## Using Micrometer

Access the `/micrometer` endpoint which reports the newly-added timer and counter.

```bash

`SimpleGreetService` has a micrometer counter that is incremented each time a GET request is made at
227-
`http://localhost:8080/greet-count`. The counter name is `allRequests` and is shown in the console
228-
with the number of time it was triggered.
229-
230-
```
231-
curl http://localhost:8080/micrometer
