Data retention

Watchdog deletes old data on its own, every six hours, starting a minute after the server boots. Set a value of 0 to keep that kind of data forever.

Variable	Default	Removes
RETENTION_EVENT_DAYS	90	Error events, and issues not seen within the period
RETENTION_PERFORMANCE_DAYS	30	Transactions and metrics
RETENTION_REPLAY_DAYS	30	Session replays

Deletion is permanent. Lower values keep your database small, which matters most for replays.
