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.
You can configure logging for the various components of the YDB monitoring system.
There are currently two options for running YDB logging.
YDB provides standard mechanisms for collecting logs and metrics.
Logging is done to standard
stderr streams and can be redirected using popular solutions. We recommend using a combination of Fluentd and Elastic Stack.
Default logs are written to
journald and can be retrieved via
journalctl -u ydbd
