Cloud Connector Extension for OpenStack

Use Case


Elastically grow/shrink instances into cloud/virtualized environments. There are four use cases for the connector.


First, if the Controller detects that the load on the machine instances hosting an application is too high, the cloud-connector-extension-for-openstack may be used to automate creation of new virtual machines to host that application. The end goal is to reduce the load across the application by horizontally scaling up application machine instances.


Second, if the Controller detects that the load on the machine instances hosting an application is below some minimum threshold, the cloud-connector-extension-for-openstack may be used to terminate virtual machines running that application. The end goal is to save power/usage costs without sacrificing application performance by horizontally scaling down application machine instances.


Third, if the Controller detects that a machine instance has terminated unexpectedly when the connector refreshes an application machine state, the cloud-connector-extension-for-openstack may be used to create a replacement virtual machine to replace the terminated application machine instance. This is known as our failover feature.


Lastly, the cloud-connector-extension-for-openstack may be used to stage migration of an application from a physical to virtual infrastructure. Or the cloud-connector-extension-for-openstack may be used to add additional virtual capacity to an application to augment a preexisting physical infrastructure hosting the application.


The Cloud Connector Extension for OpenStack is actually a meta-connector and supports the following OpenStack cloud implementations:

  1. OpenStack Compute (Nova)
  2. Rackspace OpenStack Public Cloud
  3. Rackspace OpenStack Private Cloud
  4. HP Cloud



  1. Download and unzip the cloud-connector-extension-for-openstack zip file into the <controller install dir>/lib/connectors directory.
  2. Restart the Controller and then log into AppDynamics.
  3. In the upper right corner of the window, click Setup -> My Preferences. In the Advanced Features section, enable Show Cloud Auto-Scaling features if it is not enabled.
  4. In the left navigation pane, click Cloud Auto-Scaling to configure the compute cloud and the image.
    • Click Compute Clouds -> Register Compute Cloud. Fill in the required information (shown in the images below) and then click Register Compute Cloud to save the information.
















Select an Image and click 'Launch Instance'





    • Fill the details and click on 'Launch Instance' button.


      • Metadata; specify metadata to be passed. ex: Key1=Value1;Key2=Value2
      • Personality Path: Personality file path. ex: /etc/
      • Personality File: Base64 encoded file content.
