EMS monitoring is a place that produces messages that can run into a script to gather potential problem information. Depending on your configuration of EMS can be where information is sent. 'root's mail is good place to look, other than in /etc/resmon/lbin/monconfig.

/var/adm/syslog/syslog.log

dmesg

GSP logs from your system console

I feel you should familiarize yourself with EMS (Event Monitoring Services) as well. It's part of the Online Diagnostic Bundle. I would recommend reading this EMS whitepaper.

A quick and easy command to use would be dmesg.

Run the command #dmesg every now and again to view the contents of the diagnostic message buffer. A normal output will show you boot up info ending in a description of memory.

What you may see logged here are SCSI errors, single bit errors (logged as LPMC's).

Run # man dmesg for more info.

find out if your system has Support Tools loaded. (All machines with HP-UX 11.x have to have this software loaded). Then use the following commands:

#mstm - texted-based
#xstm - graphics based.

Manuals to use this software are available at docs.hp.com in pdf format. This software will allow you to run diagnostics on all components of your system, plus it will monitor your system and notify you of any potential problems. The software is on the Support + CD of your software bundle, if it is not installed on your system already.
