I do not understand the downtime channel of the ping sensor. My router is on the same switch as my server hosting PRGT. The average ping time is 2ms but I show a downtime average of about 10.5ms. My graph for this is full of red lines which seem to sit on top of the green, indicating no non-responses from ping.
I have another site which I connect via VPN and am also monitoring. That router shows a downtime average of 2.7ms with an average response time of 13ms.
If I am having communications issues with my local router, then my remote should be worse. What is the downtime showing me?
