I would be interested in this as well. Right now I am using a PERL
script in conjunction with MRTG to graph our CPU usage. The script uses
telnet to pull the current CPU usage from the WiSMs.
I am willing to share this, but it does require the Net::Telnet::Cisco
PERL module to be installed.

On a somewhat related note, does anyone have the SNMP OIDs to monitor
the CPU load on the WiSM?

We have always run under 5% for the most part (occasional spikes that
rarely approach 50%), with 12 WiSMs, 1600 APs and thousands and
thousands of users on multiple WLANs. But- we keep ALL APs, WiSMs, WCS,
and loc servers in a private management VLAN that is heavily protected.
Not sure if this has a bearing. This has always been the case (low CPU),
across multiple code versions.
That being said- we have had just about every other problem associated
with the WiSMs and or WCS that you can imagine. Has been challenging, to
say the least.

Hi All,
A quick question for those out there with WISMs... What level of
CPU usage are you experiencing (with how many users)?
A bit of background...
We have two wism blades (4 wisms) and since we purchased them in
about april'07 they were running at about 35%, rising to 50% at peak
times, with frequent spikes up to about 90%. The spikes were
worrying, but the average seemed ok, and as they did this from day
one I was under the impression this was the norm.
Recently, we upgraded to the 4.2.x.y stream from 4.1. As has been
covered in other recent posts, 4.2 has some outstanding issues (more
than others anyway) and things became unstable... so we decided to go
back to 4.1.85.0 (TAC hasn't provided us with any solutions for 4.2
issues). We had a backup of our previous 4.1 config, but I chose not
to use it and start again from scratch (a few things had changed, so
either way involved work)
Since the reversion to 4.1.85.0, our cpu usage now averages 2% and
peaks at 6% at peak times (220 waps, ~350 users).
[4.1.85.0, 12.2(18)SXF7]
Thanks,
James
