perl v5.40.0                                       2024-11-09                      Net::Prometheus::Summary(3pm)

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

          $summary = $prometheus->new_summary( %args )

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

   observe
          $summary->observe( @label_values, $value )
          $summary->observe( \%labels, $value )

          $child->observe( $value )

       Increment the summary sum by the given value, and the count by 1.

       This class provides a summary metric - a combination of a running total and a counter, that can be used
       to report on total and average values of observations, usually times. It is a subclass of
       Net::Prometheus::Metric.

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

             name => "request_seconds",
             help => "Summary request processing time",
          );

          sub handle_request
          {
             my $start = time();

             ...

             $summary->observe( time() - $start );
          }
