1. A system to synthesize custom metric attributes from a set of metric attributes associated with an application comprising: a managed server instance in a domain, wherein the managed server instance includes a simple network management protocol (SNMP) Agent, an application having a sub-agent associated therewith, and a managed bean that exposes a set of metric attributes associated with the application, wherein the sub-agent is registered to the SNMP agent, and wherein the sub-agent receives the set of metric attributes associated with the application from the managed bean: an administration server in the domain, wherein the administration server includes a SNMP manager that communicates with the SNMP agent on the managed server instance to receive the set of metric attributes; a network management console having a view panel, wherein the view panel is capable of displaying for selection the set of metric attributes and a plurality of intrinsic attributes, wherein the set of metric attributes are used together with the plurality of intrinsic attributes to build a custom metric attribute, and wherein upon receiving, at the SNMP manager, the set of metric attributes from the SNMP Agent at the managed server instance, the view panel is used to build the custom metric attribute by selecting one or more of the set of metric attributes and one or more of the plurality of intrinsic attributes, and combining the selected one or more of the set of metric attributes with the one or more of the plurality of intrinsic attributes; and wherein the custom metric attribute is then available to one or more other managed server instances in the domain.
