[mrtg] Re: CPU monitoring on Xylan switch....again.

[Jeff Meisner]

Unfortunately, the Xylan CPU Utilization is an OCTET STRING, and MRTG cannot
interpret this properly
I had to write a small perl script to do extract the values from the octet
string and then feed it to MRTG.

Hi !
Well here I go again:
I am trying to get somthing usefull out of this mibstring :
The switch is a omniswitch5.

.iso.org.dod.internet.private.enterprises.xylan.xylanArch.xylanHealthArch.he
althDeviceInfo.healthDeviceCpuData

Device-level cpu utilization information.
       Octet 0: average cpu #1 utilization over the latest sample period
(percent)
       Octet 1: average cpu #1 utilization over the latest minute (percent)
       Octet 2: average cpu #1 utilization over the latest hour (percent)
       Octet 3: maximum cpu #1 utilization over the latest hour (percent)
       Octet 4: average cpu #2 utilization over the latest sample period
(percent)
       Octet 5: average cpu #2 utilization over the latest minute (percent)
       Octet 6: average cpu #2 utilization over the latest hour (percent)
       Octet 7: maximum cpu #2 utilization over the latest hour (percent)
       Octet 8: average cpu #3 utilization over the latest sample period
(percent)
       Octet 9: average cpu #3 utilization over the latest minute (percent)
       Octet 10: average cpu #3 utilization over the latest hour (percent)
       Octet 11: maximum cpu #3 utilization over the latest hour (percent)
       Octet 12: average cpu #4 utilization over the latest sample period
(percent)
       Octet 13: average cpu #4 utilization over the latest minute
(percent)
       Octet 14: average cpu #4 utilization over the latest hour (percent)
       Octet 15: maximum cpu #4 utilization over the latest hour (percent).

>From Getif I get :
.iso.org.dod.internet.private.enterprises.xylan.xylanArch.xylanHealthArch.he
althDeviceInfo.healthDeviceCpuData.0

:1617181E000000000000000000000000

But no data are saved in the log file, what am I dooing wrong??

My .cfg file looks like this:

Target[router2.cpu]:1.3.6.1.4.1.800.2.18.1.15.0&1.3.6.1.4.1.800.2.18.1.11.0:

MaxBytes2[router2.cpu]:100

Title[router2.cpu]: Testswitch CPU Usage
PageTop[router2.cpu]: <H1> TestSwitch Free Memory and CPU Usage </H1>
WithPeak[router2.cpu]:w
YLegend[router2.cpu]: Memory/CPU

LegendI[router2.cpu]: &nbsp;Memory:

I have tied many different option settings
