convert Convert API trace to JSON or Python and back
replay Replay messages to running VPP instance
To convert an API trace file to JSON:
vppapitrace convert /tmp/api.trace trace.json
To convert an (edited) JSON file back to API trace for replay:
vppapitrace convert trace.json api-edited.trace
To generate a Python file that can be replayed:
vppapitrace convert /tmp/api.trace trace.py
vppapitrace convert trace.json trace.py
Replay it to a running VPP instance:
vppapitrace replay --socket /tmp/api.trace
In VPP that file can be replayed with:
vpp# api trace replay api-edited.trace
This patch also modifies the API binary trace format, to include the
message id to message name table.
