SNMP Agents: Configuration: Log Filters

Column Display     Related Tasks     Related Topics

A log filter enables a WebLogic Server SNMP agent to generate notifications when subsystems or applications generate log messages.

Subsystems and deployable modules (such as applications) on a WebLogic Server instance generate log messages to communicate status or other operational data. The data within a log message is divided into fields that you can use for filtering purposes. For example, each message contains a severity field that indicates the potential impact of the event that generated the message.

Each server saves these messages in a local log file and then broadcasts them as JMX notifications. You can create SNMP log filters that cause a WebLogic Server SNMP agent to listen for these messages. When the agent receives a message that matches the filtering criteria, it generates a notification and sends the notification to the configured trap destinations.

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

The name that you specified when you created the log filter.

Severity Level

The minimum severity of a message that causes a WebLogic Server SNMP agent to generate a notification.

MBean Attribute:

Subsystem Names

A list of subsystems whose messages are selected by this log filter. If none are specified, messages from all subsystems are selected.

MBean Attribute:

User IDs

A list of user IDs that causes a WebLogic Server SNMP agent to generate a notification.

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 notification.

If this log filter doesn't specify user IDs, WebLogic Server can generate a notification for messages from all user IDs.

MBean Attribute:

Message IDs

A list of message IDs or ID ranges that cause a WebLogic Server SNMP agent to generate a notification.

If no IDs are specified, this filter selects all message IDs.

Example list: 20,50-100,300

MBean Attribute:

Message Substring

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 Attribute:

Enabled Servers

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