CPU Utilization

[Wanda_5]

hi everyone,

How can i view CPU utilization of my HP Procurve 4108GL switch? and what is the acceptable threshold?

thanks.

Wanda,
Not sure how far you want to go with the CPU stats, or how you want to look at them.

I don't have a 4108 to look at but think that most of the console menus would be close to the same. If you just want to have a peek, the console menu "General System Information" under "Status and Counters" would give it to you. If you wanted to monitor it with some SNMP utility, you would want to use a MIB browser to find the OID. Start by downloading the mibs-nov03.exe and compiling them for use with your fav browser.

Hard to answer what is acceptable... anything less than 100% for sure but it really depends on the dynamics of your network. Something like that should have been baselined from the start.

hi les,

viewing port counters only tells me the total packets but not in percentage form.. how will i know that i am currently on lets say 90% utilization already? in addition, it tells us the usage per port. is there something like the CPU usage of the switch itself?

thanks again!

Like I said, I don't have a 4108gl to look at but assumed all menus would be pretty much the same. Looking at one of my 5308xl switches I see:

As you can see, my CPU is at 1%. Unfortunately the lines wrap so you cannot see the sceen the way it shows in telnet.

Thanks Les, I also found that out just a while ago. nonetheless, thanks for your help. Very much appreciated!

by the way, for future reference, for 4108GL that is under system information.
at CLI, just type show system-information.. and thats it!

Had the same solution as Les.. and it works both ways.. Les' solution is also true for 4108.. just a matter of preference.
