11.2. Web Container metrics
- ActiveSessionsLoadMetric
- Requires an explicit capacity.
- Uses SessionLoadMetricSource to query session managers
- Analogous to method=S in mod_jk
For example:<bean name="ActiveSessionsLoadMetric" class="org.jboss.modcluster.load.metric.impl.ActiveSessionsLoadMetric" mode="On Demand"> <annotation>@org.jboss.aop.microcontainer.aspects.jmx.JMX(name="jboss.web:service=ActiveSessionsLoadMetric",exposedInterface=org.jboss.modcluster.load.metric.LoadMetricMBean.class)</annotation> <constructor> <parameter><inject bean="SessionLoadMetricSource"/></parameter> </constructor> <property name="capacity">1000</property> </bean> <bean name="SessionLoadMetricSource" class="org.jboss.modcluster.load.metric.impl.SessionLoadMetricSource" mode="On Demand"> <constructor> <parameter class="javax.management.MBeanServer"><inject bean="JMXKernel" property="mbeanServer"/></parameter> </constructor> </bean> - BusyConnectorsLoadMetric
- Returns the percentage of connector threads from the thread pool that are busy servicing requests
- Uses ThreadPoolLoadMetricSource to query connector thread pools
- Analogous to method=B in mod_jk
For example:<bean name="BusyConnectorsLoadMetric" class="org.jboss.modcluster.load.metric.impl.BusyConnectorsLoadMetric" mode="On Demand"> <annotation>@org.jboss.aop.microcontainer.aspects.jmx.JMX(name="jboss.web:service=BusyConnectorsLoadMetric",exposedInterface=org.jboss.modcluster.load.metric.LoadMetricMBean.class)</annotation> <constructor> <parameter><inject bean="ThreadPoolLoadMetricSource"/></parameter> </constructor> </bean> <bean name="ThreadPoolLoadMetricSource" class="org.jboss.modcluster.load.metric.impl.ThreadPoolLoadMetricSource" mode="On Demand"> <constructor> <parameter class="javax.management.MBeanServer"><inject bean="JMXKernel" property="mbeanServer"/></parameter> </constructor> </bean> - ReceiveTrafficLoadMetric
- Returns the incoming request traffic in KB/sec
- Requires an explicit capacity
- Uses RequestProcessorLoadMetricSource to query request processors
- Analogous to method=T in mod_jk
For example:<bean name="ReceiveTrafficLoadMetric" class="org.jboss.modcluster.load.metric.impl.ReceiveTrafficLoadMetric" mode="On Demand"> <annotation>@org.jboss.aop.microcontainer.aspects.jmx.JMX(name="jboss.web:service=ReceiveTrafficLoadMetric",exposedInterface=org.jboss.modcluster.load.metric.LoadMetricMBean.class)</annotation> <constructor> <parameter class="org.jboss.modcluster.load.metric.impl.RequestProcessorLoadMetricSource"><inject bean="RequestProcessorLoadMetricSource"/></parameter> </constructor> <property name="capacity">1024</property> </bean> <bean name="RequestProcessorLoadMetricSource" class="org.jboss.modcluster.load.metric.impl.RequestProcessorLoadMetricSource" mode="On Demand"> <constructor> <parameter class="javax.management.MBeanServer"><inject bean="JMXKernel" property="mbeanServer"/></parameter> </constructor> </bean> - SendTrafficLoadMetric
- Returns the outgoing request traffic in KB/sec
- Requires an explicit capacity
- Uses RequestProcessorLoadMetricSource to query request processors
- Analogous to method=T in mod_jk
For example:<bean name="SendTrafficLoadMetric" class="org.jboss.modcluster.load.metric.impl.SendTrafficLoadMetric" mode="On Demand"> <annotation>@org.jboss.aop.microcontainer.aspects.jmx.JMX(name="jboss.web:service=SendTrafficLoadMetric",exposedInterface=org.jboss.modcluster.load.metric.LoadMetricMBean.class)</annotation> <constructor> <parameter class="org.jboss.modcluster.load.metric.impl.RequestProcessorLoadMetricSource"><inject bean="RequestProcessorLoadMetricSource"/></parameter> </constructor> <property name="capacity">512</property> </bean> - RequestCountLoadMetric
- Returns the number of requests/sec
- Requires an explicit capacity
- Uses RequestProcessorLoadMetricSource to query request processors
- Analogous to method=R in mod_jk
For example:<bean name="RequestCountLoadMetric" class="org.jboss.modcluster.load.metric.impl.RequestCountLoadMetric" mode="On Demand"> <annotation>@org.jboss.aop.microcontainer.aspects.jmx.JMX(name="jboss.web:service=RequestCountLoadMetric",exposedInterface=org.jboss.modcluster.load.metric.LoadMetricMBean.class)</annotation> <constructor> <parameter class="org.jboss.modcluster.load.metric.impl.RequestProcessorLoadMetricSource"><inject bean="RequestProcessorLoadMetricSource"/></parameter> </constructor> <property name="capacity">1000</property> </bean>
