## Overview

NOTE - This processor is experimental, with the intention that its functionality will be reimplemented in the [transform processor](../transformprocessor/README.md) in the future.
For this reason, the processor is not included in the `contrib` distribution.

The logs transform processor can be used to apply [log operators](../../pkg/stanza/docs/operators) to logs coming from any receiver.
Please refer to [config.go](https://github.com/open-telemetry/opentelemetry-collector-contrib/tree/main/processor/logstransformprocessor/config.go) for the config spec.

Examples:

```yaml theme={null}
processors:
  logstransform:
    operators:
      - type: regex_parser
        regex: '^(?P<time>\d{4}-\d{2}-\d{2}) (?P<sev>[A-Z]*) (?P<msg>.*)$'
        timestamp:
          parse_from: body.time
          layout: "%Y-%m-%d"
        severity:
          parse_from: body.sev
```

Refer to [config.yaml](https://github.com/open-telemetry/opentelemetry-collector-contrib/tree/main/processor/logstransformprocessor/testdata/config.yaml) for detailed
examples on using the processor.

## Configuration

### Example Configuration
