motan 线程池管理
motanrpcdynamictp大约 2 分钟
使用步骤
- 引入下述依赖
SpringBoot1x、2x 用此依赖
<dependency>
<groupId>org.dromara.dynamictp</groupId>
<artifactId>dynamic-tp-spring-boot-starter-adapter-motan</artifactId>
<version>1.1.9.1</version>
</dependency>
SpringBoot3x 用此依赖
<dependency>
<groupId>org.dromara.dynamictp</groupId>
<artifactId>dynamic-tp-spring-boot-starter-adapter-motan</artifactId>
<version>1.1.9.1-3.x</version>
</dependency>
- 配置文件中配置 motan 线程池
spring:
dynamic:
tp:
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 | JMX),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
runTimeout: 200
queueTimeout: 100
platformIds: [1,2] # 通知报警平台id,不配置默认拿上层platforms配置的所有平台
notifyItems: # 报警项,不配置自动会按默认值配置(变更通知、容量报警、活性报警、拒绝报警、任务超时报警)
- type: change
enabled: true
- type: capacity # 队列容量使用率,报警项类型,查看源码 NotifyTypeEnum枚举类
enabled: true
threshold: 80 # 报警阈值,默认70,意思是队列使用率达到70%告警
platformIds: [2] # 可选配置,本配置优先级 > 所属线程池platformIds > 全局配置platforms
interval: 120 # 报警间隔(单位:s),默认120
- type: liveness # 线程池活性
enabled: true
threshold: 80 # 报警阈值,默认 70,意思是活性达到70%告警
- type: reject # 触发任务拒绝告警
enabled: true
threshold: 100 # 默认阈值10
- type: run_timeout # 任务执行超时告警
enabled: true
threshold: 100 # 默认阈值10
- type: queue_timeout # 任务排队超时告警
enabled: true
threshold: 100 # 默认阈值10
- 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
- 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)
- motan 线程池享有动态调参、监控、通知告警完整的功能
