The addSource Stored Procedure This procedure is used by the log collector service to add a new log source that was detected in the file system. Notice that we’re setting the transaction isolation level to Serializable for the duration of this procedure. This way, we can make sure that two instances of the log collector service, running on different computers, cannot add the same log source twice.
