Additional Operations from the Manage Telegraf Agents Page

After you have configured cloud proxy and installed a product-managed Telegraf agent, configure a vCenter Server Cloud account (relevant only to VMs managed by the vCenter Server cloud account). You can manage the agents on all the target machines from the Manage Telegraf Agents page.

From the Manage Telegraf Agents page, you can:

• Use the filter to easily find physical servers or VMs managed or unmanaged by the vCenter Server cloud accounts.
• View data collected on all target machines.
• Start, stop, and update agents on all target machines where the product-managed agent is installed. You can also discover and manage the services on each product-managed Telegraf agent that you install.
  Note: The maximum allowed application services count per target machine is 200.

Additionally, all the types of supported monitored object types such as Virtual Machine and Endpoint are consolidated in the Manage Telegraf Agents page so that you have visibility of the entire environment you are monitoring and can manage agents and monitor the content from one single page, depending on the agent you are using and type of the objects available. For more information about object types, see OS and Application Monitoring.

Telegraf Agents in VMware Aria Operations

For more information about Telegraf agents, see What Are The Different Types of Telegraf Agents in VMware Aria Operations?.

Note: Data collected from product-managed agents, open-source agents, and user-managed agents can be viewed from the Manage Telegraf Agents page. For objects that have open-source agents and user-managed Telegraf agents installed and running, you can only view data that is collected, you cannot install, uninstall, or manage the lifecycle of the agents.

Where You Manage the Agents

To manage the agents and application services, from the left menu, click Environment > Applications. From the Applications panel, click the Manage Telegraf Agents tab.

Note: In the table below, Vertical Ellipsis is applicable to single VM operations and Agent Actions is applicable to group actions.

Agent Actions > Activate Services	Allows you to activate a service. Note: You can only activate a service for objects with a product- managed Telegraf agent installed and running. Note: Applicable for bulk actions.
Filter	Filters the VMs managed and unmanaged by the vCenter Server cloud account and physical servers based on the name of the VM or the host name in the case of Endpoint type objects, the operating system it runs on, object type, agent type, agent status, the application service discovered, the last operation status, the power status of the VMs managed by the vCenter Server cloud account, and the agent version.

You can also view specific details from the options in the data grid.

To manage the agent, follow these steps:

1. Install the agent.
   For more information, see Install an Agent from the UI.

   Note:

   • You can install the agent from the UI only for VMs managed by the vCenter Server cloud account.
   • To install agents on physical servers and VMs unmanaged by the vCenter Server cloud account, use the script. For more information to install product-managed Telegraf agents, see Install/Uninstall an Agent Using a Script on Linux Platformsand Install/Uninstall an Agent Using a Script on a Windows Platform. For information to install open-source agents, see Monitoring Applications using Open Source Telegraf on a Linux Platform and Monitoring Applications using Open Source Telegraf on a Windows Platform.
2. Manage the application services on each agent.
   For more information, see Activate an Application Service.

   Note: You can manage application services only for objects with a product-managed Telegraf agent installed and running.

   For custom monitoring actions, see Custom Script, Activate Remote Checks, Monitor Windows Services, and Monitor Linux Processes.

3. Stop and start the agents on the target machines.
   When you stop an agent, you cannot activate or deactivate a plugin. If the target machine is powered off or if you lose connection with cloud proxy, you cannot configure or activate a plugin.

   Note: You can stop and start agents only for objects with a product-managed Telegraf agent installed and running.
4. Uninstall the agent.
   For more information, see Uninstall an Agent.

   Note: You can uninstall the agent from the UI only for managed vCenter Server VMs.
5. Update agents that are at a lower version.
