Is this being worked on somewhere already?
Grafana Labs says they'll be releasing a postgres connector within the next couple months, which would work with Timescale (they released MySQL earlier this month). We'll follow up.
Thanks for interest!
I've written a postgresql datasource for grafana and have opened a pullrequest see https://github.com/grafana/grafana/pull/9209
The pull request for the postgres datasource got merged so the next release of grafana will have postgres support.
Grafana v4.6 is live! Thanks to @svenklemm for writing the PostgreSQL datasource included in the release: http://docs.grafana.org/guides/whats-new-in-v4-6/
