I’m looking for help with understanding meaning of metrics.
In NR Synthetics, simple ping check, the timing is broken down to:
While DNS lookup, SSL negotiation, and Connecting meaning seem clear to me, it’s not so much for other phases. For example, does “Sending” mean sending the request from NR machine to my server, or does it mean my server sending the response? What is “Receiving”? I can see it takes only microseconds, so what is it? It’s using HEAD method, so not fetching body, but still microseconds sound not very realistic to me.
Any help / hint is much appreciated, thanks
