Metrics::Any::Adapter:UsereContributed Perl DoMetrics::Any::Adapter::File(3pm)
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.
