liteflow 线程池管理
liteflowdynamictp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-liteflow</artifactId>
<version>1.1.9</version>
</dependency>
SpringBoot3x 用此依赖
<dependency>
<groupId>org.dromara.dynamictp</groupId>
<artifactId>dynamic-tp-spring-boot-starter-adapter-liteflow</artifactId>
<version>1.1.9-3.x</version>
</dependency>
- 配置文件中配置 brpc 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
liteflowTp:
- threadPoolName: liteflowTp#LiteFlowDefaultWhenExecutorBuilder
corePoolSize: 10
maximumPoolSize: 20
keepAliveTime: 60
runTimeout: 200
queueTimeout: 100
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, liteflowTp init end, executors: {liteflowTp#LiteFlowDefaultWhenExecutorBuilder=ExecutorWrapper(threadPoolName=liteflowTp#LiteFlowDefaultWhenExecutorBuilder, executor=java.util.concurrent.ThreadPoolExecutor@162475a[Running, pool size = 0, 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 adapter, [liteflowTp#LiteFlowDefaultWhenExecutorBuilder] refreshed end, changed keys: [corePoolSize, maxPoolSize], corePoolSize: [17 => 100], maxPoolSize: [500 => 200], keepAliveTime: [60 => 60]
提示
- 线程池名称规则:liteflowTp + "#" + 线程池构建者的 Class 类名(可以在启动日志找输出的线程池名称)
- liteflow 线程池享有动态调参、监控、通知告警完整的功能
