From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.9) Gecko/20020313 Description of problem: When you use 'sar', 'iostat' or 'mpstat' on multiprocessor IA64 can the result show over 1000% usage. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1.execute 'sar', 'iostat' or 'mpstat' Actual Results: [root@azusa bin]# /usr/bin/mpstat Linux 2.4.7-nec1.2 (azusa) 04/24/2002 10:00:44 AM CPU %user %nice %system %idle intr/s 10:00:44 AM all 0.36 0.00 1.94 1021.70 64.27 As you can see is the idle over 1000% which is a bit much. Version is: [root@azusa bin]# /usr/bin/mpstat -V sysstat version 3.3.5 (C) S. Godard <sebastien.godard> As shipped with RH 7.1 Expected Results: When I compiled newer version myself did I get the real results. On Sebastien Godard's homepage is also mentioned lots of bugfixes for IA64 in newer version. http://perso.wanadoo.fr/sebastien.godard/ Saturday September 22nd, 2001 Sysstat 4.0.2 released (stable version). After a well deserved break, sysstat is back with its 4.0.2 version. This one includes a few bug fixes, in particular with IA64 machines, and new features like the database friendly option -H added to sar. Also the configuration procedure has been improved and sysstat is now translated into Norwegian. Translators are still wanted anyway (see note from Friday March 9th below)!

Godard <sebastien.godard> Additional info: This seems to affect RH7.2 as well, I have not tested it but the version of sysstat seems to old for RH7.2 also.
Is this still a problem with the version in RHL 7.2 (4.0.1-2)?
Yes. Bug occurs also in RHL7.2 (sysstat-4.0.1-2). [root@ds1 /root]# rpm -qf /usr/bin/mpstat sysstat-4.0.1-2 [root@ds1 /root]# mpstat -v sysstat version 4.0.1 (C) S.

Can you give 4.0.5-1 from http://people.redhat.com/teg/sysstat/ a try?
4.0.5-1 fixes the problem. 4.0.6-1 from http://perso.wanadoo.fr/sebastien.godard/ has another fix for SMP machines and mpstat. This would probably be useful for IA64 machines as most of these are SMP.
We're currently at 4.0.7
