METRICS_ANY_ADAPTERSinceversion0.04.
Sets the default adapter type to use if the program has not otherwise requested one.
Normally this is set to "Null", which loads Metrics::Any::Adapter::Null. By overriding this to a
different value, a default adapter can be loaded without modifying the program. This may be useful for
example, when running unit tests:
$ METRICS_ANY_ADAPTER=Stderr ./Build test
Additional arguments can be specified after a colon, separated by commas or equals signs.
$ METRICS_ANY_ADAPTER=File:path=metrics.log ./program.pl
Note that if a program requests a specific adapter that will override this variable.
A limited attempt is made at supporting nested arguments wrapped in square brackets, to allow basic
operation of the Metrics::Any::Adapter::Tee adapter via this variable to itself pass arguments into child
adapters:
$ METRICS_ANY_ADAPTER=Tee:Prometheus,[File:path=metrics.log] perl ...
This should be considered a best-effort scenario useful for short-term testing and debugging. For more
complex requirements in your script or program, it is better to use the import arguments directly as then
any perl data structures can be passed around.
