title: WSO2 dynamically checking ESB Worker Node in a cluster
body: <p>i m using WSO2 ESBs 4.8.1 configured in a cluster. I'm also using an ELB for loadbalancing all the cluster nodes.</p>
  
  <p>In my project requirements i need to know any time how many esb nodes are attached to the elb, so how many nodes are joining the cluster. Is there the possibility to develop an application able to do that using wso2 api?</p>
  
  <p>Thanks.</p>
