Well, I can't say enough about this program! IT IS WONDERFUL!  Did I mention it's FREE?!

It is a combination of PERL scripts and a fast C program (called RATEUP) that targets SNMP compliant devices, GETs performance data, writes it to a log, and graphs the result in daily, weekly, monthly and yearly views.   These graphs are embedded into web pages which can be viewed from any modern Web-browser.  This is where your hard work with getting SNMP installed on your NT and/or NetWare servers REALLY pays off.  Check it out live (commented) examples of what MRTG can do, illustrated by graphs created from performance statistics from my Windows NT Server, by clicking here.

Armed with the ability to install SNMP performance monitoring DLLs or NLMs, you can pretty much have MRTG collect and graph information on any statistic.   For example, using SNMP and MRTG, you can monitor statistics on  Windows NT Servers (as above) and NetWare Servers (I am monitoring about 15 useful stats on some NetWare servers at work), collecting information on CPU usage, memory usage, NLMs, volume space remaining, file server reads and writes, etc.

Of course, you can also use MRTG to collect information about routers, switches, hubs and almost anything that will allow SNMP access.  I use MRTG to track temperature and humidity in a computer room (from an APC MeasureUPS module installed in an APC Matrix 5000 UPS.  All you need is an SNMP capable device (with the SNMP agent enabled, of course), and the proper MRTG CFG (config) files.  Here is my collection of them.  Help yourself!  I will be adding more as I find/create them.
