By default, the correlator outputs diagnostic information every five seconds, and sends it to the correlator log file at INFO log level. You can use this information to diagnose common problems. See Descriptions of correlator status log fields for further information.

The correlator sends this information to its log file during normal operation. While it is possible to disable this output (by setting the correlator's log level to WARN), doing so is not advisable. In the unlikely event that you run into a problem, Apama Technical Support always ask for a copy of this log file, as the information in it is often useful for diagnosing the nature of a failure.
