Note

The Timeline SQL Store either stores timeline messages in the database, or consumes timeline events from the queue. When the configuration below is enabled, only timeline events are consumed, no timeline messages are saved to the database directly. So if you enable this configuration, be sure to also enable the Timeline Event Publisher Component, otherwise no timeline information is saved anywhere.

The queue configuration can be configured using a default queue (using blueriq.default.rabbitmq.* in the application.properties). When it is needed, it can be overruled using the configuration below.

Also the timeline events queue has a default, and can be overruled by configuration when needed.

# RabbitMQ configuration
blueriq.timeline.event.listener.amqp.rabbitmq.host=localhost
blueriq.timeline.event.listener.amqp.rabbitmq.port=5672
blueriq.timeline.event.listener.amqp.rabbitmq.virtualHost=/
blueriq.timeline.event.listener.amqp.rabbitmq.username=guest
blueriq.timeline.event.listener.amqp.rabbitmq.password=guest
blueriq.timeline.event.listener.amqp.rabbitmq.queueNames=trace

blueriq.timeline.event.listener.amqp.concurrency.max-concurrent-consumers=1
blueriq.timeline.event.listener.amqp.concurrency.concurrent-consumers=1

# Enable consumer functionality
blueriq.timeline.event.listener.amqp.enabled=true
Note

In certain circumstances it is possible that an error happens while consuming the timeline event. Because of the workings of RabbitMQ, this will result in an endless loop where it tries to re-send the timeline event until it is correctly consumed. To prevent this, a republish mechanism is added with Blueriq 15.7. This mechanism sends timeline events to a dead-letter-queue when an error occurs. This will prevent the creation of the endless loop. For information see Configuring RabbitMQ
