| # You can create a connection to the SCMB very easily; your client object has everything | ||
| # the ::new_connection method needs to connect: | ||
| connection = OneviewSDK::SCMB.new_connection(@client) | ||
|
|
||
| # The ::new_connection method above does some setup tasks for you if needed, including | ||
| # creating a keypair for the default RabbitMQ user on OneView (rabitmq_readonly) | ||
|
|
||
| # Now you can create a queue that will be used to subscribe to messages. By default it | ||
| # will use the least specific routing key possible, so it will respond to ALL events: | ||
| q = OneviewSDK::SCMB.new_queue(connection) | ||
| puts "Created queue: #{q.name}" | ||
|
|
||
| # More likely, you'll want to subscribe to a smaller subset of events. For example, to | ||
| # subscribe to only messages posted when an ethernet network is created: | ||
| eth_create_q = OneviewSDK::SCMB.new_queue(connection, 'scmb.ethernet-networks.Created.#') | ||
| puts "Created queue: #{eth_create_q.name}\n\n" | ||
|
|
||
| # Here are some other routing key options for the ethernet network resource: | ||
| # 'scmb.ethernet-networks.#' -> Any ethernet network event | ||
| # 'scmb.ethernet-networks.Updated.<resource_uri>' -> Only when a specific network is updated | ||
|
|
||
| puts 'Subscribing to OneView messages. To exit, press Ctrl + c' | ||
|
|
||
| # Then when you're ready to start listening, subscribe to a queue. Here we'll just print | ||
| # out the message, but you'll insert your own logic in the block below. Also, see | ||
| # http://rubybunny.info/articles/queues.html for more details & options. | ||
| q.subscribe(block: true) do |_delivery_info, _properties, payload| | ||
| data = JSON.parse(payload) rescue payload | ||
| puts 'Received message with payload:' | ||
| pp data # Pretty print | ||
| puts "\n#{'=' * 50}\n" | ||
