Logfmt

The logfmt parser lets you parse data in the logfmt format.

Here is an example parsers configuration:

parsers.yaml

parsers:
  - name: logfmt
    format: logfmt

parsers.conf

The following log entry is valid for the previously defined parser:

key1=val1 key2=val2 key3

After processing, its internal representation will be:

[1540936693, {"key1"=>"val1",
              "key2"=>"val2"
              "key3"=>true}]

If you want to be more strict than the logfmt standard and not parse lines where certain keys lack values (such as key3 in the previous example), you can configure the parser as follows:

parsers.yaml

parsers:
  - name: logfmt
    format: logfmt
    logfmt_no_bare_keys: true

parsers.conf
