The Spring Boot application metrics are also ingested by Prometheus using Spring Actuator and micrometer. Micrometer documentation states that: Timers are intended for measuring short-duration latencies, and the frequency of such events. Doing this will help us keep track of kafka’s producer and consumer performance and also will help us to see the impact of specific Prometheus requires a Service Discovery component to automatically probe the configured endpoint for metrics. 44. 3. I saw in another project that they have a load more: kafka_producer_request_latency_avg, kafka_producer_record_retry_total, etc. Alertmanager raises alerts based on configured rules, and optionally notifies a Slack channel.
