Request from a user:

It occurred to me that the new sFlow-APPLICATION export might be another way for an OWAMP probe to contribute measurements into the "bigger picture", so that end-to-end delay/loss statistics could be correlated with measured traffic-counters and traffic-flows at all points along the tested path.

If an OWAMP probe were able to submit transaction-samples that included at least these fields...

clientIP
serverIP
delay
jitter

...then it would map easily into the sFlow-APPLICATION message structure.

The easiest way to do it would be to send a JSON structure in a UDP packet localhost:36343, where hsflowd is listening. hsflowd will then turn that into a valid binary sFlow feed. Here is an article on the mechanism:
