WebLogic Server can use Simple Network Management Protocol (SNMP) to communicate with enterprise-wide management systems. In each WebLogic Server domain the Administration Server hosts an SNMP agent, which gathers management data from WebLogic Server MBeans throughout the domain, converts it to SNMP communication modules (traps), and forwards the traps to SNMP managers.
A managed bean (MBean) is a Java bean that provides a generic management interface based on Java Management Extensions (JMX). All WebLogic resources are instrumented as MBeans and the WebLogic SNMP agent uses their JMX interface to retrieve monitoring data. An SNMP manager is a software component that receives traps. SNMP managers can be packaged within GUI management consoles or can direct their output to scripts or APIs. WebLogic Server includes a simple, Java-based SNMP manager that runs on the command line. See WebLogic SNMP Agent Command-Line Reference.
You can also use the WebLogic SNMP agent to collect SNMP requests from various network resources and forward them to other SNMP agents. See Create SNMP proxies.
You cannot use SNMP to change the configuration of a domain.
For information about loading a MIB, refer to the documentation that the vendors of your SNMP managers supply.
WebLogic
Server installs its MIB as
WL_HOME\server\lib\
BEA-WEBLOGIC-MIB.asn1, where
WL_HOME
is
the directory in which you installed WebLogic
Server.
A trap destination contains the information that the WebLogic SNMP agent needs to send traps to an SNMP manager.
