I've started creating a separate deadlock extended event myself.
Here's an example of how to create a deadlock ext event. Naturally your WITH options may vary. You can then use SSMS / Management / Extended Event / Deadlocks to look at any deadlocks that do occur.
CREATE EVENT SESSION [Deadlocks] ON SERVER ADD EVENT sqlserver.xml_deadlock_report
ADD TARGET package0.event_file(SET filename=N'<path_and_file_of_your_extended_events_deadlock_file>',max_file_size=(50),max_rollover_files=(8))
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=ON,STARTUP_STATE=ON)
SQL DBA,SQL Server MVP(07, 08, 09) Prosecutor James Blackburn, in closing argument in the Fatal Vision murders trial: "If in the future, you should cry a tear, cry one for them [the murder victims]. If in the future, you should say a prayer, say one for them. And if in the future, you should light a candle, light one for them."
