# Logfmt

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:

```python
[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:

```python
[PARSER]
    Name        logfmt
    Format      logfmt
    Logfmt_No_Bare_Keys true
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.fluentbit.io/manual/3.0/pipeline/parsers/logfmt.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
