Json plugin not seen on server side after being plugged in

since I’m not a paying member, I don’t have access to people who can fix things.
perhaps the community can help.

first, the jsonSimple plugin is shown as:

“simpod-json-datasource version: 0.1.4”, I’m thinking the “l” and “e” keys are close to “o” and d.

second, on maxosx, I installed simple jason using the cli tool, then stopped and restarted the server
but simple json (or any variant of its spelling) still wasn’t seen as a data source via the served URL.
(I am following the Grafana “getting started” tutorial.)
I’m thinking where the plugin was installed and where the pluging is searched for are two different places.

Any help?
