vaultwarden logs only to [standard output](https://en.wikipedia.org/wiki/Standard_streams#Standard_output_(stdout)) (stdout) by default. You can also configure it to log to a file or Syslog.

When this environment variable is set, log messages will be logged to both stdout and the log file. If you're running in Docker, you'll most likely want to use a file path that is mounted from the Docker host (such as the `data` folder); otherwise, your log file will be lost (or at least hard to find) if the container is restarted or removed.
## Logging to Syslog
You can use Syslog with the `USE_SYSLOG` environment variable while alse setting `EXTENDED_LOGGING=true`:
```sh
docker run -d --name vaultwarden \
...
-e USE_SYSLOG=true -e EXTENDED_LOGGING=true \
...
```
When this environment variable is set, log messages will be logged to both stdout and Syslog.
## Changing the log level
To reduce the amount of log messages, you can set the log level to 'warn' (default is 'info'). The [Log level](https://docs.rs/log/0.4.7/log/enum.Level.html#variants) can be adjusted with the environment variable `LOG_LEVEL` while also setting `EXTENDED_LOGGING=true`. NOTE: Using the log level "warn" or "error" still allows [Fail2Ban](https://github.com/dani-garcia/vaultwarden/wiki/Fail2Ban-Setup) to work properly.
