[mrtg] Re: Disk Utilization by percent

[Daniel Curry]

Will,
	I am grabbing the same stats from a digital unix box.  when I attempted
to use the snmp for this data I found it lacking, but by having an rsh
session exec a script, the system did the percents for me.  I just
grepped the lines I needed and returned them to mrtg.

I hope this helps.  If you figure out a way to do this for memory and
swap, let me know!

Subject: [mrtg] Disk Utilization by percent


	I am trying to graph the percent of disk usage on a solaris machine.  I
am 
using the host resource mib to grab disk usage and size.  my problem is 
this: I need to divide the used by the max size and multiply by 100.
What 
would the syntax for this be?  I tried:

Target[disk]: hrStorUsed&hrStorSize:public at 1.1.1.1 /
	      hrStorUsed&hrStorSize:public at 1.1.1.1 * 100

This does not return the expected value.  I attempted to graph 
hrStorUsed&hrStorSize and let MRTG calculate percents, but once I
converted 
the kb to bytes, I exceeded the maximum integer on the machine!
Because I am running MRTG remotely, I'll need to get this via snmp
(rather 
than a local script or remote exec).

How are other people doing large disk (8-30+ GB) monitoring using MRTG?

Thanks!

Will
