NAME

       "Metrics::Any::Adapter::File" - write metrics to a file

SYNOPSIS

          use Metrics::Any::Adapter 'File', path => "metrics.log";

DESCRIPTION

       This Metrics::Any adapter type writes observations of metric values into a file. This may
       be helpful while debugging or otherwise testing code that reports metrics.

       For example, by setting the "METRICS_ANY_ADAPTER" environment variable to configure the
       adapter, a metric log will be written as a side-effect of running a unit test:

          $ METRICS_ANY_ADAPTER=File:path=metrics.log perl -Mblib t/01test.t

       The generated file can then be inspected to see what metric values were reported while the
       program was running.

       In particular, specifying the file /dev/null allows the full metrics generation path to be
       tested with the code under test seeing a "real" adapter even though the output goes
       nowhere.

          $ METRICS_ANY_ADAPTER=File:path=/dev/null ./Build test

       Distribution and timing metrics are tracked with a running total and count of
       observations.

       This adapter type does not support batch mode reporting.

ARGUMENTS

       The following additional arguments are recognised

   path
       The path to the file to write to.
