About the OpenFlow Trace log

The number of events that can be held in the trace log is limited by system memory. For this
reason, Hewlett Packard Enterprise recommends that you export to a remote storage location
any trace log content you want to retain, and to clear the controller trace log whenever its content
is not needed on the controller itself.
