- MinIO exports Prometheus compatible data by default which is resource centric as an authorized endpoint at `/minio/v2/metrics/resource`.

All of these can be accessed via Prometheus dashboard. A sample list of exposed metrics along with their definition is available on our public demo server at

```sh
curl https://play.min.io/minio/v2/metrics/cluster
```

func init() {
	// Inject metrics.
	ioutilx.OsOpenFile = OpenFile
	ioutilx.OpenFileDirectIO = OpenFileDirectIO
	ioutilx.OsOpen = Open
}

type osMetrics struct {
	// All fields must be accessed atomically and aligned.
	operations [osMetricLast]uint64
	latency    [osMetricLast]lockedLastMinuteLatency
}

// time an os action.
func (o *osMetrics) time(s osMetric) func() {
	startTime := time.Now()

  }

  public static <E> Builder<E> builderWithExpectedSize(int size) {
    return new Builder<E>(size);
  }

  public static class Builder<E> extends ImmutableCollection.Builder<E> {
    // accessed directly by ImmutableSortedSet
    final ArrayList<E> contents;

    public Builder() {
      this.contents = Lists.newArrayList();
    }

    Builder(int initialCapacity) {

        trans2QueryPathInfo = new Trans2QueryPathInformation(mockConfig, TEST_FILENAME, TEST_INFO_LEVEL);

        assertNotNull(trans2QueryPathInfo);

        // Configuration is accessed during initialization
        // Verify at least that getPid() and getTransactionBufferSize() were called
    }

```JSON
{
    "message": "Hello World",
    "root_path": "/api/v1"
}
```

So, it won't expect to be accessed at `http://127.0.0.1:8000/api/v1/app`.

Uvicorn will expect the proxy to access Uvicorn at `http://127.0.0.1:8000/app`, and then it would be the proxy's responsibility to add the extra `/api/v1` prefix on top.
