如何通过asadmin接口监控GlassFish线程池
如何通过asadmin接口监控GlassFish线程池
提问于 2011-11-03 03:07:24
我正在尝试使用asadmin接口来监控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.*我正在获取数据，但大多数数据的lastsampletime = -1 (因此相关数据为零；没有价值)。
注意:我还尝试了REST接口和JMX接口。同样的问题:大部分数据的lastsampletime = -1。
我已经将所有模块的监控设置为高。我遗漏了什么？

似乎需要重新部署我的应用程序才能让监控真正获得值。也许我对手册的理解有误，但它似乎表明不需要重新启动/重新部署：
Oracle GlassFish Server 3.1 Administration Guide
此外，奇怪的是，以下内容显示没有监控数据：
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程序，如：
asadmin get -m server.network.http-listener-2.thread-pool.*启用线程池监控还不足以查看线程池统计信息，这也让我感到惊讶。您还必须启用http-service监视：
asadmin enable-monitoring
asadmin set server.monitoring-service.module-monitoring-levels.thread-pool=HIGH
asadmin set server.monitoring-service.module-monitoring-levels.http-service=HIGHStack Overflow用户

这就是您需要做的全部工作。
对于要将应用程序monitor.
- Deploy到DAS、独立实例或群集并创建http-requests.
asadmin get -m *instancename*.network.*listener*.thread-pool.*
的DAS、独立实例或群集上的
- 模块，启用监视并将其设置为
HIGH
由于您使用的是asadmin get -m server.network.my-listener.thread-pool.*.，因此看起来您正在监视DAS
我在DAS上部署了一个简单的war，并发出了一堆http请求。我看到corethreads-count和maxthreads-count的上次采样时间为-1。剩余的统计数据具有实际的上次采样时间。

要在不重新启动的情况下立即启用监控，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-service模块必须具有高级别才能获得监控信息。
