### 5. Start Prometheus

Start (or) Restart Prometheus service by running

```sh
./prometheus --config.file=prometheus.yml
```

Here `prometheus.yml` is the name of configuration file. You can now see MinIO metrics in Prometheus dashboard. By default Prometheus dashboard is accessible at `http://localhost:9090`.

          // we are on the stack, now wait for completion.
          while (true) {
            LockSupport.park(this);

```Python
user_in = UserIn(username="john", password="secret", email="******@****.***")
```

and then we call:

```Python
user_dict = user_in.dict()
```

we now have a `dict` with the data in the variable `user_dict` (it's a `dict` instead of a Pydantic model object).

And if we call:

```Python
print(user_dict)
```

we would get a Python `dict` with:

```Python

import (
	"bytes"
	"encoding/gob"
	"io"
	"testing"
	"time"

	"github.com/tinylib/msgp/msgp"
)

func BenchmarkDecodeVolInfoMsgp(b *testing.B) {
	v := VolInfo{
		Name:    "uuid",
		Created: time.Now(),
	}
	var buf bytes.Buffer
	msgp.Encode(&buf, &v)
	rd := msgp.NewEndlessReader(buf.Bytes(), b)
	dc := msgp.NewReader(rd)
	b.Log("Size:", buf.Len(), "bytes")
	b.SetBytes(1)
	b.ReportAllocs()

	for b.Loop() {
