Testing a Specific Transaction

If a specific video is having delivery problems, you can use the trace log facility to debug. This
involves setting the delivery trace:
delivery protocol http trace enable
And using WGET (or other tool, cURL, and so forth) to request the problem video with this
header added:
X-NKN-Trace
The Media Flow Controller HTTP modules then set the flag "HRF_TRACE_REQUEST" as well
as other flags that direct each relevant module to log meaningful trace points. To see the trace
points and for additional information, see

Enabling Debug Operations

Media Flow Controller provides a system-level debugging utility as well as a trace facility; see
"Trace Log (tracelog)" on page 223
Important!
commands should be turned on only for troubleshooting specific problems or during
troubleshooting sessions with technical support personnel. Excessive debugging output can
render the system inoperable.
1. Generate debugging information for all system functions.
debug generate dump
