Log latency data in Thread

[Rorisang]

Hi. I have set up a nine node mesh using Thread and the nRF52840 chips. I am using the COAP example. All my nodes are visible and i am able to send pings between them. I am stuck as to how i can record/log the ping latency between any two nodes. I want the data set consisting of IP addresses of the nodes pinging and the latency for each ping. For example, i will use the syntax:

ping XXXXXXXX 8 100 1, where XX... is the address of the node i am pinging, 8 is the byte size of the ping, 100 is the packet count and 1 is the time between sending each ping.

Please, help. Thank you.

I'm not quite following what it is that you want to do. Where is this log going to end up? at the MQTT broker,  one of the nodes, all of the nodes?
