Class Method Details

.add_check(object_or_nil_with_block = nil, &block) ⇒ Object

Public: Add a pre-built or custom check to your status endpoint. These checks are used to test the state of the world of the application, and need only respond to ‘#call`.

Once added, the given check will be called and passed an instance of this checker. If everything is good, do nothing! If there is a problem, use ‘add_error` to add an error message to the checker.

Examples

Rapporteur.add_check { |checker|
  checker.add_error("Bad luck.") if rand(2) == 1
}

Returns the Checker instance. Raises ArgumentError if the given check does not respond to call.

Returns the Checker instance.
