[mrtg] Monitoring Disk Usage In Win2k

Mon May 19 16:55:45 MEST 2003

Hello Group,
	I am trying to use MRTG to monitor disk usage in Win2k. At this
point I have been able to get data and create some graphs but I am not sure
that the output is correct. I have checked the archive mailing list and
FAQ's and though I found some very good information, I did not get some
questions answered. I will list my issues with examples.

1. snmpwalk and MIBS.
	I am able to get the MIB information but I am not sure what some of
the values are. I have commented where I have issue.

.1.3.6.1.2.1.25.2.3.1.3.1 = STRING: "A:\\"
.1.3.6.1.2.1.25.2.3.1.3.2 = STRING: "C:\\ Label:  Serial Number 6c9cd02a"
.1.3.6.1.2.1.25.2.3.1.3.3 = STRING: "D:\\"
.1.3.6.1.2.1.25.2.3.1.3.4 = STRING: "E:\\ Label:New Volume  Serial Number
f0c36b07" # This is the drive I am interested in.
.1.3.6.1.2.1.25.2.3.1.3.5 = STRING: "F:\\ Label:New Volume  Serial Number
24f42082"
.1.3.6.1.2.1.25.2.3.1.3.6 = STRING: "Virtual Memory"
.1.3.6.1.2.1.25.2.3.1.4.1 = INTEGER: 0
.1.3.6.1.2.1.25.2.3.1.4.2 = INTEGER: 512
.1.3.6.1.2.1.25.2.3.1.4.3 = INTEGER: 0
.1.3.6.1.2.1.25.2.3.1.4.4 = INTEGER: 4096 # Is this the block size?
.1.3.6.1.2.1.25.2.3.1.4.5 = INTEGER: 4096
.1.3.6.1.2.1.25.2.3.1.4.6 = INTEGER: 65536
.1.3.6.1.2.1.25.2.3.1.5.1 = INTEGER: 0
.1.3.6.1.2.1.25.2.3.1.5.2 = INTEGER: 71032799
.1.3.6.1.2.1.25.2.3.1.5.3 = INTEGER: 0
.1.3.6.1.2.1.25.2.3.1.5.4 = INTEGER: 503416319 # Is this the max size? If
so, what format and how do I get this into MRTG format? (1)
.1.3.6.1.2.1.25.2.3.1.5.5 = INTEGER: 9438179
.1.3.6.1.2.1.25.2.3.1.5.6 = INTEGER: 47483
.1.3.6.1.2.1.25.2.3.1.6.1 = INTEGER: 0
.1.3.6.1.2.1.25.2.3.1.6.2 = INTEGER: 11746421
.1.3.6.1.2.1.25.2.3.1.6.3 = INTEGER: 0
.1.3.6.1.2.1.25.2.3.1.6.4 = INTEGER: 500757557 # Is this the current size?
If so, what format and how do I get this into MRTG format? (2)
.1.3.6.1.2.1.25.2.3.1.6.5 = INTEGER: 846031
.1.3.6.1.2.1.25.2.3.1.6.6 = INTEGER: 0

(1) This value does not match the byte size that is listed in the Win2k
drive properites.
(2) same as (1)

----------------------------------------------------------------------------

MRTG Output:

The MRTG output is this (without the graph)

MAX: 1920.4 G Bytes (0.1%)  Average 1904.9 G Bytes (0.1%)  Current 1920.4 G
Bytes (0.1%)

Total drive size is 1.87 Terabytes. It is about 99% full right now. 
----------------------------------------------------------------------------

I would also like to add to the graph a static line at say 70% of total
drive space. I would also like the graph to go no higher than the max size
of the drive and have this graph as static. In other words, the graph will
always show 0 - (max drive size).

I have been working on this for two weeks. I have learned alot but my head
hurts. 

Thanks,
Austin Wolfe
