One or multiple data sources for multiple influx db databases?

#1

I’m running one influxdb server but have multiple databases.

Is it best practice to setup multiple data sources in Grafana (i.e. one data source for each influxdb database) or only one data source?

When adding a data source to Grafana, it shows the following:

Database Access

Setting the database for this datasource does not deny access to other databases. The InfluxDB query syntax allows switching the database in the query. For example: SHOW MEASUREMENTS ON _internal or SELECT * FROM “_internal”…“database” LIMIT 10

…but when I try to use the Explore in Grafana to see my other databases I can’t seem to figure it out?
