The best way is to get some form of management console, like VantagePoint or Patrol to handle this for you.

1. Can be done by monitoring a volume constantly
2. Can only be done by pinging from a different system - unless your power systems in your comms room are intelligent

HP openview
Vantage point operations can do great things more than the things you have mentioned.

The other way is to write scripts and use sendmail to send mails.

hi,

One simple way, will be to setup cron jobs to execute the monitoring scripts.
E.g.
crontab -l
#*******************************************************************************
# min|hour |day |month|day |script
# | |of mo| |of wk|
#----|-----|-----|-----|-----|--------------------------------------------------
#*******************************************************************************
5 * * * * /scripts/check.sh 1>/tmp/output.log 2>error.log

The check script should contain all the desired commands.

Hi,

you can use EMS (Event Monitoring System) to handle some triggy situation. With EMS there are several pre-configured monitors for your HW Subsystem...

for monitoring disk space : use HP OpenView if you have or write a shell script...

there are many threads in the forum..just search for "monitoring disk space" or something similar.

*don't* use the above cron line.

A basic principle of security. *never* put privileged user owned files in shared writable areas. This is a way to have any file trashed on you system by malicious users.

A better suggestions would be to have a private log area; eg:

mkdir -p /var/opt/admin/logs
chown -R root:admins /var/opt/admin
chmod -R 755 /var/opt/admin

Then have a cron like:
5 * * * * /scripts/check.sh 1>/var/opt/admin/logs/check.$(date +%Y%m%d%H%M) 2>error.log

We use BigBrother (http://bb4.com, free for non-commercial use) to monitor all manner of server parameters. Some scripts come standard, some were written here, and some from www.deadcat.net.

It's just a lot of shell scripts, but it works for us.

Here is a shell that I have at the end of my ".profile". In my case I login and out of my systems all day. This script displays the disks over 80% full and highlights the disks over 90%. Hope this helps. You could make some modifications and stick in CRON to keep a running log and/or send an email. Let me know if you can read the attachment, its my first attempt at it.
