Monitoring IBM MQ with java

How do I discover the Queue depth, and other metrics about queues, from IBM MQ using java with standard IBM MQ libraries?

Try out the below sample code snippet for fetching the queue depth.

String mqQMgr = "";
String mqQueue = "";
MQEnvironment.hostname = "";
MQEnvironment.port = "";
MQEnvironment.channel = "";    
MQEnvironment.properties.put(MQC.TRANSPORT_PROPERTY, MQC.TRANSPORT_MQSERIES);
MQQueueManager qMgr = new MQQueueManager(mqQMgr);
MQQueue destQueue = qMgr.accessQueue(mqQueue, openOptions);
int depth = destQueue.getCurrentDepth();
destQueue.close();
qMgr.disconnect();

A full code version (Change your parameters accordingly, like Bindings or client mode, options etc ) :

import com.ibm.mq.*;
public class QueueManager {
private final String host;
private final int port;
private final String channel;
private final String manager;
private final MQQueueManager qmgr;
public QueueManager(String host, int port, String channel, String manager) throws MQException {
this.host = host;
this.port = port;
this.channel = channel;
this.manager = manager;
this.qmgr = createQueueManager();
}
private MQQueueManager createQueueManager() throws MQException {
MQEnvironment.channel = channel;
MQEnvironment.port = port;
MQEnvironment.hostname = host;
MQEnvironment.properties.put(MQC.TRANSPORT_PROPERTY, MQC.TRANSPORT_MQSERIES);
return new MQQueueManager(manager);
}
// This method will return the Queue Depth
public int queueDepth(String queueName) {
int depth = -1;
int openOptions = MQC.MQOO_INQUIRE + MQC.MQOO_FAIL_IF_QUIESCING;
MQQueue queue = null;
try {
queue = qmgr.accessQueue(queueName, openOptions);
depth = queue.getCurrentDepth();
}
catch (MQException e)
{
System.out.println("CC=" +e.completionCode + " : RC=" + e.reasonCode);
}
finally {
try {
if (queue != null)
queue.close();
}
catch (MQException e) {
System.out.println("CC=" +e.completionCode + " : RC=" + e.reasonCode);
}
}
return depth;
}
