I'm using Grok Constructor and it has 13 different "grok patterns" listed and all checked by default, e.g. "firewalls". So far I've been unchecking all of them except for "grok-patterns" not being sure the others were available. Are they all installed by default?
Look under $LS_HOME/vendor/bundle/jruby/1.9/gems/logstash-patterns-core-<version>/patterns/
firewalls should be there
Yes I see they are all there plus a couple extras not used by Grok Constructor. Thanks!
