 There are a few things that we can check, some are easier than others.

 * Is the host up and the webserver running? (this is easy with built-in
 checks)
 * Is the tgen server running on the Internet? (this is easy with built-in
 checks)
 * Is the analyze task running? (needs a plugin)
 * Is the tgen server running on an Onion service? (needs a plugin)

 For monitoring the Onion service, I'm looking at reusable plugins, so
 there are two tests. One checks to see how old the descriptor is and a
 second test actually tries connecting to the service. The first of these
 tests is affected by #28269 (but not blocked) and both are blocked by
 [[https://github.com/robgjansen/onionperf/issues/42|onionperf#42]].

 As a workaround for monitoring the Onion service, which really is the bit
 that is breaking, we can instead monitor the analysis of timeouts from Tor
 Metrics' CSV files.
