Observability - Metrics

Below you can find a list of all metrics declared by this project.spring-doc.cn

Listener Observation

Observation for Apache Kafka listeners.spring-doc.cn

Metric name spring.kafka.listener (defined by convention class KafkaListenerObservation$DefaultKafkaListenerObservationConvention). Type timer.spring-doc.cn

Metric name spring.kafka.listener.active (defined by convention class KafkaListenerObservation$DefaultKafkaListenerObservationConvention). Type long task timer.spring-doc.cn

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 KafkaListenerObservation.spring-doc.cn

All tags must be prefixed with spring.kafka.listener prefix!
Table 1. Low cardinality Keys

spring.kafka.listener.id (required)spring-doc.cn

Listener id (or listener container bean name).spring-doc.cn

Template Observation

Metric name spring.kafka.template (defined by convention class KafkaTemplateObservation$DefaultKafkaTemplateObservationConvention). Type timer.spring-doc.cn
