Extended Events

✓ functional

List Extended Events sessions with running state and per-session detail; start and stop are script-first.

Two grids side by side: the left lists the sessions with their startup state and whether each is currently running; select one and Show Events & Targets fills the right grid with that session's events and targets. Starting and stopping a session is script-first: Script Start and Script Stop open the exact ALTER EVENT SESSION … STATE = START|STOP statement in a tab for review rather than firing from the dialog - the footer says as much.

Scope-aware. Opened from a database, it lists that database's own database_event_sessions. Opened from the server, it lists the instance's server-scoped sessions - and on Azure SQL Database, which only has database-scoped sessions, it falls back automatically.
