Gather a graph of info about a component, it's consumers, handlers, etc, into a buffer. Output the contents at component startup.

For example:

Starting Component: TaxonomyDataComponent::Start (lib/taxonomy_data_component/start.rb)
Name: (none)

  Starting consumer: TaxonomyDataComponent::Consumers::Taxonomy::Events
  Category: taxonomy
  Identifier: (none)
  Position: 0

    Handler: TaxonomyDataComponent::Handlers::Taxonomy::Events
	Messages: Taxonomize, DataGenerated, Taxonomized

Started Component: TaxonomyDataComponent::Start
ProcessID: 65674

Possibly an implementation of the form:

info = Consumer::Info.get(SomeConsumer)

output = info.to_s
puts output

# Or:
info = Consumer::Info.get(SomeConsumer)

# Or:

# Where the signature of dump is:

The same pattern would be represented in lower parts of the stack, from host, to consumers, handlers, and maybe even messages.


  • Lower the precedence of the position store log output so that it doesn't print before the component dump
  • Make the dump on by default, but able to be deactivated via an environment variable
  • If the info dump is deactivated, set the log level of the component info logs to the highest level. Otherwise, log them at the info or debug level
    • Decision needed on what level to log the info at when the info dump is activated
