Function of addping in updown monitor is unclear
Hi,
the function of the addping (secondary IP) in updown monitor is unclear to me. Is it a secondary set of IP to be used to vote for overall outage? Or is it just used for logging online/offline for those IP? Maybe it could be made more clear in the readme section.

Secondary IP addresses are useful as documented here.
Here's an example: If your primary ping address is 1.1.1.1, you may want to determine if, when the network goes inaccessible, whether the issue is that your external internet is offline, or your router (itself) is offline. In this case, you'd add your router IP (e.g., 192.168.1.1, or whatever it is), as a secondary IP.
If both the primary and the secondary are down, then the problem is your router.
If only the primary (e.g., 1.1.1.1) is down, then your internet connection is down.
This is also very handy if you have a scenario with two routers (e.g. internet--ISP router--LAN router). In this case you'd have the internet as the primary ping address, and each of your routers as a secondary address. This helps determine which router to investigate should things go pear-shaped.
Does this help?

Yes, indeed. I will alter my setup as per your recommendations.
Great. And I'll add some altered version of the above explanation to the README. Thanks for pointing out the doc deficiency.
