How to do log rotation in HP-UX?

I would like to log rotation for every month.

I knew that log will be rotated for every reboot, therefore one file with extention of .old will be created.

But I would like to log rotation for every month. So I need one log file for one month.

Re: How to do log rotation in HP-UX?

Hi:

There is an old 'logrotate' utility at the HP-UX Porting Centre which you would have to compile yourself.

That said, you don't offer which HP-UX operating system versions you're using nor *which* logs you want kept monthly.

All this said, you could cruft a simple script (and schedule that from 'cron') that would call the standard startup/shutdown scripts like '/sbin/init.d/syslogd' to close and open a new logfile. Your script would then conclude its action by renaming the "OLD*" logfile to one with the month name.

Regards!

creata a cron job to run every month to
restart the syslogd deamon by
/sbin/init.d/syslogd stop
/sbin/init.d/syslogd start

Senthil,

Check this out: Logrotate Management tool:
Logrotate is designed to ease administration of systems that generate large numbers of log files. It allows automatic rotation, compression, removal, and mailing of log files. Each log file may be handled daily, weekly, monthly, or when it grows too large.

http://hpux.connect.org.uk/hppd/hpux/Sysadmin/logrotate-2.5/

This is quite old tool, but you can try it out,







You can also find simple shell script or perl script that help to rotate the log:



Ex: (Change the logfile path for hp-ux to /var/adm/syslog/syslog.log )
------
## Configuration for logrotate
# Please read perl-logrotate.pl for more information

logfile /var/log/messages

rotate-time 1 week
keep-files 5
compress yes
status-file /var/cache/logrotate.status
dryrun yes
