New monitoring script on Xmonton - db_cpu.ksh

Hi all

Made some updates to the db_cpu script.
It can now cope with the situation where there are no databases running.
Previously, it would simply exit if it found nothing.
Now it reports it, and can trigger an alert if you configure it so.

Regards
Vernon

Hi all

I have updated this script to fix Andrey's reported bug.
I have also added an option to use sar for calculating %Idle, after Nick
reminded me that top is not part of a standard install.

Regards
Vernon

A good catch, and something I didn't consider.
All our databases instances have very different names, so the scenario
you describe just never occurred to me.
I will have a look at fixing this one when I get back to the office on
Tuesday. (Monday is a public holiday here)
However, if anybody wants to suggest a fix, or even update the code, go
for it.

Regards
Vernon

Good news.

Had reviewed the script. There may be one problem in that lines:
--
   for PROC in $(ps -efa | grep $DB | awk '{ print $2 }')

You do just grep, but imagine there may be instances like:
MYDB
MYDB1
MYDB12
or NOMYDB
So it will count MYDB numbers for MYDB1, MYDB12 and NOMYDB too

We should make grepping more intelligent, because oracle processes may
be listed like:
 ora_j000_MYDB
oracleMYDB (LOCAL=NO)
 ora_ckpt_MYDB
and so on

Hi all

I have just put something together to monitor Oracle database CPU usage.
