MS SQL 2008 Compilations/Second Spiking

Is there a way to find out what queries or other might be causing a spike in Compilations per Second performance metric for MS SQL Server? You can see in the screen grab of my monitoring that spike started at 5am pacific time. Normally this hovers around 20/sec but since the weekend it's been trending up and even more pronounced today. I can't get anyone in our team to fess up. I need a way see what activity might be triggering this? Any tips from SQL experts?Graph

Youl'll need to capture the queries to see what's going on. For that you can use SQL Profile or Extended Events.
Also check for any jobs that might be running.

I didn't see anything of interest in the event logging. Can you expand on what you mean by using SQL Profile?
Vitor MontalvãoMSSQL Senior EngineerCommented:
SQL Server Profiler is a monitoring tool from Microsoft that helps you capture information about queries, locks, connections, etc. Basically everything that is happening at the present in the SQL Server instance. You can found more information here.

Extended Events is the replacer for SQL Server Profiler (use less resources with better performance) and you can find information about it here.
