尝试制作一个非常简单的 jython 脚本来从 websphere 获取基本的 PMI 数据。获取诸如空闲堆等 JVM 数据很简单（并且有效）

perfName = AdminControl.completeObjectName ('type=Perf,process=PTEIRMW_APPSERVER801,*')
perfOName = AdminControl.makeObjectName (perfName)
jvmName = AdminControl.completeObjectName ('type=JVM,process=PTEIRMW_APPSERVER801,*')
params = [AdminControl.makeObjectName (jvmName), java.lang.Boolean ('false')]
sigs = ['javax.management.ObjectName', 'java.lang.Boolean']
AdminControl.invoke_jmx (perfOName, 'getStatsObject', params, sigs)

但后来我尝试为 WebContainer 线程池做类似的事情，但它失败了

threadPoolName = AdminControl.completeObjectName('name=WebContainer,type=ThreadPool,process=PTEIRMW_APPSERVER801,*')
threadPoolOName = AdminControl.makeObjectName (threadPoolName)
params = [AdminControl.makeObjectName (threadPoolName), java.lang.Boolean ('false')]
sigs = ['javax.management.ObjectName', 'java.lang.Boolean']
AdminControl.invoke_jmx (threadPoolOName, 'getStatsObject', params, sigs)

错误是

WASX7015E: 异常运行命令：“AdminControl.invoke_jmx (threadPoolOName, 'getStatsObject', params, sigs)”；异常信息：javax.management.MBeanException javax.management.ServiceNotFoundException：操作getStatsObject不在ModelMBeanInfo中

有任何想法吗？我特别只想要 WebContainer 线程池（最好只有活动线程......但我可以稍后过滤掉它）

您需要stats从该 MBean 检索属性：

on = AdminControl.queryNames('*,name=WebContainer,type=ThreadPool,process=PTEIRMW_APPSERVER801')
print AdminControl.getAttribute_jmx(AdminControl.makeObjectName(on), 'stats')

相同的功能，这次使用 WDR 库 ( http://wdr.github.io/WDR/ )

print getJMXMBean1(type='ThreadPool', name='WebContainer', process='PTEIRMW_APPSERVER801').stats

坦白：我是 WDR 的贡献者之一。

答案结果如下（清理和更通用的版本）：

#Get the AppServer from parameter
appServer = sys.argv[0]

perfName = AdminControl.completeObjectName ('type=Perf,process='+appServer+',*')
perfOName = AdminControl.makeObjectName (perfName)
sigs = ['javax.management.ObjectName', 'java.lang.Boolean']

# Getting the JVM Data
jvmName = AdminControl.completeObjectName ('type=JVM,process='+appServer+',*')
params = [AdminControl.makeObjectName (jvmName), java.lang.Boolean ('false')]
print AdminControl.invoke_jmx (perfOName, 'getStatsObject', params, sigs)

# Getting the threadpool data

threadPoolName = AdminControl.completeObjectName('name=WebContainer,type=ThreadPool,process='+appServer+',*')
params = [AdminControl.makeObjectName (threadPoolName), java.lang.Boolean ('false')]
print AdminControl.invoke_jmx (perfOName, 'getStatsObject', params, sigs)

但我也测试了@Martin Plonkas 的答案，它也有效
