Logging in YDB
Each YDB component writes messages to logs at different levels. They can be used to detect severe issues or identify the root causes.
Logging setup
You can configure logging for the various components of the YDB in the Embedded UI.
There are currently two options for running YDB logging: manually or using systemd.
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.
Using systemd
Default logs are written to journald
and can be retrieved via journalctl -u ydbd
.
