Comment (by irl):

 I would like for these systems to be as open/transparent as is possible.
 The demarcation between a system that collects metrics and Tor Metrics
 should not just be for Tor Metrics. Anyone should be able to do what Tor
 Metrics does. This means that services publish data, and we pull from the
 service.

 It does not need to be a web server. If there is not already a webserver
 then a Gopher server or TCP port that dumps out the document are also fine
 as far as I'm concerned, maybe karsten has other opinions.

 Increasingly I'm thinking that the Tor directory protocol meta format is a
 good format to have metrics in. We already have parsers for these that are
 fast and efficient, and it's easier to detect errors due to the strict
 format (even if #30105 and similar things sometimes slip through). The
 document format also provides for signing of documents, which I'd like to
 see more of our data sources doing. #29624 is looking at defining a new
 format for exit lists, and is using the meta format with Ed25519
 signature.
