# Net::Prometheus::Registry(3pm)

a collection of metrics collectors

## NAME

"Net::Prometheus::Registry" - a collection of metrics collectors

## DESCRIPTION

This class, or instances of it, acts as a simple storage array for instances derived from Net::Prometheus::Metric, known as "collectors".

A single global collection is stored by the module, accessible via the class methods. Additional collections may be made with the constructor and then accessed by instance methods.

## CONSTRUCTOR

### new

```
   $registry = Net::Prometheus::Registry->new;
```

Returns a new registry instance.

## METHODS

### register

```
   $collector = Net::Prometheus::Registry->register( $collector );
   $collector = $registry->register( $collector );
```

Adds a new collector to the registry. The collector instance itself is returned, for convenience of chaining method calls on it.

### unregister

```
   Net::Prometheus::Registry->unregister( $collector );
   $registry->unregister( $collector );
```

Removes a previously-registered collector.

### collectors

```
   @collectors = Net::Prometheus::Registry->collectors;
   @collectors = $registry->collectors;
```

Returns a list of the currently-registered collectors.
