motan 线程池管理

使用步骤

1. 引入下述依赖

   <dependency>
        <groupId>cn.dynamictp</groupId>
        <artifactId>dynamic-tp-spring-boot-starter-adapter-motan</artifactId>
        <version>1.1.2</version>
    </dependency>

2. 配置文件中配置 motan 线程池

spring:
  dynamic:
    tp:
      enabled: true
      enabledCollect: true          # 是否开启监控指标采集，默认false
      collectorTypes: micrometer    # 监控数据采集器类型（logging | micrometer | internal_logging），默认micrometer
      monitorInterval: 5            # 监控时间间隔（报警判断、指标采集），默认5s
      motanTp:                                      # motan server 线程池配置
        - threadPoolName: motanTp#8002
          corePoolSize: 100
          maximumPoolSize: 200
          keepAliveTime: 60

3. 启动日志

服务启动看到有如下日志输出说明接入成功，如果开启了通知，同时会推送参数修改通知

DynamicTp adapter, motan server executors init end, executors: {motanTp#8002=ExecutorWrapper(threadPoolName=motanTp#8002, executor=com.weibo.api.motan.transport.netty.StandardThreadExecutor@174b233[Running, pool size = 20, active threads = 0, queued tasks = 0, completed tasks = 0], threadPoolAliasName=null, notifyItems=[NotifyItem(platforms=null, enabled=true, type=liveness, threshold=70, interval=120, clusterLimit=1), NotifyItem(platforms=null, enabled=true, type=change, threshold=0, interval=1, clusterLimit=1), NotifyItem(platforms=null, enabled=true, type=capacity, threshold=70, interval=120, clusterLimit=1)], notifyEnabled=true)}
DynamicTp motanTp adapter, [motanTp#8002] refreshed end, changed keys: [corePoolSize], corePoolSize: [20 => 100], maxPoolSize: [200 => 200], keepAliveTime: [60 => 60]

提示

1. 线程池名称规则：motanTp + "#" + URL 端口号（可以在启动日志找输出的线程池名称）
2. motan 线程池享有动态调参、监控、通知告警完整的功能
3. motan 线程池通知告警项有（调参通知、活性告警、队列容量告警），可通过 notifyItems 自定义配置项值，默认全部开启
4. 只支持 server 端线程池管理
