top and rds CPU usage

Bernhard Mueller — Thu, 17 Jul 2003 12:11:15 GMT

After upgrading to DP5.0 I notices the rds process of OmniBack is always #1 in top with values of %WCPU and %CPU of 65-70% for this process.

However, above, in the CPU states section I see both CPUs at 90% idle most of the time.

I *believe* the process related percentage is only a rough estimation but how could it differ that much?

Regards,
Bernhard

Hi,
in this case i think of a patch for top.
What OS do you have ?

And, just for comparison, what is the output of a

sar 3 10

?

I trust more sar than top...

HTH,
Massimo

Bernhard,

this is due to a bug in the 'top' command. HP is aware of it and a patch for it will appear.

You can verify it by installing a trial version of GlancePlus. You'll notice than that the rds daemon is not consuming the amount of cpu that top is telling you.

regards,

Kurt

Hi folks,

that's what I had suspected meanwhile...

I do have 11.0 and PHCO_26020 (latest top cumulative)

first thing I did was use sar 1 100 (much to my relief!)

glance supports the impression that it's top
which is wrong.

Thank you anyway for the quick answers.

Regards,
Bernhard
