PSGI extension for interaction with monitoring

[robrwo]

I am working on some middleware that sends data to statsd, and would like to suggest using the key `psgix.monitor.statsd' for a statsd client that supports some standard methods.

[robrwo]

The module Plack::Middleware::Statsd sets/uses the psgix.monitor.statsdkey, which is also used by Catalyst::Plugin::Statsd.

It is expected that the object would support the common methods that Net::Statsd::Client or Net::Statsd::Tiny do:

• increment
• decrement
• timing_ms
• set_add
• gauge

psgix namespace is used for extensions shared by multiple PSGI server implementations.

The use case doesn't seem to require the psgix namespace, you can rather implement in your own namespace.
