Document Scope and Audience
This document is a resource for systems administrators who use SNMP to monitor WebLogic Server.
The topics in this document describe the SNMP capabilities of WebLogic Server. The Administration Console Online Help provides specific, task-related information on configuring SNMP services in a WebLogic Server domain.
It is assumed that the reader is familiar with SNMP and general network management concepts. For background information on SNMP, refer to the documents listed in Related Documentation.
Guide to this Document
This document is organized as follows:
- This chapter, Introduction and Roadmap, describes the audience of the guide and provides pointers to related documentation.
- Understanding the WebLogic SNMP Agent and MIB, describes basic concepts of Simple Network Management Protocol as they apply to managing WebLogic Servers.
- Understanding WebLogic Server Trap Notifications, describes the characteristics of WebLogic enterprise-specific SNMP trap notifications.
- Understanding SNMP Proxies, describes how WebLogic Server can function as a master agent that proxies for other SNMP agents.

Standards and Drafts
The SNMP protocol has been defined through a series of Requests for Comments (RFCs). The standards and drafts in Table 1-1 are available from www.faqs.org/rfcs.
New and Changed SNMP Features in This Release
Release 9.0 does not change or add functionality to the SNMP agent and its monitoring features. However, this release significantly reorganizes the WebLogic Server management data model. Because of this reorganization, the WebLogic Server MIB contains many new managed objects. To access these new managed objects, load the 9.0 WebLogic Server MIB into your management stations.
In addition, many WebLogic Server MBeans are deprecated, which means that the corresponding managed objects in the MIB are deprecated and will be removed in future releases. If you listen for changes or monitor deprecated MBeans, update your attribute change notifications or monitor notifications to use the replacement MBean.
- See Understanding WebLogic Server MBeans in Developing Manageable Applications with JMX.
- To see a list of deprecated MBeans, open the WebLogic Server MBean Reference and look under the Deprecated category in the left pane.
- Some MBeans have been removed without being deprecated because publication of the MBeans in prior releases was erroneous. See JMX Known Issues in WebLogic Server Release Notes.
- "Use SNMP to Monitor WebLogic Server" in the Administration Console Online Help.
