Configure maintenance mode during upgrades

Maintenance mode allows new or updated software to run by automatically allowing the incoming software changes in the computer ruleset, while continuing to block any software that has a block rule. Generally, use the following steps to configure maintenance mode:

Procedure

Create a Computer object.
Create and configure an ApplicationControlComputerExtension object to turn on maintenance mode. Optionally, set a duration to turn off maintenance mode automatically. Add the ApplicationControlComputerExtension object to the Computer object.
Use a ComputerApi object to turn on maintenance mode on the computer.
Use the ComputerApi object to verify maintenance mode is on.
If you did not set maintenance mode to turn off automatically:
1. Create a Computer object.
2. Create and configure an ApplicationControlComputerExtension object to turn off maintenance mode and add it to the Computer object.
3. Use a ComputerApi object to turn off maintenance mode.
  
  For more information about maintenance mode, see the Turn on maintenance mode when making planned changes.

What to do next

The following example enables maintenance mode for 10 minutes during a scheduled upgrade:

source

# Create and configure an ApplicationControlComputerExtesnion object
application_control = api.ApplicationControlComputerExtension()
application_control.maintenance_mode_status = "on"
application_control.maintenance_mode_duration = duration

# Add the ApplicationControlComputerExtension to a Computer object
computer = api.Computer()
computer.application_control = application_control

# Update the computer
computers_api = api.ComputersApi(api.ApiClient(configuration))
return computers_api.modify_computer(computer_id, computer, api_version)
