HP-UX 11i Log File Management with Logrotate

1. Dusan Baljevic

By default, HP-UX does not have any global tool to manage log file archiving and rotation. A
good, open-source option is to use logrotate.
a) Go to:
http://hpux.connect.org.uk/hppd/hpux/Sysadmin/logrotate-3.8.7/
Install it on HP-UX server (and all prerequisites).
b) Set up a cron job. For example:
# crontab -l
# Entry for monitoring status of the EMSHAProvider
5,20,35,50 * * * * /etc/opt/resmon/lbin/mon_EMSHAProvider_state.sh
5,20,35,50 * * * * /opt/sfm/bin/restart_sfm.sh
10,20,30,40,50 * * * * /usr/sbin/dmesg - >> /var/adm/messages # Entry for vacuuming the CERDB
5 1 * * * /opt/psb/vacuum
5,20,35,50 * * * * /opt/raidsaprovider/bin/restart_raidsaprovider.sh
5,20,35,50 * * * * /opt/sas/provider/bin/restart_sasprovider.sh
5,20,35,50 * * * * /opt/fcprovider/bin/restart_fcprovider.sh
5,20,35,50 * * * * /opt/dasprovider/bin/restart_dasprovider.sh
5,20,35,50 * * * * /opt/psb/bin/restart_logserv.sh
# logrotate
0 0 * * * /usr/local/sbin/logrotate /etc/logrotate.conf>/var/adm/syslog/logrotate.log 2>&1
c) Set up the /etc/logrotate.conf. For example:
# cat /etc/logrotate.conf
# sample logrotate configuration file
compress
/var/adm/syslog/syslog.log {
rotate 5
weekly
postrotate
/usr/bin/kill -HUP `cat /var/run/syslog.pid`
endscript
}
/var/adm/syslog/mail.log {
rotate 5
weekly
postrotate
/usr/bin/kill -HUP `cat /var/run/syslog.pid`
endscript
}

2. /var/adm/syslog/vseassist.log {
rotate 12
monthly
missingok
}
/var/adm/sw/swverify.log {
rotate 5
weekly
postrotate
/sbin/init.d/swagentd stop
/sbin/init.d/swagentd start
endscript
}
#/var/log/httpd/access.log {
# rotate 5
# mail root
# size 100k
# sharedscripts
# postrotate
#
/usr/bin/killall -HUP httpd
# endscript
#}
# no packages own wtmp -- we'll rotate them here /var/adm/wtmp {
monthly
create 0664 adm adm
rotate 12
}
/var/adm/wtmps {
monthly
create 0664 adm adm
rotate 12
}
/var/opt/wbem/*.log {
monthly
rotate 2
olddir /var/opt/wbem/prevmonth
missingok
postrotate
/sbin/init.d/cim_server stop
/sbin/init.d/cim_server start
endscript
nocompress
}

3. d) Check how it works:
# cat /var/run/logrotate.status
logrotate state -- version 2
