The logfmt parser allows to parse the logfmt format described in https://brandur.org/logfmt . A more formal description is in https://godoc.org/github.com/kr/logfmt .

Here is an example configuration:

[PARSER]
    Name        logfmt
    Format      logfmt

The following log entry is a valid content for the parser defined above:

key1=val1 key2=val2 key3

After processing, it 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 some attributes do not have values (such as key3) in the example above, you can configure the parser as follows:

[PARSER]
    Name        logfmt
    Format      logfmt
    Logfmt_No_Bare_Keys true
