Activating or Deactivating Agent Instances
The activate command enables one or more Foglight™ agent instances.
To create an agent instance that collects data, you first create the agent instance, activate it, and then start the data collection for that agent instance. Similarly, when you want to remove an agent instance, use a reverse order of actions: first stop the agent instance, deactivate it, and then delete it.

TIP: Some Foglight agents, such as the AIX® and HP ® system agents that come included with the OS Cartridge, require root-level privileges to run on UNIX ®. This can be accomplished by making sure that the user account used to install the Foglight Agent Manager on the monitored host does not appear in the sudo configuration file. However, if the Agent Manager does not have root-level privileges, the agents that require those privileges fall back to normal, non-root launch. Starting those agents without root privileges does not prevent them from activating and collecting data. For more information about installing the Foglight Agent Manager with root privileges, see the I nstallation and Configuration Guide. For information about the OS Cartridge, refer to the cartridge documentation. |

deactivate
The deactivate command disables one or more Foglight™ agent instances.
If you want to delete an agent instance, you first stop the agent’s data collection, deactivate it, and then delete the instance.
To delete an agent instance, a typical flow of actions requires you to first stop the agent’s data collection, deactivate it, and then delete the instance. However, the deactivate command includes options and arguments, such as -datacollection true, that allow you to override that flow and agent instances that are collecting data.

Starting or Stopping Data Collection
The start command initiates data collection for one or more Foglight™ agent instances.
To create an agent instance that collects data, you first create the agent instance, activate it, and then start the data collection for that agent instance. Similarly, when you want to remove an agent instance, use a reverse order of actions: first stop the agent instance, deactivate it, and then delete it.
You should issue this command after creating and/or activating an agent instance. For information on how to activate agent instances using the fglcmd interface, see activate .
