  2. Execute this script file.
    1
    bash  get_kae_queue_info.sh

    The following information is displayed:

    Engine file, engine queue name, algorithms supported by the engine, total number of queues, and number of remaining queues

    • If the KAE is properly installed and the license is obtained, the information shown in Figure 1 is displayed.
      Figure 1 Command output when the KAE and license are properly installed
    • If the KAE is properly installed but the license is not installed, the information shown in Figure 2 is displayed.
      Figure 2 Command output when the KAE is installed but the license is not installed
    • If the KAE is not installed, the result shown in Figure 3 is displayed.
      Figure 3 Command output when the KAE is not installed
    • If the KAE queues are being used, the information shown in Figure 4 is displayed.

    • You can run the following command to obtain the queue information in real time. Figure 5 shows the command output.
      1
      watch –n 1 bash get_kae_queue_info.sh
      This command indicates that information is displayed every second.
