I would like to understand how connectivity is monitored in 'Security & SD-WAN > Monitor > Appliance Status'
Is the MX probed from the outside > in (ie from a Meraki datacentre to the MX)?
Or is the MX probing from the inside > out (ie from itself to a Meraki datacentre) then reporting its connectivity?
This is our MX64 connectivity graph for a typical day at a serviced office in China. If the monitoring is outside > in, then I wonder how accurate this graph could be as we know this device is behind one or more firewall/router/nat devices (and in China!)

An easy way to test would be to setup separate monitoring running from a device inside our network, but before I do that I would like to know the answer to my question.
Thanks in advance.
