             Summary: Not Able to Change Zookeeper Logging via JMX Call
                 Key: ZOOKEEPER-3070
                 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-3070
             Project: ZooKeeper
          Issue Type: Improvement
          Components: jmx
    Affects Versions: 3.4.5
         Environment: Using Java 8 for writing standalone code to update the MBeans in zookeeper which is running in Windows machine for POC purpose.

Zookeeper Version is : 3.4.5
            Reporter: jahar

Hi,

I wanted to change the logging level of zookeeper dynamically via a JMX call programmatically. Apache Zookeeper official page specifies that it is possible to change the Mbeans via JMX calls and I have verified this through JConsole also.

But the problem is that I am not able to update the Mbeans related to log4j through my code. I do see an API which can be used to access the Mbeans related to Object "org.apache.ZooKeeperService:name0=StandaloneServer_port-1" below is the screengrab of Jconsole and my code:

Here goes my Code:
{quote}public static void main(String[] args) throws Exception
 {
 JMXServiceURL url = new JMXServiceURL("service:jmx:rmi:///jndi/rmi://localhost:2167/jmxrmi");
 JMXConnector jmxConnector = JMXConnectorFactory.connect(url);
 MBeanServerConnection mbeanServerConnection = jmxConnector.getMBeanServerConnection();
 ObjectName mbeanName = new ObjectName("org.apache.ZooKeeperService:name0=StandaloneServer_port-1");
 ZooKeeperServerMXBean newProxyInstance = MBeanServerInvocationHandler.newProxyInstance(mbeanServerConnection,
 mbeanName, ZooKeeperServerMXBean.class, true);
 System.out.println(newProxyInstance.getClientPort());
 }
{quote}
 

 

I dont see any API which can be used to access and update the log4J Mbeans e.g. "root". What I want to achieve is to update the logging of zookeeper without taking a restart.

Please advice if some API is exposed to achieve this.
