Visão Geral

Este curso aborda metodologias, ferramentas e técnicas avançadas para diagnóstico e resolução de problemas em plataformas de mensageria e Event Streaming. O participante aprenderá a investigar falhas em brokers, producers, consumers, queues, topics, partitions, storage, networking, autenticação e processamento de mensagens. O curso utiliza uma abordagem sistemática de troubleshooting, incluindo análise de logs, métricas, traces, consumer lag, throughput, latency, recursos de infraestrutura e dependências externas. Também serão explorados cenários práticos envolvendo Apache Kafka, RabbitMQ e Apache Pulsar, além de ambientes Kubernetes e Cloud.
