Configuring the Traffic-Mirroring Application

To use the traffic-mirroring application, you must configure properties to specify how the application handles information about mirroring tasks and the aggregate service that the application activates to mirror traffic.

To configure these properties for the traffic-mirroring application:

1. In SDX Admin go to l=TrafficMirroring, l=WebApplication, ou=staticConfiguration, ou=Configuration, o=Management, o=umc.
2. In the Main tab for Configuration, modify the following properties.

directory

• Specifies the directory in the file system in which information about the mirroring tasks is stored. The application stores all tasks in a series of files that are considered live or dead. Live files record at least one active or pending task and include the word live in their names. Dead files record only tasks that have been canceled or stopped and include the word dead in their names. You can delete or archive dead files at any time. However, if you delete a live file, the application will not be able to access information about existing tasks.
• Value—<pathname>
• Guidelines—The application server must be able to write and modify files in this directory. If you use WEB-INF, you will lose all your data about the mirroring tasks whenever you undeploy or redeploy the traffic-mirroring application.
• Default—WEB-INF

retryInterval

• Time to wait before retrying a pending task that was unsuccessful.
• Value—Number of seconds
• Guidelines—Do not specify too small a value, because the number of service activation attempts could cause network overload.
• Default—900

serviceName

• Name of the aggregate service activated by the application to mirror subscriber traffic.
• Value—<service name>
• Default—MirrorAggregate

maxFileSize

• Maximum file size for files that store information about the pending and active tasks. A new file is created whenever the current file exceeds this setting.
• Value—Number of bytes
• Guidelines—This value should not need modification.
• Default—1000000 (1 MB)
