在运行时访问JBoss池统计信息

Question

我在我的项目中使用JBoss EAP6.2。我已经将无状态bean (slsb-strict-max- pool )的池大小配置为x。我可以在线程转储中看到一些线程在等待一些池化实例。

现在我想在运行时监控每个@Stateless bean使用的池大小。那么有没有办法通过一些MXBean来访问这些信息呢？所以我可以在某个地方显示@Stateless bean已经分配了y个池化的实例？

谢谢，Rokko

好吧，如果你已经分析过线程转储，我想你应该了解jboss-cli。它显示了EJB组件的运行时指标。例如：

/deployment=ProjectEAR.ear/subdeployment=ProjectWAR.war/subsystem=ejb3/stateless-session-bean=StatelessEJBName  :read-resource(include-runtime=true, recursive=true) 
{
"outcome" => "success",
"result" => {
    "component-class-name" => "StatelessEJBName",
    "declared-roles" => [],
    "execution-time" => 0L,
    "invocations" => 0L,
    "methods" => {},
    "peak-concurrent-invocations" => 0L,
    "pool-available-count" => 20,
    "pool-create-count" => 1,
    "pool-current-size" => 1,
    "pool-max-size" => 20,
    "pool-name" => "slsb-strict-max-pool",
    "pool-remove-count" => 0,
    "run-as-role" => undefined,
    "security-domain" => "other",
    "timers" => [],
    "wait-time" => 0L,
    "service" => undefined
} }

还不是很清楚，您是想只获取运行时EJB统计信息，还是从应用程序中以编程方式获取EJB统计信息？
