Haystack now supports structured logging out-of-the box.
|
||
|
|
Logging can be separated into 3 categories:
|
||
|
|
- If [`structlog`](https://www.structlog.org/en/stable/) is not installed, Haystack will
|
||
|
|
use the standard Python logging library with whatever configuration is present.
|
||
|
|
- If `structlog` is installed, Haystack will log through [`structlog`](https://www.structlog.org/en/stable/) using
|
||
|
|
structlog's console renderer.
|
||
|
|
To disable structlog, set the environment variable `HAYSTACK_LOGGING_IGNORE_STRUCTLOG_ENV_VAR` to `true`.
|
||
|
|
- To log in JSON, install [`structlog`](https://www.structlog.org/en/stable/) and
|
||
|
|
- set the environment variable `HAYSTACK_LOGGING_JSON` to `true` or
|
||
|
|
- enable JSON logging from Python
|
||
|
|
```python
|
||
|
|
import haystack.logging
|
||
|
|
|
||
|
|
haystack.logging.configure_logging(use_json=True)
|
||
|
|
```
