6 "Metrics::Any::Adapter" - set the "Metrics::Any" adapter for the
7 program
8
10 In a program or top-level program-like module:
11
12 use Metrics::Any::Adapter 'Prometheus';
13
15 The "use" statement which loads this module sets the adapter module for
16 Metrics::Any to report metrics generated by an modules the program
17 uses.
18
19 The first value passed should be a string giving the name of an adapter
20 module, which will be expected under the
21 "Metrics::Any::Adapter::"-prefix. This module will be loaded and set
22 as the adapter to use. Any additional arguments will be passed to the
23 constructor of the adapter instance.
24
25 use Metrics::Any::Adapter Custom => "another arg";
26
27 # implies
28 $adapter = Metrics::Any::Adapter::Custom->new( "another arg" );
29
31 METRICS_ANY_ADAPTER
32 Since version 0.04.
33
34 Sets the default adapter type to use if the program has not otherwise
35 requested one.
36
37 Normally this is set to "Null", which loads
38 Metrics::Any::Adapter::Null. By overriding this to a different value,
39 a default adapter can be loaded without modifying the program. This may
40 be useful for example, when running unit tests:
41
42 $ METRICS_ANY_ADAPTER=Stderr ./Build test
43
44 Additional arguments can be specified after a colon, separated by
45 commas or equals signs.
46
47 $ METRICS_ANY_ADAPTER=File:path=metrics.log ./program.pl
48
49 Note that if a program requests a specific adapter that will override
50 this variable.
51
52 A limited attempt is made at supporting nested arguments wrapped in
53 square brackets, to allow basic operation of the
54 Metrics::Any::Adapter::Tee adapter via this variable to itself pass
55 arguments into child adapters:
56
57 $ METRICS_ANY_ADAPTER=Tee:Prometheus,[File:path=metrics.log] perl ...
58
59 This should be considered a best-effort scenario useful for short-term
60 testing and debugging. For more complex requirements in your script or
61 program, it is better to use the import arguments directly as then any
62 perl data structures can be passed around.
