# Logs

Each YDB component writes messages to logs at different levels. They can be used to detect severe issues or identify the root causes of issues.

## Logging setup

You can configure logging for the various components of the YDB monitoring system.

There are currently two options for running YDB logging.

### Manually

YDB provides standard mechanisms for collecting logs and metrics.
Logging is done to standard stdout and stderr streams and can be redirected using popular solutions. We recommend using a combination of Fluentd and Elastic Stack.

### Using systemd

Default logs are written to journald and can be retrieved via

journalctl -u ydbd
