capture sql server query execution using extended events

extended events (xevents) is a powerful feature in sql server that allows you to collect and analyze performance data. it provides a lightweight way to capture events occurring within the sql server instance and is often used for troubleshooting and performance tuning.

tutorial: capturing sql server query execution using extended events

step 1: understanding extended events

extended events are designed to help you monitor and troubleshoot sql server. they can capture a variety of events, including query execution, blocking, deadlocks, and much more. the events collected can be filtered and stored in a session for analysis.

step 2: creating an extended events session

to capture sql server query execution events, you can create an extended events session. below is a step-by-step guide along with sql code examples.

step 2.1: create the session

you can create an extended events session using the following sql syntax:

```sql
create event session [queryexecutioncapture] on server
with (max_memory=4096 kb, event_retention_mode=allow_single_event_loss, max_dispatch_latency=30 seconds, max_event_size=0 kb, memory_partition_mode=none, track_causality=off, startup_state=off);
go
```

- **event**: this captures the `sql_statement_completed` event, which occurs whenever a sql statement completes execution.
- **actions**: this specifies additional data to capture, such as the sql text, database name, and client application name.
- **filters**: the `where` clause filters the events to capture only those related to a specific d ...
