Question

如何启用此处列出的ExecutorServiceMetrics？

https://github.com/micrometer-metrics/micrometer/blob/master/micrometer-core/src/main/java/io/micrometer/core/instrument/binder/jvm/ExecutorServiceMetrics.java

SpringBoot版本：2.1.2。发布

在/ actuator / metrics下，我可以看到jvm和其他一些现成的自动配置的指标，但看不到执行者指标。

我尝试过设置，但是没有运气。

management:
  metrics:
    enable.executor: true

感谢您的帮助。

Answer 1

我能够在Spring Boot 2.1.2.RELEASE应用程序中获取ExecutorServiceMetrics报告指标，除了创建受监视的ExecutorService bean之外，无需做其他任何事情。我无需在application.yml或application.properties上添加任何内容即可完成这项工作。

示例：

@Configuration
public class ExecutorConfig {

    @Bean
    public ExecutorService executorService(final MeterRegistry registry) {
        return ExecutorServiceMetrics.monitor(registry, Executors.newFixedThreadPool(20), "my executor", Tags.of("key", "value"));
    }
}

然后，只需将executorService bean连接到组件中，然后将任务提交到该executorService bean。

Answer 2

我发现，如果要使用Spring Boot锁定它，则必须手动进行操作。我正在使用Spring Boot 2.2.9.RELEASE。

使用“ applicationTaskExecutor” Bean创建一个ExecutorServiceMetrics Bean（这样，您将获得之前已配置的任何Bean大小）。它会自动绑定。

类似的东西：

@Bean
@ConditionalOnMissingBean
public ExecutorServiceMetrics executorServiceMetrics(@Qualifier("applicationTaskExecutor")                                                             ThreadPoolTaskExecutor applicationTaskExecutor) {
    return new ExecutorServiceMetrics(applicationTaskExecutor.getThreadPoolExecutor(), "applicationTaskExecutor",
            Collections.emptyList());
}

这是我如何解决的（在Kotlin中）：

@EnableAsync
@Configuration
class AsyncConfig(
        private val taskExecutorBuilder: TaskExecutorBuilder,
        private val meterRegistry: MeterRegistry) : AsyncConfigurer {

    /**
     * Add monitoring of executor using micrometer.
     */
    override fun getAsyncExecutor(): Executor {
        // create executor based on default spring-boot properties
        val executor = taskExecutorBuilder.build()
        // we need to initialize it before calling monitor
        executor.initialize()
        // monitor the executor (so it is available in metrics) (must be wrapped)
        return ExecutorServiceMetrics.monitor(meterRegistry, executor.threadPoolExecutor, "AsyncExecutor", "async")
    }

}

所以基本上：

利用自动连接的TaskExecutorBuilder，以便根据spring.task.execution.*属性构建执行器
在ExecutorServiceMetrics中包装线程池执行程序（来自io.micrometer.core）以获取指标

请注意，要使其正常工作，您必须返回装饰好的执行器！

在此示例中，由于我给了前缀（async），因此可用的指标为：

async.executor
async.executor.active
async.executor.completed
async.executor.idle
async.executor.pool.core
async.executor.pool.max
async.executor.pool.size
async.executor.queue.remaining
async.executor.queued
