SNMP Attribute Changes
Column Display Related Tasks Related Topics
Attribute changes configure the SNMP agent to send a trap immediately after a configuration attribute is changed in any way. For example, you can configure an attribute change that sends a trap whenever a server's listen address changes.
To generate traps only when attributes have changed in specific ways (such as the number of connections going beyond a specific threshold), or to generate traps for changes in runtime attributes, create SNMP monitors.
Column Display
You can show fewer or additional data points on this page by expanding Customize this table and modifying the Column Display list. Each data point displays in its own table column.
The following table lists all of the data points that you can display in columns on this page.
Name Description Name The name that you specified when you created the attribute change.
Monitored MBean Type The MBean type that defines the attribute you want to monitor. Do not include the
MBeansuffix. For example,Server.WebLogic Server does not support using Attribute Change trap notifications to monitor run-time attributes. Runtime MBeans always include the word
Runtimein their names. For example, theServerRuntimeMBean provides access to runtime attributes while theServerMBean provides access to configuration attributes. To monitor changes in an MBean that includesRuntimein its name, use a String Monitor, Gauge Monitor, or Counter Monitor.MBean Attribute:
SNMPAttributeChangeMBean.AttributeMBeanTypeChanges take effect after you redeploy the module or restart the server.
Monitored MBean Name The name of the MBean instance that you want to monitor. If you leave the name undefined, WebLogic Server monitors all instances of the MBean type that you specify in Monitored MBean Type.
Do not enter the full JMX object name of the MBean instance. Instead, enter only the value that you provided when you created the instance. To create unique MBean object names, WebLogic Server encodes several name-value pairs into each object name. One of these pairs is
Name=name, and this is the value that you enter for MBean Name. For example:
"MedRec:Name=MedRecServer,
Type=ServerRuntime"In the previous example, specify
MedRecServeras the name of the MBean instance.MBean Attribute:
SNMPAttributeChangeMBean.AttributeMBeanNameChanges take effect after you redeploy the module or restart the server.
Monitored Attribute Name The name of the attribute that you want to monitor. This attribute must be in the WebLogic Server MIB.
MBean Attribute:
SNMPAttributeChangeMBean.AttributeNameChanges take effect after you redeploy the module or restart the server.
