The dbo.CollectionExceptionsServer table allows you to turn off a single collection (module) for a particular instance.

For example, to turn off error log searches for an entire server, insert a row into dbo.CollectionExceptionsServer for that particular instance, using the collection table name (“Collector.ErrorLog”) as the CollectionName: 
INSERT INTO dbo.CollectionExceptionsServer ( InstanceID, CollectionName )
VALUES  ( 11 , 'Collector.ErrorLog' );

Let's take another example: If Svr1 is a Gold level server, but you don’t want any job scripts generated for it, insert a row to dbo.CollectionExceptionsServer (using the InstanceID for Svr1 from dbo.Servers: 
​INSERT INTO dbo.CollectionExceptionsServer ( InstanceID, CollectionName )
VALUES  ( 99 , 'JobScript'  );
 
Now, InstanceID 99 (Svr1) will no longer take part in the Script Jobs collection!
