Trim system log file

[Wantit Tangrugsasut]

Hi,

I use HP/UX 9000 and I ran to file system problem. I think the size is getting too big.

Please suggest how to trim system log file
or anyway to free up some disk space

Thank You,

Wantit

Hi, try this little script:
#!/usr/bin/sh
##
###

syslog=/var/adm/syslog/syslog.log



cp -p$syslog /var/adm/syslog/syslog.log.$(date +%m%d%y)
> $syslog

Then what I usually do is gzip the backed up syslog file and this saves a lot of space. Hope this helps.

In SAM there is an option where you can look at all the system files. This will show the size, and maximum size (although it will go over this), and the percentage full. Some of the logs will be over 100%. You can change the max size and also use SAM to trim the file to whatever you want (to 0, to 10% of max, whatever). This is hepful since you can see all the logs and so you can get an idea for the ones that will get out of hand.

You can trim the following files/log files to zero as follows:
cat /dev/null > /var/adm/syslog/syslog.log
cat /dev/null > /var/adm/wtmp
cat /dev/null > /var/adm/wtmp
Remove the files in /var/adm/preserve (Ex*)

Also you can use the cleanup command to remove old patches. (cleanup -F)

Hi, Mark

Thanks for your reply

You said "use SAM to trim the file"

Did you talk about freedisk in Find and Remove Unused Filesets or you mean something else?

How can you trim the file in SAM?

In SAM, go to routine tasks, system log files, and select the trim the file option.

You can trim to zero or a selected KB size.

Hi, Chris

Is it safe to set those files to empty?

Is cleanup command available in hp/ux 10.2?

Cleanup patch utility is available on 10.20. You can reduce the files if you don't have any security check on the wtmp and btmp.
