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.
    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.
