Connectivity between LogicMonitor collector to LogicMonitor SaaS Platform

I don't really know the communications between the Collector and the platform, but I think of the Collector just frequently checking into the platform asking for any changes, scheduling, uploading new data, or to run new commands. But I don't really know myself if it's via reverse tunneling or just frequent polling. It kinda just works. I guess you might be able to sniff the traffic. It is encrypted and the key is in a config file, but the key rotates daily.
