server health check

[Waugh]

Dear All,

Which points we need to consider for server health check. Can any suggest the checklist.

Regards,
Rkumar

Shalom,

Many use third party products like openview ITO or hobbit to monitor system health.

Check:
bdf # for full filesystems
swapinfo -tam # for excessive swap allocation
vmstat # for excessive paging
/var/adm/syslog/syslog.log # for relevant errors and hardware failures.

No mirror, no striping, just concatenation.

Run /usr/sbin/ioscan -fnk
to show HW status...

hi

u can grep from syslog as u needed

grep -i "crit" /var/adm/syslog.log

same u can do for

warn,temp,lbolt,failure.

for any hw error check in dmesg.

dmesg - shows the latest.

check /var/opt/resmon/log/event.log

regards

hi,

we used ISEE for HW problems, and when the HP stoped this services, we switched fully to the nagios.

we are able to monitor HW/OS/services....

Hi rkumar,

We also use nagios, this is an open source tool for monitoring. It is capable for monitoring almost anything that is scriptable. It has a lot of pre-defined plugins for many platforms. See here some example plugins for HP-UX:

Server Health Check :)

Most common report on all the unix projects :P

Ok BTW, as of i know, below parameters are considered for the Health Check Report

1) CPU (uptime)
2) mem utilization
3) FS utilization

rkumar,

A quick answer would be:
1. Check dmesg & /var/adm/syslog/syslog.log & /var/opt/resmon/event.log for any error or warnings.
1.1 : check system load: # uptime
2. check # bdf | grep vg00 # for any possible filesystem 100% alert.
3. check lan interfaces/ ping statistics // check GSP logs: PS , Chasis logs.
