SNMP Log Filters: Servers

This page lists all servers that have been configured in the domain. If you use an SNMP agent on the Administration Server to listen for log messages from all servers in the domain, then you must select the servers on which you want to activate this log filter.

If you use SNMP agents on individual Managed Servers, you do not need to select a server from this list. An SNMP agent on a Managed Server listens for messages only from its host Managed Server. It ignores this list of servers.

Name Description

Name	Description
Enabled Servers	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. MBean Attribute: `SNMPLogFilterMBean.EnabledServers`

Enabled Servers

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.
