We are receiving frequent (every 5 minutes) messages on couple of our proliant servers running Linux OS.The /var/log/messages file is filled with lines similar to the following:
Oct 5 11:45:01 ALG-NBUMEDIA01 /usr/sbin/cron[21605]: (root) CMD ( /opt/hp/hp-health/bin/check-for-restart-requests).
Can anyone tell me whats its mean.how can i avoid this messages in log file.
Your cron daemon is running the script /opt/hp/hp-health/bin/check-for-restart-requests, as specified in file /etc/cron.d/hp-health. This file was installed as part of the hp-health package.
(Older versions of hp-health did not have this; it seems to have been introduced in one of the newer versions.)
You can change syslog configuration to send all log messages to a different file. For example, in RHEL 5.x, the syslog configuration for /var/log/messages is: *.info;mail.none;authpriv.none;cron.none /var/log/messages
And the cron log messages are stored into a different file: cron.* /var/log/cron
Once the cron log messages are in a different file, you can set a shorter log rotation schedule for them if you feel it's appropriate. Or if you want to store _some_ cron job messages but not these, you'll have to add a post-processing step to your log rotation procedures to filter these messages out before archiving the log for long-term storage.
