Differences in Latency between EdgeDX and VDA Protocol

A user asked about the differences in latency between EdgeDX and the ControlUp VDA protocol. It was suggested that this may be due to different sample rates and frequencies. The user expected the maximum latency in HDX to match that of EdgeDX, but it was discussed that this may not be the case if HDX is not sampling at the same time. ControlUp URLs for EdgeDX and the VDA were also shared.

Question regarding differences in latency seen in EdgeDX vs the VDA protocol latency. A report for a user shows very good protocol latency and peak latency on the VM, while EdgeDX network latency has a number of very high spikes. Is this simply the difference between sample rate, or overall smoothing of the protocol latency as the EdgeDX latency numbers appear to be instantaneous occurrences rather than prolonged high latency. Shouldn’t the peak latency on the VDA match what is seen at the device though?

Controlup VDA

EdgeDX does an ICMP ping to the target every minute.

Protocol latency is the latency as reported by the remoting protocol, HDX I assume in your case.

ICMP could be getting deprioritized over the HDX protocol?

I figured it has to be something with regards to sample time and frequency. I guess I had expected the max latency in HDX to match what the max latency is in EdgeDX, but I guess there is a chance if HDX doesn’t sample at the same time as EdgeDX, they would not match.
