我已经使用以下 tomcat 参数启动了我的 springboot 应用程序-Dserver.tomcat.max-threads=400
-Dserver.tomcat.max-connections=4000我想监控繁忙的线程和繁忙的连接大小？springboot里面有内置解决方案吗？否则我需要获得 mbean 吗？

起初，我使用 Spring Boot Actuator 和 Micrometer。但它不显示 tomcat 线程利用率。所以我这样配置了application.yml。
server:
port: 3200
address: 0.0.0.0
tomcat:
max-threads: 4000
mbeanregistry:
enabled: true
我设置server.tomcat.mbeanregistry.enabled为真。然后 Tomcat 线程利用率显示在 /actuator/metrics 中。
这是我的输出。

您可以使用Spring Boot Actuator（/metrics 端点）来提供有关内存、堆、处理器、线程、加载的类、卸载的类、线程池等信息。
例如，此端点返回：
"threads.peak" : ..., "threads.daemon" : ..., "threads" : ...,
此外，如果需要，您可以使用 /threaddump 端点获取线程转储。
