Prometheus AlertManager is the component that manages sending, inhibition and silencing of the alerts generated from Prometheus. The AlertManager can be configured to send alerts to variety of receivers. Refer [Prometheus AlertManager receivers](https://prometheus.io/docs/alerting/latest/configuration/#receiver) for more details.

Follow below steps to enable and use AlertManager.

## Deploy and start AlertManager

<h3 id="Receive_operator">Receive operator</h3>

<p>
For an operand <code>ch</code> of <a href="#Channel_types">channel type</a>,
the value of the receive operation <code>&lt;-ch</code> is the value received
from the channel <code>ch</code>. The channel direction must permit receive operations,
and the type of the receive operation is the element type of the channel.

Let's imagine that you have a database `fake_db` that only receives JSON compatible data.

For example, it doesn't receive `datetime` objects, as those are not compatible with JSON.

So, a `datetime` object would have to be converted to a `str` containing the data in <a href="https://en.wikipedia.org/wiki/ISO_8601" class="external-link" target="_blank">ISO format</a>.

	maxSubscribers int32

	// not atomics:
	subs []*Sub[T]
	sync.RWMutex
}

// Publish message to the subscribers.
// Note that publish is always non-blocking send so that we don't block on slow receivers.
// Hence receivers should use buffered channel so as not to miss the published events.
func (ps *PubSub[T, M]) Publish(item T) {
	ps.RLock()
	defer ps.RUnlock()
	for _, sub := range ps.subs {

We are still using the same `OAuth2PasswordRequestForm`. It includes a property `scopes` with a `list` of `str`, with each scope it received in the request.

And we return the scopes as part of the JWT token.

/// danger

For simplicity, here we are just adding the scopes received directly to the token.

    val connection = connect(peer)
    connection.writePingAndAwaitPong() // Ensure the SETTINGS have been received.
    val stream = connection.newStream(headerEntries("a", "android"), true)
    val sink = stream.getSink().buffer()
    sink.writeUtf8("abcdefghi")
    sink.flush()

    // Verify the peer received what was expected.
    peer.takeFrame() // PING
    val headers = peer.takeFrame()
