Grok Patterns

Below we list predefined Grok patterns that you can use with the Grok parser. The patterns are grouped by the kinds of files in which they occur.

Solr

HANDLER %{WORD}.%{WORD}.%{WORD}.%{WORD}.%{WORD}
SOLR_QUERY \[collection%{NUMBER:collection}\]\s+webapp=/%{WORD:webapp}\s+path=/%{WORD:path}\s+params=\{%{GREEDYDATA:params}\}\s+hits=%{NUMBER:hits}\s+status=%{NUMBER:status}\s+QTime=%{NUMBER:QTime}
SOLR_LOG %{LOGLEVEL}\s+-\s%{TIMESTAMP_ISO8601};\s%{JAVACLASS};\s+%{MESSAGE:message}

SOLR_6_LOG4J %{TIMESTAMP_ISO8601:logdate} %{LOGLEVEL:level_s} \(%{DATA:thread_s}\) \[(?:%{DATA:mdc_s}| )\] %{DATA:category_s} %{JAVALOGMESSAGE:logmessage}
SOLR_6_REQUEST \[%{DATA:core_node_name_s}\] webapp=\/%{WORD:webapp_s} path=\/%{DATA:path_s} params=\{%{GREEDYDATA:params_s}\} hits=%{NUMBER:hits_i} status=%{NUMBER:status_i} QTime=%{NUMBER:qtime_i}

Ruby

RUBY_LOGLEVEL (?:DEBUG|FATAL|ERROR|WARN|INFO)
RUBY_LOGGER [DFEWI], \[%{TIMESTAMP_ISO8601:timestamp} #%{POSINT:pid}\] *%{RUBY_LOGLEVEL:loglevel} -- +%{DATA:progname}: %{GREEDYDATA:message}
REDISTIMESTAMP %{MONTHDAY} %{MONTH} %{TIME}
REDISLOG \[%{POSINT:pid}\] %{REDISTIMESTAMP:timestamp} \*

Rails

RUUID \h{32}
# rails controller with action
RCONTROLLER (?<controller>[^#]+)#(?<action>\w+)

# this will often be the only line:
RAILS3HEAD (?m)Started %{WORD:verb} "%{URIPATHPARAM:request}" for %{IPORHOST:clientip} at (?<timestamp>%{YEAR}-%{MONTHNUM}-%{MONTHDAY} %{HOUR}:%{MINUTE}:%{SECOND} %{ISO8601_TIMEZONE})
# for some a strange reason, params are stripped of {} - not sure that's a good idea.
RPROCESSING \W*Processing by %{RCONTROLLER} as (?<format>\S+)(?:\W*Parameters: {%{DATA:params}}\W*)?
RAILS3FOOT Completed %{NUMBER:response}%{DATA} in %{NUMBER:totalms}ms %{RAILS3PROFILE}%{GREEDYDATA}
RAILS3PROFILE (?:\(Views: %{NUMBER:viewms}ms \| ActiveRecord: %{NUMBER:activerecordms}ms|\(ActiveRecord: %{NUMBER:activerecordms}ms)?

# putting it all together
RAILS3 %{RAILS3HEAD}(?:%{RPROCESSING})?(?<context>(?:%{DATA}\n)*)(?:%{RAILS3FOOT})?

Postgressql

# Default postgresql pg_log format pattern
POSTGRESQL %{DATESTAMP:timestamp} %{TZ} %{DATA:user_id} %{GREEDYDATA:connection_id} %{POSINT:pid}
