CentOS, Grsync/Rsync logging or alerting on failures

  • 772

I have a CentOS 5.5 x64 server that mirrors a NetGear ReadyNAS Everynight at midnight using rsync. I need a way to be alerted if the backups fail.

I have this in my users cron. It does run and works fine.

0 0 * * * /usr/bin/grsync-batch -f /home/user/jobname.grsync 2>&1 > /home/user/logfile

I do not run rsync as a daemon, so I do not think I can specify a syslog. I have a managed systems server that can watch for SNMP alerts and syslogs events if I know what error to tell it to look for. I monitor my mail server by checking if postfix and amavis are running and accepting connections and if not I run 'logger -p mail.info 'whatever error here' and then the Monitor server checks the log every hour and if that is in there, it alerts everyone. It would be OK if I could do something like that in a script.

How does everyone else alert themselves when rsync encounters an error?

Thanks,

rsync

    Create a shell script to be called by cron. Within that shell script, place the grsync-batch command (along with options)....

    grsync-batch ... > logfile 2>&1
if [ "$?" -ne "0" ]; then
     mail -s "rsync error" [email protected] < logfile
fi

    $? is the exit code of the last command. 0 usually means success and anything else means an error occured.

    rsync man page (exit values at the bottom)
