 ## Hooks
 
 The plugin uses the following hooks:
 
--   `onRoute`: to generate the route labels at startup time if `routes.mode` is set to `'static'`.
--   `onClose`: to close the [Dats](https://github.com/immobiliare/dats) instance and the [sampler](https://github.com/dnlup/doc#new-docsampleroptions) instance.
--   `onRequest`: it registers a hook to count requests and, if `routes.mode` is set to `'dynamic'`, it adds another one to generate the route label.
--   `onResponse`: to measure response time
--   `onError`: to count errors

 ## Request and Reply routeConfig
 
 The plugin adds a `metrics` object to the `Request.routeOptions` and `Reply.request.routeOptions` for convenience with the following properties:
 
--   `routeId` <`string`> The id for the current route
--   `fastifyPrefix` <`string`> The prefix of the fastify instance registering the route, with the `/` replaced with `.` and without the `.` at the beginning.
--   `routesPrefix` <`string`> The routes prefix passed to the plugin options and without `.` at the beginning and end.

 There are two different modes to generate the label for each route:
 
--   `static`
--   `dynamic`
+- `static`
+- `dynamic`

--   the routes prefix passed to the plugin option `routes.prefix`, we call it `routesPrefix`
