playframework - 如何在 Play Framework 中检查事件和排队的作业数？

Question

我的应用程序必须通过 HTTP API 报告其作业负载。 “Play 状态”命令似乎提供了我需要的信息:

Jobs execution pool:
~~~~~~~~~~~~~~~~~~~
Pool size: 0
Active count: 0
Scheduled task count: 0
Queue size: 0

如何在 Play Framework Controller 中访问此信息？

Answer 1

看看 JobsPlugin.java，有一个静态的 executor 属性，getStatus() 方法显示了值的来源:
https://github.com/playframework/play/blob/master/framework/src/play/jobs/JobsPlugin.java

    out.println("Jobs execution pool:");
    out.println("~~~~~~~~~~~~~~~~~~~");
    out.println("Pool size: " + JobsPlugin.executor.getPoolSize());
    out.println("Active count: " + JobsPlugin.executor.getActiveCount());
    out.println("Scheduled task count: " + JobsPlugin.executor.getTaskCount());
    out.println("Queue size: " + JobsPlugin.executor.getQueue().size());
