You can monitor pretty much anything. If you have snmp enabled then all
you need is the OID, but if not you can script it. For example, I
wanted to monitor system load on my email server (also running httpd and
mrtg). I found a program called linux_loadavg_mrtg (written in C) on
the web then in /etc/mrtg/mrtg.cfg I have:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
### Global Config Options
WorkDir: /var/www/mrtg
Options[_]: growright,unknaszero,withzeroes
WithPeak[_]: wmy
Forks: 10
Interval: 5

### loadavg
Target[loadavg]: `/usr/local/bin/linux_loadavg_mrtg`
MaxBytes[loadavg]: 50
Title[loadavg]: Load Average
PageTop[loadavg]: <H2>Load Average on Email Server</H2>
Options[loadavg]: growright,gauge,absolute,nopercent
YLegend[loadavg]: Load Avgerage
ShortLegend[loadavg]: unit
Legend1[loadavg]: Load Average (1min)
Legend2[loadavg]: n/a
Legend3[loadavg]: Maximal 5 Minute Load Average
Legend4[loadavg]: n/a
LegendI[loadavg]: Value:
LegendO[loadavg]: n/a:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
You can find the program at

and more specifically

Google can be so handy at times... 8^)
Hope that helps
