# Grafana Dashboards

This folder contains Istio's official Grafana dashboards.
These get publish to [Grafana](https://grafana.com/orgs/istio/dashboards) during release, and are bundled into our
[Grafana sample](../../../samples/addons/grafana.yaml).

## Jsonnet

Newer dashboards are generated with [Jsonnet](https://jsonnet.org/) with the [Grafonnet](https://grafana.github.io/grafonnet/index.html).

!!! info
    The `OAuth2PasswordRequestForm` is not a special class for **FastAPI** as is `OAuth2PasswordBearer`.
