总结
运行一个
Kafka
集群需要付出很大的努力，为了让
Kafka
保持巅峰状态，需要做大量的配
置和维护。我们在这一章里介绍了
Kafka
的很多日常操作，比如经常会用到的主题管理和
客户端配置；也介绍了一些用于诊断问题的复杂操作，比如检查日志片段；最后还介绍了
一些不安全的操作，这些操作在特殊的情况下可以帮你解决问题。通过执行这些操作，你
就可以更好地管理
Kafka
集群。
当然，如果没有进行适当的监控，管理集群就是一个不可能完成的任务。第
10
章将会讨
论如何对
broker
和集群的健康状况以及操作进行监控，这样就可以知道
Kafka
的运行状态
了。我们也会提供一些有关客户端（包括生产者和消费者）监控的最佳实践。
