<p>The NodeManager REST API's allow the user to get status on the node and information about applications and containers running on that node. </p></div>

<h3>NodeManager Information API<aname="NodeManager_Information_API"></a></h3>
<p>The node information resource provides overall information about that particular node.</p>
<divclass="section">
<h4>URI<aname="URI"></a></h4>
<p>Both of the following URI's give you the cluster information.</p>
<p>With the Applications API, you can obtain a collection of resources, each of which represents an application. When you run a GET operation on this resource, you obtain a collection of Application Objects. See also <ahref="#Application_API">Application API</a> for syntax of the application object.</p>
<h4>Elements of the <i>apps</i> (Applications) object<aname="Elements_of_the_apps_Applications_object"></a></h4>
<p>When you make a request for the list of applications, the information will be returned as a collection of app objects. See also <ahref="#Application_API">Application API</a> for syntax of the app object.</p>

<p>With the containers API, you can obtain a collection of resources, each of which represents a container. When you run a GET operation on this resource, you obtain a collection of Container Objects. See also <ahref="#Container_API">Container API</a> for syntax of the container object.</p>
