diagmond performance hit every 290 secs

nothing is set at this interval, but a major perf hit every 290 secs. default ioscan is turned to off. 1 what is responsible for this & 2 what are the ramifications if I turn diagnostics off? PS this will affect about 3000 systems worldwide.....

Maybe you are running a bad and already replaced version?

Hi

Since 10.20 I've been answering DBA's questions about diagmond consuming, typically 5% of overall CPU consumption. On a big box with a big database 5% is a big hit.

You can turn off diags through /sbin/init.d/diagnostics off, and this will regain you resources. But I would not do it. Instead I would look to update my firmware and diagnostics bundles and review the problem.

For its possible if your diags are out of date that your firmware is trying to send a message and no one is listening: Diagnistics software does the listening. Firmware does the sending.

So if your firmware is out of date, you may have a problem and firmware can't notify anyone because it doesn't know how to.

STM version should be A.65.00 (B.11.11.21.06 in swlist), EMS A.04.20.11

Can you confirm?

resolved. it was tied to the RAD process for olar/r under diagmond control. Thanks everyone for your help
