General Grok Patterns

USER

%{USERNAME}

USERNAME

[a-zA-Z0-9._-]+

BASE10NUM

(?<![0-9.+-])(?>[+-]?(?:(?:[0-9]+(?:\.[0-9]+)?)|(?:\.[0-9]+)))

BASE16FLOAT

\b(?<![0-9A-Fa-f.])(?:[+-]?(?:0x)?(?:(?:[0-9A-Fa-f]+(?:\.[0-9A-Fa-f]*)?)|(?:\.[0-9A-Fa-f]+)))\b

INT

(?:[+-]?(?:[0-9]+))

NONNEGINT

\b(?:[0-9]+)\b

NUMBER

(?:%{BASE10NUM}) BASE16NUM (?<![0-9A-Fa-f])(?:[+-]?(?:0x)?(?:[0-9A-Fa-f]+))

POSINT

\b(?:[1-9][0-9]*)\b

WORD

\b\w+\b

NOTSPACE

\S+

SPACE

\s*

DATA

.*?

GREEDYDATA

.*

QUOTEDSTRING

(?>(?<!\\)(?>"(?>\\.|[^\\"]+)+"|""|(?>'(?>\\.|[^\\']+)+')|''|(?>`(?>\\.|[^\\`]+)+`)|``))

UUID

[A-Fa-f0-9]{8}-(?:[A-Fa-f0-9]{4}-){3}[A-Fa-f0-9]{12}

Date and Time Grok Patterns

MONTH

\b(?:Jan(?:uary)?|Feb(?:ruary)?|Mar(?:ch)?|Apr(?:il)?|May|Jun(?:e)?|Jul(?:y)?|Aug(?:ust)?|Sep(?:tember)?|Oct(?:ober)?|Nov(?:ember)?|Dec(?:ember)?)\b

MONTHNUM

(?:0?[1-9]|1[0-2])

MONTHNUM2

(?:0[1-9]|1[0-2])

MONTHDAY

SECOND

(?:(?:[0-5]?[0-9]|60)(?:[:.,][0-9]+)?) TIME (?!<[0-9])%{HOUR}:%{MINUTE}(?::%{SECOND})(?![0-9])

Note: 60 is a leap second in most time standards.

DATE

%{DATE_US}|%{DATE_EU}

DATESTAMP

%{DATE}[- ]%{TIME}

DATESTAMP_RFC822

%{DAY} %{MONTH} %{MONTHDAY} %{YEAR} %{TIME} %{TZ}

DATESTAMP_RFC2822

%{DAY}, %{MONTHDAY} %{MONTH} %{YEAR} %{TIME} %{ISO8601_TIMEZONE}

DATESTAMP_OTHER

%{DAY} %{MONTH} %{MONTHDAY} %{TIME} %{TZ} %{YEAR}

DATESTAMP_EVENTLOG

Java Grok Patterns

(?:[a-zA-Z$_][a-zA-Z$_0-9]*\.)*[a-zA-Z$_][a-zA-Z$_0-9]*

JAVAFILE

(?:[A-Za-z0-9_. -]+)

A space character is allowed to match special cases, such as Native Method or Unknown Source.

JAVAMETHOD

(?:(<init>)|[a-zA-Z$_][a-zA-Z$_0-9]*)

JAVASTACKTRACEPART

%{SPACE}at %{JAVACLASS:class}\.%{JAVAMETHOD:method}\(%{JAVAFILE:file}(?::%{NUMBER:line})?\)

The line number is optional in special cases, such as Native Method or Unknown Source.
