Can't install or uninstall the agent on a virtual machine

This article explains how to resolve problems with installing or uninstalling the New Relic agent on a virtual machine (VM). Specifically, it describes what to do if you select VMs and the Install Extension or Uninstall Extension button is unavailable.

Prerequisites

• An Azure account with permissions to manage VM extensions (Contributor or Owner on the subscription or resource group, or a role with explicit extension management permissions).
• The target VMs must be visible in the Azure portal on the Virtual machines page.

Symptoms

• On the Virtual Machines page of the New Relic resource, the Install Extension button is unavailable (dimmed) after you select one or more VMs.
• On the Virtual Machines page of the New Relic resource, the Uninstall Extension button is unavailable (dimmed) after you select one or more VMs.

Cause

The portal enables the Install Extension or Uninstall Extension button only when the entire selection of VMs matches the required state for that action:

• Install Extension is enabled only when none of the selected VMs has the New Relic agent installed.
• Uninstall Extension is enabled only when every selected VM already has the New Relic agent installed.

The Azure portal displays the agent/extension state in the Agent status column:

• VMs on which the New Relic agent is installed show Running or Shutdown.
• VMs on which the New Relic agent isn't installed show Not Installed.

If your selection includes VMs in different states (some that have the agent and some that don't), neither Install Extension nor Uninstall Extension will be enabled.

Solution

1. In the Azure portal, go to the Virtual Machines page of the New Relic resource.
2. To install the New Relic agent:
   1. Select only VMs that show an Agent status of Not Installed.
   2. Deselect any VMs that show a status of Running or Shutdown. (These VMs already have the agent.)
   3. Confirm that the Install Extension button is active and then proceed.
3. To uninstall the New Relic agent:
   1. Select only VMs that show an Agent status of Running or Shutdown. (These VMs have the agent installed.)
   2. Deselect any VMs that show a status of Not Installed.
   3. Confirm that the Uninstall Extension button is active and then proceed.
