Hi, Samir. This is a symptom of the daylight savings time change the USA implemented back on March 14th, 2010 (about a month ago...). Moving the system clock forward (or backward in the fall) confuses PerfKit as to what time it really is, and it produces history files that contain only an hour's worth of data.
The easiest fix is simply to log off and then restart PERFSVM. I think it would bve a good idea if IBM put a note someplace in the PERFSVM documentation that it does not handle daylight savings changes properly and needs to be recycled when such changes are made. Hope this helps. Have a good one. On 04/19/2010 08:32 AM, Samir Reddahi wrote:
New question: I've noticed that since about a month the ACUM HISTSUM contains 1 record per day ( at 23:00:00) instead of the usual 1 record an hour. I haven't changed anything in the perfkit for a long time. Is there a command that can change this back to an hourly average? I've checked the perfkit guide and the reference, but can't find it.
