System Log Files - What information do they contain and how useful they can be?

Hi_This_is_Dev · 09-20-2010, 10:26 PM

Hi,

[1] What log files in /var/logs can we safely delete to free up hard-disk space?

[2] System reports "Disk-Controller Failure" then which log files in /var/logs should we check?

/var/log/kern.log

/var/log/boot.log

or some other log files, and also how to diagnose / rectify that problem / error?

Please Note: I am using RHEL 5.x and AIX 5.x.

Depend on you.

Where did you see this error?

To answer the first question, I exactly said "It depends on you."

About the second question... I don't know. They asked me those questions in an interview yesterday.

I have mentioned these files here:

/var/log/kern.log

/var/log/boot.log

to ask you if they should be checked. I said, "dmesg" could be helpful.
