OpenFlow Trace log
This troubleshooting tool logs OpenFlow conversations captured in messages to and from the
controller and the OpenFlow devices it manages.
You can export the captured messages in the trace log to a CSV (Comma-Separated Values)
file that can be opened by applications such as Excel that are designed to accommodate this file
type. This enables you to create a filter to display only the messages from the specific data paths
you want to examine.
