This sample configuration uses a `webhook` at http://127.0.0.1:8010/webhook to post the alerts.
Start the AlertManager and it listens on port `9093` by default. Make sure your webhook is up and listening for the alerts.

## Configure Prometheus to use AlertManager

Add below section to your `prometheus.yml`
```yaml
alerting:
  alertmanagers:
  - static_configs:

	cfg.Proxy = proxy

	if transport == nil {
		// when transport is nil, it means we are just validating the
		// inputs not performing any network calls.
		return cfg, nil
	}

	// Make sure to clone the transport before editing the ProxyURL
	if proxyURL != nil {
		if tr, ok := transport.(*http.Transport); ok {
			ctransport := tr.Clone()
			ctransport.Proxy = http.ProxyURL((*url.URL)(proxyURL))

		fmt.Fprintln(c.output, string(logJSON))
		return nil
	}

	if entry.Level == logger.EventKind {
		fmt.Fprintln(c.output, entry.Message)
		return nil
	}

	traceLength := len(entry.Trace.Source)
	trace := make([]string, traceLength)

	// Add a sequence number and formatting for each stack trace
	// No formatting is required for the first entry
	for i, element := range entry.Trace.Source {

	if !simdjson.SupportedCPU() {
		t.Skip("Unsupported cpu")
	}

	for _, tt := range testCases {
		t.Run(tt.name, func(t *testing.T) {
			ref := loadCompressed(t, tt.name)

			var err error
			dst := make(chan simdjson.Object, 100)
			dec := NewElementReader(dst, &err, &json.ReaderArgs{ContentType: "json"})
			pj, err := simdjson.ParseND(ref, nil)
			if err != nil {
				t.Fatal(err)
			}
			i := pj.Iter()

Do not remove `null` checks on public API boundaries, even if the annotations (or rather lack of them) suggest this.
Not all client code is compiled with NullAway.
Do not make a parameter `@Nullable` just to check and throw a `NullPointerException` when it is `null`. 

## Status

ACCEPTED

## Consequences

* Classes are forced to have consistent nullability annotations.

 * remain in their original namespace. This reduces the final Gradle distribution
 * size and makes us more conscious of which parts of a library we really need.
 *
 * WARNING: if you decide to do the minification by hand, make sure that you cover all paths of loading classes:
 * reflection, dynamic loading, etc. and understand how the library works internally.
