Hello,

You could start with the command top to
see what processes take the most of your cpu.

If this does not give you any clue you could
try glance.

Hi Juno,

Suggest you have a look at the two system admin postings. Thse have an abundance of scripts that can be utilised for a variety of things including some automated system check routines. Some of them quite quite good.

There are three tools basically utilised to check processes. These are top/glance/ps

There are several things that can be check several times a day.

Backup success/failure
Filesystem space monitoring/growth
CPU utilisation, you can use top/glance/sar
Swap utilisation, swapinfo/glance
log file entries. mail/syslog/EMS events/security files, last/lastb

HTH

Use top to see which process is using a lot of CPU time..

Also check if you have zombi processes.. ps -efl | more

Other isseus might be hardware: How much RAM you've got?

What cpu speed.. ??

A netstat -s will show you network packet statistics, may help in seeing if you get many connection drops or timeouts or other network related issues.
