Attribute Label | Description | Value Constraints
--- | --- | ---
Name | The name of this log filter. Each log filter 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 log filter. After you have created a log filter, you cannot change its name. Instead, clone the filter and provide a new name for the clone. For more information, refer to Cloning Configuration Objects. MBean: weblogic.management. configuration. SNMPLogFilterMBean Attribute: Name |
Severity Level | The minimum severity of a message that causes WebLogic Server to generate a trap. The ascending order of severities: `INFO`. Used for reporting normal operations. `WARNING`. A suspicious operation or configuration has occurred but it may not have an impact on normal operation. `ERROR`. A user error has occurred. The system or application is able to handle the error with no interruption, and limited degradation, of service. `NOTICE`. A warning message. A suspicious operation or configuration has occurred which may not affect the normal operation of the server. `CRITICAL`. A system or service error has occurred. The system is able to recover but there might be a momentary loss, or permanent degradation, of service. `ALERT`. A particular service is in an unusable state while other parts of the system continue to function. Automatic recovery is not possible; the immediate attention of the administrator is needed to resolve the problem. `EMERGENCY`. The server is in an unusable state. This severity indicates a severe system failure or panic. If you enter `INFO`, then WebLogic Server can generate a trap when a server instance prints a message of any severity. MBean: weblogic.management. configuration. SNMPLogFilterMBean Attribute: SeverityLevel | Default: WARNING
Subsystem Names | Defines a list of subsystems whose messages are selected by this filter. If none are specified, then WebLogic Server can generate a trap when any subsystem prints a message. MBean: weblogic.management. configuration. SNMPLogFilterMBean Attribute: SubsystemNames |
User Ids | Defines a list of user IDs that causes WebLogic Server to generate a trap. Every message includes the user ID from the security context in which the message was generated. If the user ID field for a message matches one of the user IDs you specify in the filter, WebLogic Server generates a trap. If no IDs are specified, WebLogic Server can generate a trap for messages from all user IDs. MBean: weblogic.management. configuration. SNMPLogFilterMBean Attribute: UserIds |
Message Ids | Defines a list of message IDs or ID ranges that cause WebLogic Server to generate a trap. To see the ID of a message, view a server's message log. For more information, refer to Viewing Server Logs from the Administration Console. If no IDs are specified, this filter selects all message IDs. Example list: 20,50-100,300 MBean: weblogic.management. configuration. SNMPLogFilterMBean Attribute: MessageIds |
Message Substring | Defines a string that is searched for in the message text. Only messages that contain the string are selected. If a string is not specified, all messages are selected. MBean: weblogic.management. configuration. SNMPLogFilterMBean Attribute: MessageSubstring |
Enabled Servers | Defines a list of servers whose messages can cause WebLogic Server to generate a trap. If no server is specified, no traps will be generated. MBean: weblogic.management. configuration. SNMPLogFilterMBean Attribute: EnabledServers |
