The JMX support for MongoDB exposes the results of executing the 'serverStatus' command on the admin database for a single MongoDB server instance. It also exposes an administrative MBean, MongoAdmin which will let you perform administrative operations such as drop or create a database. The JMX features build upon the JMX feature set available in the Spring Framework. See here for more details.
Spring's Mongo namespace enables you to easily enable JMX functionality
Example 9.1. XML schema to configure MongoDB
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:mongo="http://www.springframework.org/schema/data/mongo" xsi:schemaLocation= "http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/data/mongo http://www.springframework.org/schema/data/mongo/spring-mongo-1.0.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd"> <beans> <!-- Default bean name is 'mongo' --> <mongo:mongo host="localhost" port="27017"/> <!-- by default look for a Mongo object named 'mongo' --> <mongo:jmx/> <context:mbean-export/> <!-- To translate any MongoExceptions thrown in @Repository annotated classes --> <context:annotation-config/> <bean id="registry" class="org.springframework.remoting.rmi.RmiRegistryFactoryBean" p:port="1099" /> <!-- Expose JMX over RMI --> <bean id="serverConnector" class="org.springframework.jmx.support.ConnectorServerFactoryBean" depends-on="registry" p:objectName="connector:name=rmi" p:serviceUrl="service:jmx:rmi://localhost/jndi/rmi://localhost:1099/myconnector" /> </beans>
This will expose several MBeans
AssertMetrics
BackgroundFlushingMetrics
BtreeIndexCounters
ConnectionMetrics
GlobalLoclMetrics
MemoryMetrics
OperationCounters
ServerInfo
MongoAdmin
This is shown below in a screenshot from JConsole
