"Net::Prometheus::Registry" \- a collection of metrics collectors
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This class, or instances of it, acts as a simple storage array for instances
derived from Net::Prometheus::Metric, known as \*(L"collectors\*(R".
.PP
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.
.SH "CONSTRUCTOR"

.Vb 2
\&   $collector = Net::Prometheus::Registry\->register( $collector )
\&   $collector = $registry\->register( $collector )
.Ve
.PP
Adds a new collector to the registry. The collector instance itself is
returned, for convenience of chaining method calls on it.
.SS "unregister"
