name    check_traffic
        command_line    $USER1$/check_traffic -H $HOSTADDRESS$ -C $ARG1$
-w $ARG2$ -c $ARG3$  -i $ARG4$ -s $ARG5$
        }

Add to services.cfg for the hosts you wish to monitor:

check_command	check_traffic!rostring!warn!crit!iface!ver

where rostring is the snmp community string, warn is the percentage for
warning (ie 85 - if traffic is above 85% of total, warning is returned),
crit is critical percentage, iface is a comma separated list of
interface numbers you want to monitor corresponding to snmp .ifDescr.x,
and ver is the snmp version to use (1 or 2 only).

You'll want to edit check_traffic and change the $dbpath variable to
point to your cacti rra directory.  Also make sure that the nagios user
has write permissions into that directory.

Then, manually add the rrd files as data sources in Cacti, and viola!
pretty graphs!
