[CentOS] logrotate script error

[Tim Dunphy]

Hey!


That worked!

/var/log/logstash/* {
        daily
        rotate 7
        copytruncate
        compress
        delaycompress
        missingok
        notifempty
        size 100M
        sharedscripts
        postrotate
        /bin/kill -HUP `cat /var/run/logstash.pid 2>/dev/null` 2> /dev/null
|| true
        endscript
}

Thanks for the help!

Tim
