Micrometer Observation Documentation

This section describes the Micrometer integration.

Observability - Metrics

Below you can find a list of all metrics declared by this project.

Listener Observation

Observation for Rabbit listeners.

Metric name spring.rabbit.listener (defined by convention class RabbitListenerObservation$DefaultRabbitListenerObservationConvention). Type timer.

Metric name spring.rabbit.listener.active (defined by convention class RabbitListenerObservation$DefaultRabbitListenerObservationConvention). Type long task timer.

KeyValues that are added after starting the Observation might be missing from the *.active metrics.

Micrometer internally uses nanoseconds for the baseunit. However, each backend determines the actual baseunit. (i.e. Prometheus uses seconds)

Name of the enclosing class RabbitListenerObservation.

Table 1. Low cardinality Keys
Name	Description
`messaging.destination.name` (required)	The queue the listener is plugged to.
`messaging.rabbitmq.message.delivery_tag` (required)	The delivery tag. After deprecation this key is not exposed as a low cardinality tag.
`spring.rabbit.listener.id` (required)	Listener id.

Stream Listener Observation

Observation for Rabbit stream listeners.

Metric name spring.rabbit.stream.listener (defined by convention class RabbitStreamListenerObservation$DefaultRabbitStreamListenerObservationConvention). Type timer.

Metric name spring.rabbit.stream.listener.active (defined by convention class RabbitStreamListenerObservation$DefaultRabbitStreamListenerObservationConvention). Type long task timer.

KeyValues that are added after starting the Observation might be missing from the *.active metrics.

Micrometer internally uses nanoseconds for the baseunit. However, each backend determines the actual baseunit. (i.e. Prometheus uses seconds)

Name of the enclosing class RabbitStreamListenerObservation.

All tags must be prefixed with spring.rabbit.stream.listener prefix!

Table 2. Low cardinality Keys
Name	Description
`spring.rabbit.stream.listener.id` (required)	Listener id.

Stream Template Observation

Observation for `RabbitStreamTemplate`s.

Metric name spring.rabbit.stream.template (defined by convention class RabbitStreamTemplateObservation$DefaultRabbitStreamTemplateObservationConvention). Type timer.

Metric name spring.rabbit.stream.template.active (defined by convention class RabbitStreamTemplateObservation$DefaultRabbitStreamTemplateObservationConvention). Type long task timer.

KeyValues that are added after starting the Observation might be missing from the *.active metrics.

Micrometer internally uses nanoseconds for the baseunit. However, each backend determines the actual baseunit. (i.e. Prometheus uses seconds)

Micrometer internally uses nanoseconds for the baseunit. However, each backend determines the actual baseunit. (i.e. Prometheus uses seconds)

Name of the enclosing class RabbitTemplateObservation.

Table 4. Low cardinality Keys
Name	Description
