Applicare Blackbox: Creating a Blackbox

The Blackbox enables you to analyze WebLogic server state even after a system failure (crash). When Applicare monitoring is ON for a particular server, Applicare anticipates a potential hung conditions and takes a “snapshot” of the WebLogic server state for analysis later in the event a failure actually occurs.  You can also create a Blackbox at any time to save the state of WebLogic server for later analysis.

 To create a Blackbox:

1. Click on Applicare WL > Applicare Blackbox > Run Blackbox. The Applicare Blackbox Start Screen displays.

2. Select the server from the drop-down menu and click Create Blackbox; Applicare creates the Blackbox for the server selected. When Applicare successfully creates the Blackbox, a message appears asking you to click on the Display Blackbox node.

3. Click on Applicare > Display Blackbox to display the Show Blackbox screen which shows the following:

·         Server: The name of the WebLogic server for which the Blackbox was created.

·         Session: The timestamp indicating when the server, along with Applicare was started, during which the snapshot was taken.

·         Time: The timestamp of the exact time the Blackbox was created.

·         The Server Structure Tree showing categories of the server runtime MBeans.  

4.                  Double click on a category or click on the plus icon.  The MBean nodes, designated by the () icon, are displayed.

5.                  Click on the MBean node you want to analyze.  The Blackbox displays Property and Value data for the MBean at the time the snapshot was taken.
