title: xevent trace doesn't return anything in SQL Server 2019
body: <p>I'm trying to watch trace events on SQL Server 2019 and created an Extended Events session like this:</p>
  <pre><code>CREATE EVENT SESSION [test] ON SERVER 
  ADD EVENT sqlsni.trace
  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
  </code></pre>
  <p>However, the started session doesn't return anything when watching Live Data.
  On an SQL Server 2017 the exact same thing returns data as expected.</p>
  <p>On both SQL servers I'm using the SA account</p>
  <p>I also tried adding a file target. But the file target also remains empty...</p>
  <p>Is there anything in SQL Server that needs to get enabled? Any other reason for this not to work?</p>
