Count number of messages
Hello,
in our infrastructure we are currently running Qpid java broker 0.12, with
a pretty standard configuration.
We have the need to connect our monitoring system to Qpid and count some
metrics. In particular, we would like to know the total number of messages
handled by all the queues at any given time.
What is the easiest way to implement it.
Thanks,
Mat

Alex,
I found that <statistics> was missing from my configuration, so I didn't
have the total attribute values in the VirtualHost.VirtualHostManager.test
bean.
It's working good now.
Thanks,
Matteo

Hello Alex,
managed to connect via jconsole to verify the Attribute values for
VirtualHost.VirtualHostManager.test (had some firewall issues on the return
ports)
Problem I have now is that all those attributes are 0, although I can see
traffic on the queue.
Thanks,
Matteo

Hi Mat,
Could you please clarify what do you mean under "messages handled by
all the queues at any given time"?
Is it the total number of messages received by the queues, or the
total number of messages hold by the queues or messages
receive/delivery rates?
If any of the above, the easiest way to get such information is to
use broker JMX API.
For example, you can get the value of total number of messages
received on virtual host by looking into attribute
"TotalMessagesReceived" on virtual host MBean.
Here is the sample JMX code, retrieving the value of
"TotalMessagesReceived" for virtual host "test" :
public static void main(String[] args) throws Exception
{
Map<String, Object> environment = new HashMap<String, Object>();
environment.put(JMXConnector.CREDENTIALS, new String[] {"admin","admin"});
JMXServiceURL url = new
JMXServiceURL("service:jmx:rmi:///jndi/rmi://localhost:8999/jmxrmi");
JMXConnector jmxConnector = JMXConnectorFactory.connect(url, environment);
MBeanServerConnection mbsc = jmxConnector.getMBeanServerConnection();
ObjectName virtualHost = new
ObjectName("org.apache.qpid:type=VirtualHost.VirtualHostManager,VirtualHost=\"test\"");
Long totalNumberOfMessagesOnVirtualHost =
(Long)mbsc.getAttribute(virtualHost, "TotalMessagesReceived");
System.out.println("Number of messages:" +
totalNumberOfMessagesOnVirtualHost);
}
Kind Regards,
Alex
