This chapter describes the tasks you can perform to monitor machines in Fusion Middleware Control 12.1.3. A machine is the logical representation of the computer that hosts one or more WebLogic Server instances. Each Managed Server must be assigned to a machine. The Administration Server uses the machine definition in conjunction with Node Manager to start remote servers.
Node Manager is program that is used to control WebLogic Server instances. A single Node Manager instance is used to control all of the server instances running on the same physical machine. These instances can reside in different clusters, domains, and such. You must configure each machine in your domain to communicate with Node Manager.
For more information on Node Manager, see the Administering Node Manager for Oracle WebLogic Server.
This chapter includes the following sections:
To monitor the machines configured in the current domain:
From the WebLogic Domain dropdown menu, select Environment, then select Machines.
The Machines table displays information about the machines that have been configured in the current WebLogic Server domain, such as:
Name
Type
For more information about these fields, see Configuration Options.
This section describes how to monitor Node Manager. This section includes the following tasks:
To monitor Node Manager status:
From the WebLogic Domain dropdown menu, select Environment, then select Machines.
The Machines table displays information about the machines that have been configured in the current WebLogic Server domain.
For more information, see Configuration Options.
Optionally, select View to access the following table options:
Columns: add or remove the columns displayed in the table
Detach: detach the table (viewing option)
Sort: sort the columns in ascending or descending order
Reorder: change the order of the columns displayed
Query by Example
In the table, select the name of the machine for which you want to view the Node Manager status.
Select the Monitoring page, then select the Node Manager Status page.
If Node Manager is currently running on the machine, the Node Manager Status page displays the following information about the Node Manager process:
Status: current status of this Node Manager
Version: version string returned from the Node Manager
For more information about these fields, see Configuration Options.
Before you begin:
Node Manager must be running to view its logs.
