This section describes attributes that provide access to other MBeans.


    EnabledServers

    This attribute is applicable only when the SNMP Agent is running on the Admin Server of a WebLogic Domain. The EnabledServers attribute allows the users to limit the scope of the monitored data sources to the specific named Servers. The EnabledServers list is ignored when the SNMAgentDeploymentMBean is targeted to a Managed Server. In the case of a Managed Server the SNMP Agent only looks at the data available in the WebLogic Server where the SNMP Agent is deployed.

    For traps based on MBean attributes the SNMP Agent refers to the Domain Runtime MBean Server when it is running on the Admin Server and the Runtime MBean Server when it is deployed to a Managed Server.

    In the case of SNMPJMXMonitorMBean and SNMPAttributeChangeMBean the MonitoredMBeanType and MonitoredMBeanName attributes specify the type and name of a WebLogic Server MBean for which the trap will be setup. MBeans that meet the Type and Name criteria are qualified to set the trap on. The EnabledServers attribute allows a user to specify additional criteria based on the Location of an MBean when the SNMP Agent is targeted to the Admin Server. MBeans whose Location matches one of the Servers in the EnabledServers list are considered eligible for the trap to be generated for a corresponding JMX notification. When the EnabledServers attribute is not specified all MBeans whose Type and Name match are considered as valid sources for the SNMP trap.

    In the case of SNMPLogFilterMBean the EnabledServers attribute allows a user to specify the Servers in the Domain whose log messages will be monitored when the Agent is running on the Admin Server. When EnabledServers is not specified for an Agent running on the Admin Server log messages on all Managed Servers in the domain are monitored for sending traps. This attribute is not applicable when the SNMP Agent is targeted to a Managed Server, in this case the traps are sent based on log messages generated by the respective Managed Server where the Agent is deployed.

    Attributes

    This section describes the following attributes:


    CachingDisabled

    Private property that disables caching in proxies.

           
    Privileges Read only
    Typeboolean
    Redeploy or Restart required Changes take effect after you redeploy the module or restart the server.

    MBeanInfo

    Returns the MBean info for this MBean.

    Deprecated.

           
    Privileges Read only
    Typejavax.management.MBeanInfo
    Redeploy or Restart required Changes take effect after you redeploy the module or restart the server.

    MonitoredAttributeName

    The name of an MBean attribute to monitor. This attribute must be in the WebLogic Server MIB.

           
    Privileges Read/Write
    Typejava.lang.String

    MonitoredMBeanName

    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.

    If you target SNMP agents to individual Managed Servers, make sure that the MBean instance you specify is active on the Managed Servers you have targeted. For example, if you specify MServer1 as the name of a ServerRuntimeMBean instance, this monitor will only function if you target an SNMP agent either to the Administration Server or to a Managed Server named MServer1.

    Do not enter the full JMX object name of the MBean instance. Instead, enter only the value of the object name's Name=name name-value pair. To create unique MBean object names, WebLogic Server encodes several name-value pairs into each object name. One of these pairs is Name=name. For example:
    "MedRec:Name=MedRecServer,
    Type=ServerRuntime"

    In the previous example, specify MedRecServer as the name of the MBean instance.

           
    Privileges Read/Write
    Typejava.lang.String

    MonitoredMBeanType

    The MBean type that defines the attribute you want to monitor. Do not include the MBean suffix. For example, ServerRuntime.

           
    Privileges Read/Write
    Typejava.lang.String

    Name

    The user-specified name of this MBean instance.

    This name is included as one of the key properties in the MBean's javax.management.ObjectName:
    Name=user-specified-name

           
    Privileges Read/Write
    Typejava.lang.String

    Notes

    Optional information that you can include to describe this configuration.

    WebLogic Server saves this note in the domain's configuration file (config.xml) as XML PCDATA. All left angle brackets (<) are converted to the XML entity &lt;. Carriage returns/line feeds are preserved.

    Note:

    If you create or edit a note from the Administration Console, the Administration Console does not preserve carriage returns/line feeds.

    Operations

    This section describes the following operations:


    addEnabledServer

    Adds a feature to the EnabledServer attribute of the SNMPTrapSourceMBean object

       
    Operation Name"addEnabledServer"
    ParametersObject [] {  server }

    where:

    • server is an object of type weblogic.management.configuration.ServerMBean that specifies:

      The feature to be added to the EnabledServer attribute

    SignatureString [] { "weblogic.management.configuration.ServerMBean" }
    Returns boolean
    Exceptions
    • javax.management.InvalidAttributeValueException
    • weblogic.management.configuration.ConfigurationException

    freezeCurrentValue

    If the specified attribute has not been set explicitly, and if the attribute has a default value, this operation forces the MBean to persist the default value.

    Unless you use this operation, the default value is not saved and is subject to change if you update to a newer release of WebLogic Server. Invoking this operation isolates this MBean from the effects of such changes.

    Note:

    To insure that you are freezing the default value, invoke the restoreDefaultValue operation before you invoke this.

    This operation has no effect if you invoke it on an attribute that does not provide a default value or on an attribute for which some other value has been set.

    Deprecated. 9.0.0.0

       
    Operation Name"freezeCurrentValue"
    ParametersObject [] {  attributeName }

    where:

    • attributeName is an object of type java.lang.String that specifies:

      attributeName

    SignatureString [] { "java.lang.String" }
    Returns void
    Exceptions
    • javax.management.AttributeNotFoundException
    • javax.management.MBeanException

    isSet

    Returns true if the specified attribute has been set explicitly in this MBean instance.

       
    Operation Name"isSet"
    ParametersObject [] {  propertyName }

    where:

    • propertyName is an object of type java.lang.String that specifies:

      property to check

    SignatureString [] { "java.lang.String" }
    Returns boolean

    removeEnabledServer

       
    Operation Name"removeEnabledServer"
    ParametersObject [] {  server }

    where:

    • server is an object of type weblogic.management.configuration.ServerMBean that specifies:

      server

    SignatureString [] { "weblogic.management.configuration.ServerMBean" }
    Returns boolean
    Exceptions
    • javax.management.InvalidAttributeValueException
    • weblogic.management.configuration.ConfigurationException

    restoreDefaultValue

    If the specified attribute has a default value, this operation removes any value that has been set explicitly and causes the attribute to use the default value.

    Default values are subject to change if you update to a newer release of WebLogic Server. To prevent the value from changing if you update to a newer release, invoke the freezeCurrentValue operation.

    This operation has no effect if you invoke it on an attribute that does not provide a default value or on an attribute that is already using the default.

    Deprecated. 9.0.0.0

       
    Operation Name"restoreDefaultValue"
    ParametersObject [] {  attributeName }

    where:

    • attributeName is an object of type java.lang.String that specifies:

      attributeName

    SignatureString [] { "java.lang.String" }
    Returns void
    Exceptions
    • javax.management.AttributeNotFoundException

    unSet

    Restore the given property to its default value.

       
    Operation Name"unSet"
    ParametersObject [] {  propertyName }

    where:

    • propertyName is an object of type java.lang.String that specifies:

      property to restore

    SignatureString [] { "java.lang.String" }
    Returns void
