This section describes attributes that provide access to other MBeans.


    EnabledServers

    The list of target servers for trap generation. If no server is specified, no trap will be generated.

    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.

    Modulus

    An integer value to be subtracted from the threshold value when the threshold value is crossed.

    If Modulus is 0, a notification is generated each time the agent polls the monitored attribute and its value still exceeds or equals the threshold value.

    If Modulus is larger than 0, the value of the modulus is subtracted from the threshold each time the threshold is crossed.

           
    Privileges Read/Write
    Typeint
    Minimum value0

    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 Sever 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.

           
    Privileges Read/Write
    Typejava.lang.String

    ObjectName

    Returns the ObjectName under which this MBean is registered in the MBean server.

    Deprecated.

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

    Offset

    An integer value to be added to the threshold value each time the observed value equals or exceeds the threshold.

    Privileges Read/Write
    Typeint
    Minimum value0

    Parent

    Return the immediate parent for this MBean

    PollingInterval

    The frequency (in seconds) that WebLogic Server checks the attribute value.

           
    Privileges Read/Write
    Typeint
    Default Value10
    Minimum value1
    Maximum value65535

    Registered

    Returns false if the the MBean represented by this object has been unregistered.

    Deprecated.

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

    Threshold

    Specifies a value that triggers the Counter Monitor to generate a notification.

    The monitor generates a notification the first time the observed value transitions from below the threshold to at or above the threshold. While the observed value remains at or above the threshold, the Counter Monitor does not generate additional notifications. If the observed value falls below the threshold and then later equals or exceeds the threshold, the Counter Monitor does not generate an additional notification.

    You can specify an offset value to cause this threshold value to increase each time the observed value equals or exceeds the threshold. The first time the observed value equals or exceeds the new threshold value, this monitor generates a notification and adds the offset value to the new threshold value.

    For example, if you set Threshold to 1000 and Offset to 2000, when the observed attribute equals or exceeds 1000, the Counter Monitor sends a notification and increases the threshold to 3000. When the observed attribute equals or exceeds 3000, the Counter Monitor sends a notification and increases the threshold again to 5000.

    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
