The API I want Assembler to provide

api.rb

# This is for building a JSON request to the monitoring service
MonitorClient.group(name: 'my group') do |g|
  g.add_watch(name: 'Something fragile') do |w|
    w.description = 'information about watch'
    w.docs = 'http://triage.com'
    w.owners = ['ryan@example.com']
    w.metric = MonitorClient::Metric::Graphite.new(target: 'foo.bar.baz')
    w.policy = never_be_zero
    
    w.add_action MonitorClient::Action::Email.new
    w.add_action MonitorClient::Action::Pagerduty.new
  end
end.upload

# So an alternate form that doesn't require anything special could look like this
MonitorClient.group(name: 'my group', watches: []) do |g|
  g.watches << MonitorClient::Watch.new(name: 'Something fragile', actions: []) do |w|
    w.description = 'information about watch'
    w.docs = 'http://triage.com'
    w.owners = ['ryan@example.com']
    w.metric = MonitorClient::Metric::Graphite.new(target: 'foo.bar.baz')
    w.policy = never_be_zero
    
    w.actions << MonitorClient::Action::Email.new
    w.actions << MonitorClient::Action::Pagerduty.new
  end
end
