Hi,

I have put the logstash.conf in the /etc/logstash folder and grok pattern in /etc/logstash/patterns folder

When I start the logstash server I get this error in the logstash.log

However

/opt/logstash/bin/logstash -f /etc/logstash/conf.d/logstash.conf --configtest
Configuration OK

I am a beginner and I am trying to use filebeat. Am I doing something wrong here ?

Where is MILTERENDOFMESSAGE supposed to be defined? When testing on http://grokconstructor.appspot.com/do/match the app throws this error:

This grok pattern has an unknown name MILTERENDOFMESSAGE : %{MILTERENDOFMESSAGE}

I was testing the %{PF} filter using some logs from mail.log I pasted in.

@athreyavc1

If you haven't figured it out yet, I'd suggest checking all files in the /etc/logstash/conf.d directory. Not just logstash.conf. Logstash concatnates all the files in there together. So if you're just testing one file, you won't be testing everything.

I think you can just do -f /etc/logstash/conf.d --configtest as well.

@jerrac

I've updated the above with the milter patterns.

@athreyavc1

You can put the patterns file anywhere. Then specify its location in the grok filter.

e.g.

        grok {
            patterns_dir => ["/home/logstash/config/patterns"]
            match => { "message" => ["%{PF}", "%{DOVECOT}" ] }
        }

This is defined twice and incorrect:

HELO (?:\[%{IP:helo}\]|%{HOST:helo}|%{DATA:helo})
It should be:
HELO (?:\[%{IP:helo}\]|%{HOSTNAME:helo}|%{DATA:helo})

Check the pattern file and see whether {HOST:helo} has been misspelt or not defined in the patterns file for that is where the error emanates from.

Postfix pattern causes error in latest Logstash:

HELO (?:[%{IP:helo}]|%{HOSTNAME:helo}|%{DATA:helo})

This was the cause of the error. Thanks.
