# static\_labels

The static\_labels stage is an action stage that adds static-labels to the label set that is sent to Loki with the log entry.

## Schema

YAML ![Copy code to clipboard](/media/images/icons/icon-copy-small-2.svg) Copy

```yaml
static_labels:
  [ <string>: [<string>] ... ]
```

### Examples

For the given pipeline:

YAML ![Copy code to clipboard](/media/images/icons/icon-copy-small-2.svg) Copy

```yaml
- json:
    expressions:
      stream: stream
- labels:
    stream:
- static_labels:
    custom_key: custom_val
```

Given the following log line:

![Copy code to clipboard](/media/images/icons/icon-copy-small-2.svg) Copy

```none
{"log":"log message\n","stream":"stderr","time":"2019-04-30T02:12:41.8443515Z"}
```

The first stage would extract `stream` into the extracted map with a value of `stderr`. The `labels` stage would turn that key-value pair into a label. The `static_labels` stage would add the provided static labels into the label set.

The resulting entry that is sent to Loki will contain `stream="stderr"` and `custom_key="custom_val"` as labels.
