Attribute Label | Description | Value Constraints
--- | --- | ---
Name | The name of this attribute change monitor. Each monitor within a domain must have a unique name. The name displays in the Administration Console, and if you use WebLogic Server command-line utilities or APIs, you use this name to identify the attribute change monitor. After you have created a attribute change monitor, you cannot change its name. Instead, clone the monitor and provide a new name for the clone. For more information, refer to Cloning Configuration Objects. MBean: `weblogic.management. configuration. SNMPAttributeChangeMBean` Attribute: `Name` |
Attribute MBean Type | The MBean type that defines the attribute you want to monitor. For more information, refer to Determining the Names of Other Attributes. MBean: `weblogic.management. configuration. SNMPAttributeChangeMBean` Attribute: `AttributeMBeanType` |
Attribute MBean Name | The name of the MBean instance that you want to monitor. If you leave this field empty, WebLogic Server monitors all instances of the MBean type that you specify in Monitored MBean Type. For more information, refer to Determining the Names of Other Attributes. MBean: `weblogic.management. configuration. SNMPGaugeMonitorMBean` Attribute: `MonitoredMBeanName` |
Attribute Name | The name of the MBean instance that contains the attribute you want to monitor. For more information, refer to Determining the Names of Other Attributes. MBean: `weblogic.management. configuration. SNMPAttributeChangeMBean` Attribute: `AttributeName` |
Enabled Servers | Defines a list of target servers for trap generation. If no server is specified, no trap will be generated. When you assign an Attribute Change monitor to a server, you deploy a JMX listener and filter to the server. The listener will forward a notification to the WebLogic SNMP agent only if an event matches the criteria in the Attribute Change monitor. For example, if you create a Attribute Change monitor that observes the `State` attribute of ServerA's `ServerRuntime` MBean, and if you target this monitor to ServerB, the monitor on ServerB will never generate a trap, because ServerB does not have access to the state of ServerA. MBean: `weblogic.management. configuration. SNMPCounterMonitorMBean` Attribute: `EnabledServers` |
