The ltsv parser plugin parses LTSV format.

Parameters

See Parse Section Configurations.

delimiter

The delimiter (character or string) separating LTSV values.

delimiter_pattern

The delimiter pattern of TSV values. This parameter overwrites delimiter parameter if specified.

delimiter_pattern is string type before 1.2.0.

label_delimiter

The delimiter character between field name and value.

Example for LTSV

This incoming event:

time:2013/02/28 12:00:00\thost:192.168.0.1\treq_id:111\tuser:-

is parsed as:

time:
1362020400 (2013/02/28/ 12:00:00)
​
record:
{
  "host"   : "192.168.0.1",
  "req_id" : "111",
  "user"   : "-"
}

If you set null_value_pattern '-' in the configuration, user field becomes nil instead of "-".

Example with delimiter_pattern

With this configuration:

<parse>
  @type ltsv
  delimiter_pattern /\s+/
  label_delimiter =
</parse>

This incoming event:

timestamp=1362020400 host=192.168.0.1  req_id=111 user=-

is parsed as:

record:
{
  "timestamp": "1362020400",
  "host"     : "192.168.0.1",
  "req_id"   : "111",
  "user"     : "-"
}
