I want to keep an eye on my Internet service provider after a series of prolonged outages, to that end I setup a Grafana dashboard to monitor my connectivity to various online services.

Grafana supports SQL through MySQL/MariaDB, PostgreSQL & SQL Server. Additionally Grafana supports the PostgreSQL extension TimescaleDB, this database is the best fit of all the SQL databases for Grafana since it is built specifically for large-scale time-series datasets.
