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?

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"
