public interface SNMPAgentDeploymentMBean
extends SNMPAgentMBean, DeploymentMBean

This MBean is an SNMP agent that can be targeted to instances of WebLogic Server.

With SNMP, you configure agents to gather and send data about managed resources in response to a request from managers. You can also configure agents to issue unsolicited reports to managers when they detect predefined thresholds or conditions on a managed resource.

In a WebLogic Server domain, you can choose a centralized or de-centralized model for SNMP monitoring and communication:

• In a centralized model, you create an instance of this MBean and target it only to the Administration Server. This agent communicates with all Managed Servers in the domain. SNMP managers communicate only with the SNMP agent on the Administration Server. This model is convenient but introduces performance overhead in WebLogic Server. In addition, if the Administration Server is unavailable, you cannot monitor the domain through SNMP.
• In a de-centralized model, you create an instance of this MBean and target it to each Managed Server that you want to monitor. (Alternatively, you can create multiple instances of this MBean and target each instance to an individual Managed Server.) Your SNMP manager must communicate with the agents on individual Managed Servers.

To support domains that were created with WebLogic Server release 9.2 and earlier, a domain also hosts a singleton SNMP agent whose scope is the entire domain (see SNMPAgentMBean). SNMPAgentMBean offers the same features as an instance of this MBean (SNMPAgentDeploymentMBean) that you have targeted as described in the centralized model above. However, the underlying implementation of SNMPAgentMBean is different and it will eventually be deprecated. SNMPAgentMBean is overridden if you target an instance of this MBean to the Administration Server.
