By the way, it's not a monitoring tool because the spikes disappear right after
the backup window...

Subject: Re: TSM 7.1.7 server CPU behavior
Hi Eric,
I only have sar data of last night but I see a load around 40% that breaks down
to 15% user, 5% system 10-20% iowait and the rest being idle.
10% is very low, it must be overpowered or still running a very low load.
Maybe it's a monitoring tool that is hitting the system every 5 minutes, do you
see entries in the activity log that match the load? do you seen more iop/s on
the database?
