Hi NetPro.

i have check with the monitoring administrator , he was mentioned must give him " MIB " . thus i am wondering where and how can i get this mib file for him ?

You can use RMON for this;

Something for cpmCPUTotalMonIntervalValue (OID

1.3.6.1.4.1.9.9.109.1.1.1.1.10) is probably what you want...


rmon event # log trap

description

owner


rmon alarm # .1.3.6.1.4.1.9.9.109.1.1.1.1.10.x absolute

rising-threshold xxxx falling-threshold xxxx owner


cpmCPUTotalMonIntervalValue OBJECT-TYPE

SYNTAX Gauge32 (0..100)

UNITS "percent"

MAX-ACCESS read-only

STATUS current

DESCRIPTION

"The overall CPU busy percentage in the last

cpmCPUMonInterval period.

This object deprecates the object cpmCPUTotal5secRev."

::= { cpmCPUTotalEntry 10 }

Hi Lavramov.


Good Day, would you mind to guide me the easiest way ? as i have tried out but don't seems to be work.


Switch Portion :

i want to monitor the CPU utilization if CPU hit to 30% - 50%. then it will trigger the alarm and send to Netview.


so, what should i configure into the Switch ? currently i have configured this to my switch but dont think it's work.


rmon event 1 log trap public description " CPU Util Above 30% " owner config

rmon event 2 log trap public description " CPU Util Below 50% " owner config

rmon alarm 1 lsystem.56.0 60 absolute rising-threshold 50 1 falling-threshold 30 2 owner config

rmon alarm 2 lsystem.8.0 60 absolute rising-threshold 480000000 falling-threshold 400000000 3 owner config


Your reply will be highly appreciated.
