# 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 by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.fluentbit.io/manual/2.1/pipeline/parsers/logfmt.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
