Create a Nagios check to ensure that Onionoo is updating correctly
Can we have a Nagios check that fetches https://onionoo.torproject.org/summary?limit=0, say, once per hour, and makes sure that the two contained timestamps are not older than, say, three hours?
And can Nagios send me mail when that warning is triggered?
I can maybe help write that check if I know what language to use and what output to provide.
