Opal + InfluxDB
Opal supports out-of-the-box integrations with self-hosted databases like InfluxDB. You can define access at multiple levels, all the way down to table and column-level access. With Opal's just-in-time short-lived access, the right people will see the right information at the right time. You can access your database via your favorite database viewers like Postico or the command line, and even manage policies on the fly for temporary users via Opal's built-in policy editor.
