[jira] Commented: (DBCP-292) Adds an mbean for exposing metrics
around a BasicDataSource via JMX
[ https://issues.apache.org/jira/browse/DBCP-292?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12839120#action_12839120 ]
Alexandru Ionita commented on DBCP-292:
---------------------------------------
When registering the bean org.apache.commons.dbcp.BasicDataSource directly into Spring's MBeanExporter, you get the bean registered in the JMX stack.
What I was observing is that by each Refresh button hit in the JMX jconsole, the NumActive is increased with 2 !!! Basically, the jconsole is consuming two connections from the pool (don't know why) for each refresh without releasing them.

> The attached patch adds an mbean that exposes the following metrics of a BasicDataSource via jmx: numActive, numIdle, maxActive, maxIdle, minIdle & maxWait.
> I have put it in a new package: org.apache.commons.dbcp.management but feel free to put it in any package you see fit.
> If using Spring the bean can be configured a little something like this:
> <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
> ...
> </bean>
> <bean id="dataSourceMBean" class="org.apache.commons.dbcp.management.BasicDataSourceMBean">
> <constructor-arg ref="dataSource"/>
> </bean>
> <bean id="mbeanExporter" class="org.springframework.jmx.export.MBeanExporter">
> <property name="beans">
> <map>
> <entry key="DBCP:name=dataSource" value-ref="dataSourceMBean"/>
> </map>
> </property>
> </bean>
