[Bamboo Knowledge Base]
If you would like to stop an elastic agent, you can disable it in Bamboo. This will abandon any job build it is running and prevent it from running any further job builds.
Please note, disabling an elastic agent will not shut down the elastic instance it is running on (i.e. you will still be charged for the instance uptime). You can permanently stop an elastic agent and instance by shutting down the elastic instance.
The Bamboo server also "supervises" your elastic agents. If the Bamboo server detects that an elastic agent is offline, it will automatically terminate the elastic instance.
