CreateRabbitMqExchanges

Creates one or more RabbitMQ exchanges with the configured durability, auto-delete, and arguments.

What It Does

Creates RabbitMQ exchanges through the AMQP connection defined in the probe configuration.

It is a setup probe for scenarios that need the messaging topology to exist before publishers or consumers start.

YAML Example

Sessions:
  - Name: ProbeSession
    Probes:
      - Name: CreateRabbitMqExchangesProbe
        Probe: CreateRabbitMqExchanges
        ProbeConfiguration:
          UseGlobalDict: true
          Host: rabbitmq.local
          Port: 5672
          Username: guest
          Password: guest
          VirtualHost: /
          Exchanges:
            - Name: orders.exchange
              Type: Direct
              Durable: true
              AutoDelete: false

What This Configuration Does

This configuration creates a durable direct exchange named orders.exchange in the / virtual host.

Because AutoDelete is false, the exchange remains in place until it is deleted explicitly.

Global Dictionary Behavior

With UseGlobalDict: true, missing broker connection fields are first resolved from RabbitMq/AmqpDefaults, and missing Exchanges can then be resolved from RabbitMq/Recovery/Exchanges when a paired delete probe saved recovery state earlier in the same execution and session.

Any key that is present locally still wins, even when the local value is false, 0, an empty string, or an empty collection. This makes the probe useful when you want to recreate exchanges that were deleted earlier in the same recovery flow. When UseGlobalDict is false, the probe ignores both aliases and keeps the current local-only behavior.
