RabbitMQ is an open-source message-broker software (sometimes called message-oriented middleware) that originally implemented the Advanced Message Queuing Protocol (AMQP) and has since been extended with a plug-in architecture to support Streaming Text Oriented Messaging Protocol (STOMP), MQ Telemetry Transport (MQTT), and other protocols.
Simple plugin design that allows users to easily develop their own service checks depending on needs, by using the tools of choice (shell scripts, C++, Perl, Ruby, Python, PHP, C#, etc.) Ability to calculate KPIs from State and performance data in the Shinken core to create new services and performance data; System external interfaces

The windowing system places messages indicating user or other events, such as timer ticks or messages sent by other threads, into the message queue. The GUI application removes these events one at a time by calling a routine called getNextEvent() or similar in an event loop , and then calling the appropriate application routine to process that ...
Examples of such messaging services include: Skype, Facebook Messenger, Google Hangouts (subsequently Google Chat), Telegram, ICQ, Element, Slack, Discord, etc. Users have more options as usernames or email addresses can be used as user identifiers, besides phone numbers. Unlike the phone-based model, user accounts on a multi-device model are ...
Sequence diagram for depicting the Message Broker pattern. A message broker (also known as an integration broker or interface engine [1]) is an intermediary computer program module that translates a message from the formal messaging protocol of the sender to the formal messaging protocol of the receiver.
AMQP is a binary application layer protocol, designed to efficiently support a wide variety of messaging applications and communication patterns. It provides flow controlled, [3] message-oriented communication with message-delivery guarantees such as at-most-once (where each message is delivered once or never), at-least-once (where each message is certain to be delivered, but may do so ...
Message-oriented middleware (MOM) is software or hardware infrastructure supporting sending and receiving messages between distributed systems.Message-oriented middleware is in contrast to streaming-oriented middleware where data is communicated as a sequence of bytes with no explicit message boundaries.
