Can we remove GetTor statistics from metrics-*?
The graph on packages requested from GetTor was broken for six weeks between early June and mid-July, and hardly anybody noticed. The problem (#6275 (moved)) is fixed as of today (thanks kaner!), but this bug makes me think whether we need these statistics at all.
Graphing requested GetTor packages involves quite a bit of code in different places, including: GetTor, metrics-db, metrics-lib, and metrics-web. Each code place periodically needs maintenance: there are bugs such as #6275 (moved), new code like metrics-lib or stem need parsing support if they want to support all metrics data, etc. We added these statistics a few years back upon sponsor request, but that sponsor isn't paying for maintenance anymore (or ever since). GetTor data is of little value for learning interesting stuff about the Tor network as a whole, and we wouldn't add statistics for similar services to metrics for maintenance reasons. Just because we have GetTor statistics is a rather bad reason for keeping them.
I suggest archiving the GetTor stats file and graphs we have and removing all stats generating and processing code from the various code bases.
