Comment:

 this is indeed a complex panel to create! i managed to make one using
 "singlestat" - I couldn't figure how to make the "alert list" thing work -
 but it's kind of clunky:

 https://grafana2.torproject.org/d/fC77Nk6Wz/blackbox-probe-state

 now after asking on #prometheus (freenode), i was told there's a Granafa
 plugin specifically for that purpose. it's really heavy on the Javascript,
 but it seems to actually work and provide a much better visualization.
 here's the dashboard I created with the plugin:

 https://grafana2.torproject.org/d/6shXNz6Wz/blackbox-target-availability

 the plugin is:

 https://grafana.com/grafana/plugins/flant-statusmap-panel/installation

 i installed it with:

 {{{
 sudo -u grafana grafana-cli plugins install flant-statusmap-panel
 service grafana-server stop
 service grafana-server start
 }}}

 ... which needs to be added into Puppet if we're happy with the results.

 let me know how that looks for you.

 (and yes, it does seem like all blackbox targets except bridges.tpo are
 down.)
