NAME

Net::Prometheus::Counter - a monotonically-increasing counter metric

SYNOPSIS

use Net::Prometheus;

my $client = Net::Prometheus->new;

my $counter = $client->new_counter(
   name => "requests",
   help => "Number of received requests",
);

sub handle_request
{
   $counter->inc;
   ...
}

DESCRIPTION

This class provides a counter metric - a value that monotonically increases, usually used to represent occurrances of some event that happens within the instrumented program. It is a subclass of Net::Prometheus::Metric.

CONSTRUCTOR

Instances of this class are not usually constructed directly, but instead via the Net::Prometheus object that will serve it:

$counter = $prometheus->new_counter( %args )

This takes the same constructor arguments as documented in Net::Prometheus::Metric.

METHODS

inc

$counter->inc( [ @label_values ], $delta )

$child->inc( $delta )

Increment the current value for the gauge. $delta will default to 1 if not supplied and must be non-negative.
