To start or stop the Controller:

  • Linux users can use the Enterprise Console GUI or CLI.
  • Microsoft Windows users can use the Enterprise Console GUI or following Windows services:
    • AppDynamics Database
    • AppDynamics Controller Application Server
    • AppDynamics Reporting Service

To check the Controller health, Linux and Windows users can use the Enterprise Console GUI or CLI.

Scripts Used to Start or Stop the Controller

The scripts to start and stop the Controller and other Cisco AppDynamics On-Premises platform processes are located in the platform-admin/bin directory for standalone or secondary HA Controllers. Using the platform-admin script, you can start the platform processes individually or all at once. 

To avoid the possibility of data corruption errors, ensure to stop the application server and database gracefully by using the stop scripts before shutting off or rebooting the machine on which the Controller is running.

You can start and stop the Controller and Controller services on the Controller page in the Enterprise Console GUI or from the Enterprise Console command line. When you start and stop the Controller, the services and processes related to the Controller also start and stop, including the Reporting Service. If you use the GUI to start and stop the Controller, specify that you want to stop MySQL if you want to also stop the Controller Database.

If your Enterprise Console manages multiple platforms, to distinguish the Controller platform, you must use the command line for standalone or secondary HA Controllers and specify the --platform-name <name_of_the_platform>.

For example:

platform-admin.sh start-controller-db --platform-name <name_of_the_platform>
platform-admin.sh start-controller-appserver --platform-name <name_of_the_platform> 
CODE

To see all options, run platform-admin.sh list-jobs --service controller --platform-name <platform-name> from the command line. For more information, see Enterprise Console Command Line or Administer the Enterprise Console.

The Enterprise Console has a max wait time of 45 minutes when starting or stopping the Controller. You can set a timeout which exits the command and returns a failure by appending --args controllerProcessTimeoutInMin=<minutes> to the end of your start or stop command.

How to Start or Stop a Standalone Controller

The following commands apply to standalone Controllers. See Starting or Stopping a Controller for information on how to start or stop Controllers in High Availability (HA) pairs.

Start and Stop the Controller App Server

When using the Enterprise Console, starting or stopping the Controller will also start or stop the Reporting Service.

Start the Controller App Server

The start-controller-appserver command starts the database automatically.

platform-admin.sh start-controller-appserver
BASH

On Windows, the Controller processes are installed as a service, named the AppDynamics Controller Application Server service and AppDynamics Database service.

Start the Windows Service > AppDynamics Controller Application Server to start the Controller App server.

The database starts automatically when you start the Controller App server.

Stop the Controller App Server

The stop-controller-appserver command does not stop the database.

platform-admin.sh stop-controller-appserver
BASH

Stop the app server:

Stop the Windows Service > AppDynamics Controller Application Server to stop the Controller app server.

The database does not stop when you stop the Controller app server.


Start and Stop the Controller Reporting Service

Start the Reporting Service

To start the Controller Reporting Service:

You must log in to the Controller host before running the scripts to start the controller.sh processes.

bin/controller.sh start-reporting-service
CODE
Start the Windows Service > AppDynamics Reporting Service to start the Controller Reporting Service.
Stop the Reporting Service

You must log in to the Controller host before running the scripts to start the controller.sh processes.

bin/controller.sh stop-reporting-service
CODE
Stop the Windows Service > AppDynamics Reporting Service to stop the Controller Reporting Service.

Start and Stop the Controller Database

Start the Controller Database

platform-admin.sh start-controller-db
BASH
Start the Windows Service > AppDynamics Database to start the Controller database.

Stop the Controller Database

platform-admin.sh stop-controller-db
BASH
Stop the Windows Service > AppDynamics Database to stop the Controller database.

How to Start or Stop a Controller in High Availability Pairs

Use the following commands to start or stop Controllers in HA pairs:

  • You should disable auto-failover before restarting a primary Controller. Do not forget to reenable auto-failover afterward.
  • If you enabled auto-failover in the Enterprise Console, and you stopped the app server, the Watchdog will trigger a failover if it takes longer than five minutes to update.
  • If you are using a combination of the Enterprise Console with the High Availability Toolkit (HATK), then you can start or stop the Controller using services.

Start and Stop the Controller

Start the Controller

You must log in to the primary Controller host before running the scripts to start the controller.sh processes.  

bin/startController.sh
BASH 
service appdcontroller start
BASH

Stop the Controller

bin/stopController.sh
BASH 
service appdcontroller-db stop
BASH

Start and Stop the Controller App Server

You must log in to the primary Controller host before running the scripts to start the controller.sh processes. 

Start the App Server

bin/controller.sh start-appserver
BASH 
service appdcontroller start
CODE

Stop the App Server

bin/controller.sh stop-appserver
BASH 
service appdcontroller stop
CODE

Start and Stop the Controller Database

You can start and stop the Controller database either on the primary or the secondary host based on which database you require to restart.

Start the Database

To start the database, run this script on the server where you have hosted the database:

bin/controller.sh start-db
CODE 
service appdcontroller-db start
CODE
Stop the Database

To stop the database, run this script on the server where you have hosted the database:

bin/controller.sh stop-db
CODE 
service appdcontroller-db stop
CODE

How to Check Controller Health

To check the Controller health status from:

  • Enterprise Console GUI, navigate to Platform > <name of the platform> > Controller. The right pane displays the health status of the Controller.
    You can check the health status of each node from the Controller table. The Running State column displays the status for the corresponding Host.
  • Enterprise Console server, run:
bin/platform-admin.sh check-controller-health
CODE


The following output shows the status of the Controller and its uptime:

Controller status : HEALTHY; Started 6 seconds ago.
CODE 
bin\platform-admin.exe cli check-controller-health
CODE

The Powershell Execution Policy must be set correctly for the command to work. See https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.core/about/about_execution_policies?view=powershell-7.2.
