3.13 OpenFlow trace display

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.

3.13.1 About the trace log

The number of events that can be held in the trace log is limited by system memory. For this reason, HP 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.
