## Publish MinIO events via AMQP

Install RabbitMQ from [here](https://www.rabbitmq.com/).

### Step 1: Add AMQP endpoint to MinIO

The AMQP configuration is located under the sub-system `notify_amqp` top-level key. Create a configuration key-value pair here for your AMQP instance. The key is a name for your AMQP endpoint, and the value is a collection of key-value parameters described in the table below.

```
KEY:

type HealthOptions struct {
	Maintenance    bool
	DeploymentType string
	NoLogging      bool
}

// HealthResult returns the current state of the system, also
// additionally with any specific heuristic information which
// was queried
type HealthResult struct {
	Healthy       bool
	HealthyRead   bool
	HealingDrives int
	ESHealth      []struct {

	FSTPQ	(F3, F4), 11(RSP)    // fb2f0091631300ad
	FSTPQ	(F3, F4), 1024(RSP)  // fb031091631300ad
	FSTPQ	(F3, F4), 4104(RSP)
	FSTPQ	(F3, F4), x(SB)
	FSTPQ	(F3, F4), x+8(SB)

// System Register
	MSR	$1, SPSel                          // bf4100d5
	MSR	$9, DAIFSet                        // df4903d5
	MSR	$6, DAIFClr                        // ff4603d5
