Logrotate Script Error

Hey guys,

I’m trying to rotate a logstash log that can grow pretty large. 3.4GB last I saw!

And that’s because the logrotate script I came up with didn’t work.

The error I get on a syntax check is this:

#logrotate -f logstash size: ‘100M’: No such file size: ‘100M’: No such file size: ‘100M’: No such file size: ‘100M’: No such file size: ‘100M’: No such file size: ‘100M’: No such file size: ‘100M’: No such file size: ‘100M’: No such file

And this is the logstash rotate script:

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

I can’t find the error there. Can I have a suggestion as to what’s wrong and how to correct it?

Thanks, Tim

  • Multiple errors here, first hint: “man 8 logrotate” is a good start.

    Second: wrong order of lines:
    diff -U2
    [code]
    — your logstash-rotate
    +++ corrected logstash-rotate
    @@ -7,6 +7,7 @@
    missingok
    notifempty
    – postrotate
    size 100M
    + sharedscripts
    + postrotate
    /bin/kill -HUP `cat /var/run/logstash.pid 2>/dev/null` 2> /dev/null || true
    endscript
    [/code]

    In short: “postrotate” line is in wrong position, add line “sharedscripts”

  • 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!
