我正在尝试使用asadmin接口来监视GlassFish 3.1.1上的线程池。我正在执行以下命令：
asadmin get -m server.network.my-listener.thread-pool.*
我正在收回数据，但大多数都有lastsampletime = -1（因此相关数据为零;并且没有价值）。
注意：我也尝试过REST接口，我相信asadmin委托给它，以及JMX接口。同样的问题：大部分数据都有lastsampletime = -1。
我已经将所有模块的监控设置为HIGH。我错过了什么？

似乎重新部署我的应用程序是监控实际获取值所必需的。也许我错误地解释了手册，但它似乎表明不需要重新启动/重新部署：
Oracle GlassFish Server 3.1 Administration Guide
另外，下面显示没有监控数据，这很奇怪：
asadmin get -m server.thread-pools.thread-pool.http-thread-pool.*
相反，您必须通过特定的网络侦听器，如：
asadmin get -m server.network.http-listener-2.thread-pool.*
令我惊讶的是，启用线程池监视不足以查看线程池统计信息。您还必须启用http服务监控：
asadmin enable-monitoring
asadmin set server.monitoring-service.module-monitoring-levels.thread-pool=HIGH
asadmin set server.monitoring-service.module-monitoring-levels.http-service=HIGH

这就是你应该做的所有事情。
HIGH。asadmin get -m *instancename*.network.*listener*.thread-pool.* 看起来您正在监控DAS，因为您使用的是asadmin get -m server.network.my-listener.thread-pool.*.
我向DAS部署了一个简单的战争并发出了一堆http请求。我看到corethreads-count和maxthreads-count的最后一个采样时间为-1。剩下的统计数据包含实际的最后采样时间。
asadmin get -m "server.network.http-listener-1.thread-pool.*"
server.network.http-listener-1.thread-pool.corethreads-count = 0

要立即启用监控而不重启，请使用enable-monitoring命令
enable-monitoring
enable-monitoring --modules jvm=LOW
enable-monitoring --modules thread-pool=HIGH
enable-monitoring --modules http-service=HIGH
enable-monitoring --modules jdbc-connection-pool=HIGH
诀窍是线程池和http服务模块必须具有高级别才能获得监控信息。
