This assumes you are able to connect to WebMethods Broker Server in Java.

Here is an example class that can be used to get the Broker server statistics for the Broker server on server1.example.com.

import COM.activesw.api.client.*;

public class Main {
	public static void main(String[] args) {
		try {				
			BrokerServerClient server_client = new BrokerServerClient("server1.example.com", null);
			System.out.println("server_client = " + server_client);

			BrokerEvent getStats = admin_client.getStats();
			System.out.println(getStats);	

		} catch (BrokerException ex) {
			System.out.println("Caught the following exception: " + ex);
		}
	}	
}

Or like this, using getBrokerStats.

import COM.activesw.api.client.*;

public class Main {
	public static void main(String[] args) {
		try {				
			BrokerServerClient server_client = new BrokerServerClient("server1.example.com", null);
			System.out.println("server_client = " + server_client);

			BrokerEvent getBrokerStats = admin_client.getBrokerStats();
			System.out.println(getBrokerStats);	

		} catch (BrokerException ex) {
			System.out.println("Caught the following exception: " + ex);
		}
	}	
}

Or like this, using getUsageStats.

import COM.activesw.api.client.*;

public class Main {
	public static void main(String[] args) {
		try {				
			BrokerServerClient server_client = new BrokerServerClient("server1.example.com", null);
			System.out.println("server_client = " + server_client);

			BrokerEvent getUsageStats = admin_client.getUsageStats();
			System.out.println(getUsageStats);	

		} catch (BrokerException ex) {
			System.out.println("Caught the following exception: " + ex);
		}
	}	
}

If the request is successful, something like this should be returned.
