Working with Controller Logs 

Use

Controller logs display the status history of the operations executed in the adaptive computing landscape. They help in monitoring the operations executed by the adaptive computing controller.

When working with controller logs, you can perform the following activities:

●      Display current or archived controller logs

Controller logs give information about the operations executed using ACC. The controller logs are displayed on the Controller Log screen that consists of the following two sections:

¡        Log overview – To display basic information of an operation such as the operation ID, date, status, application service, and so on.

¡        Log detail – To display information about an operation in terms of the messages generated at the different stages of execution of an operation.

●      Archive current controller logs

To reduce the load of the log database, you can archive and delete the current controller logs.

Archiving, copies log entries from the log database to an external XML archiving storage. You need to delete the log entries from the log database to reduce the load.

●      Delete controller logs

To reduce the load of the log database, when there are too many entries of the controller logs in the log database, you can delete the controller logs.

We recommended that you archive the log entries before deleting them from the log database

You can only retrieve archived log entries, and not the deleted log entries.

●      Export log data into an XML file

To mail or print the log information you can export log data into an XML, and use tools such as Microsoft Office Excel.

Prerequisites

In the Adaptive Computing Controller, choose Logsfrom the navigation panel.
