List of SYNTAX for logstash's grok

Question

The syntax for a grok pattern is %{SYNTAX:SEMANTIC}. How do i generate a list of all available SYNTAX keywords ? I know that I can use the grok debugger to discover patterns from text. But is there a list which i can scan through?

Answer 1

They are in GIT and included somewhere in the distribution. But it's probably just easiest to view it online:

Answer 2

The grok patterns files are now in the logstash-patterns-core repository. Assuming you have a clone of it in the logstash-patterns-core directory on your filesystem, you can issue a command like this one to list all SYNTAX keywords:

$ find ./logstash-patterns-core/patterns -type f -exec awk '{print $1}' {} \; | grep "^[^#\ ]" | sort

As of commit 6655856, the output of the command (aka the list of SYNTAX keywords) looks like this (remember though that this list is not static):

Answer 3

If you have installed Logstash as a package, they can be found at /opt/logstash/patterns/grok-patterns.

Answer 4

You can view using these commands:

# find / -name patterns

/opt/logstash/vendor/bundle/jruby/1.9/gems/logstash-patterns-core-2.0.5/patterns

/opt/logstash/vendor/bundle/jruby/1.9/gems/logstash-patterns-core-2.0.5/lib/logstash/patterns

Just browse to the directory

# cd  /opt/logstash/vendor/bundle/jruby/1.9/gems/logstash-patterns-core-2.0.5/patterns

And here you have a whole list of patterns

aws                   exim                  haproxy            
linux-syslog          mongodb               rails
bacula                firewalls             java                  mcollective           nagios                redis
bro                   grok-patterns         junos                 mcollective-patterns  postgresql            ruby
