# Captures are a slightly modified version of logstash "grok" patterns, with
|
||
|
|
# the format %{<capture syntax>[:<semantic name>][:<modifier>]}
|
||
|
|
# By default all named captures are converted into string fields.
|
||
|
|
# Modifiers can be used to convert captures to other types or tags.
|
||
|
|
# Timestamp modifiers can be used to convert captures to the timestamp of the
|
||
|
|
# parsed metric.

# View logstash grok pattern docs here:

# All default logstash patterns are supported, these can be viewed here:

# Available modifiers:
|
||
|
|
# string (default if nothing is specified)
|
||
|
|
# int
|
||
|
|
# float
|
||
|
|
# duration (ie, 5.23ms gets converted to int nanoseconds)
|
||
|
|
# tag (converts the field into a tag)
|
||
|
|
# drop (drops the field completely)
|

|
# Timestamp modifiers:

# Example log file pattern, example log looks like this:

# Breakdown of the DURATION pattern below:
|
||
|
|
# NUMBER is a builtin logstash grok pattern matching float & int numbers.
|
||
|
|
# [nuµm]? is a regex specifying 0 or 1 of the characters within brackets.
|
||
|
|
# s is also regex, this pattern must end in "s".
|
||
|
|
# so DURATION will match something like '5.324ms' or '6.1µs' or '10s'
