Source: https://featherpanel.com/docs/api/reference/admin/kpi/system/

Defined in [`backend/app/routes/admin/kpi/system.php`](https://github.com/MythicalLTD/FeatherPanel/blob/15b94e9fc9df233123706b47c42728b81e48cb3d/backend/app/routes/admin/kpi/system.php). Authentication used here: **Admin**. Read [Authentication](https://featherpanel.com/docs/api/authentication/) for how to send credentials and [Rate limits and errors](https://featherpanel.com/docs/api/rate-limits-and-errors/) for the response envelope.

Paths, methods, permissions and rate limits come from the route file. Summaries, parameters and response codes come from the OpenAPI annotations on the controllers; endpoints without annotations show only what the route file declares.
