Adding instance resourcesΒΆ

As resource needs change, it may become necessary to resize the Plixer Scrutinizer AMI instance and either change its instance type to one that is compatible with the new configuration or migrate the application to a new instance.

To resize the Plixer Scrutinizer instance size and/or make the necessary changes to the instance type, follow these steps:

  1. SSH to the instance and stop all services by entering the following command at the SCRUTINIZER> prompt:

    SCRUTINIZER> services all stop

  2. Power off the operating system by issuing the shutdown -h now command and open the AWS EC2 console.

  3. In the navigation pane, click Instances and select the Plixer Scrutinizer AMI instance.

  4. If the instance has an associated Elastic IP address, take note of it and the instance ID shown in the details pane.

  5. Under Actions,select Instance State and then Stop. Confirm the action and wait for the instance to stop.

Note

Once the instance is stopped, the Elastic IP, Public DNS (IPv4), Private DNS, and Private IPs fields will be blank to indicate that the old values are no longer associated with the instance.

  1. With the instance still selected, choose Actions and then Instance Settings.

  2. Click Change Instance Type and select the desired instance type. If it is not available, the instance type is not compatible with the instance configuration (e.g., because of virtualization type).

  3. When done, select the instance again and choose Actions > Instance State > Start to restart the instance. It may take several minutes for the instance to start up again after confirming the action.

  4. Once the instance is running, confirm that the the Public DNS (IPv4), Private DNS, and Private IPs fields are populated with the new values assigned.

  5. If the instance had an associated Elastic IP address, reassociate it by clicking Elastic IPs in the navigation pane and selecting the Elastic IP address that was previously associated with the instance.

  6. With the correct Elastic IP address selected, click Actions and then Associate Address. After that, select the previous instance ID and click Associate to complete the operation.

Once the instance has been reconfigured, SSH to the instance and issue the set tuning command at the SCRUTINIZER> prompt to retune the appliance.
