Sure. I posted something similar this morning so will link it here:
I have posted the variables, in the past, using Particle.publish() so I could see events evolve in the Events console, for example. Now, I just use the two above statements in a small routine called every 3 minutes from loop(). If abnormal conditions persist, as in the above post link, for 3 minutes I typically call System.reset(). At present, my devices reset every 2 or 3 days on average.
Interesting note you made about the device.cloud.coap.transmit value. I will take a closer look at that, too. I might write a set of "conditions" to EEPROM so I can see what triggered a device last restart.
