Please help if you can
I am trying to configure MRTG to monitor Logical Disk Free space on a
Windows 2000 Server. I have downloaded Getif to walk my SNMP Mib files. This
has given a Oid value of:
.1.3.6.1.4.1.311.1.1.3.1.1.6.1.3 logdskFreeMegabytes
I have entered this value into my MRTG.cfg file with the syntax that was
suggested on a on the Web.

I am still relatively inexperienced with MRTG although I have got it running
monitoring all the routers in our organisation I keep reading something
about an RRDtool. Would this help me or is this something else.
I have tried to find the answer to this on the Internet but as yet I am
struggling.
Hope someone can help as it is driving me round the bend!
Cheers
