From the virtual machine page in the Azure portal, you can view the installed extension by following these steps:

1. Under Settings, select Extensions + applications.

2. In the Extensions tab, you can see all installed extensions on the virtual machine. If the list is long, you can use the search box to filter the list.

   

Use Get-AzVMExtension cmdlet to list all installed extensions on the virtual machine:

# List the installed extensions on the virtual machine.
Get-AzVMExtension -ResourceGroupName 'myResourceGroup' -VMName 'myVM' | format-table Name, Publisher, ExtensionType, AutoUpgradeMinorVersion, EnableAutomaticUpgrade

The output of the cmdlet lists the installed extensions:

Name                         Publisher                      ExtensionType            AutoUpgradeMinorVersion EnableAutomaticUpgrade

Use az vm extension list command to list all installed extensions on the virtual machine:

# List the installed extensions on the virtual machine.
az vm extension list --resource-group 'myResourceGroup' --vm-name 'myVM' --out table

The output of the command lists the installed extensions:

4. Select Review + create and then select Create.

Use Set-AzVMExtension cmdlet to install Network Watcher Agent VM extension on the virtual machine:

# Install Network Watcher Agent for Linux on the virtual machine.
Set-AzVMExtension -Name 'AzureNetworkWatcherExtension' -Publisher 'Microsoft.Azure.NetworkWatcher' -ExtensionType 'NetworkWatcherAgentLinux' -EnableAutomaticUpgrade 1 -TypeHandlerVersion '1.4' -ResourceGroupName 'myResourceGroup' -VMName 'myVM' 

Once the installation is successfully completed, you see the following output:

Use az vm extension set command to install Network Watcher Agent VM extension on the virtual machine:

# Install Network Watcher Agent for Windows on the virtual machine.
az vm extension set --name 'NetworkWatcherAgentLinux' --extension-instance-name 'AzureNetworkWatcherExtension' --publisher 'Microsoft.Azure.NetworkWatcher' --enable-auto-upgrade 'true' --version '1.4' --resource-group 'myResourceGroup' --vm-name 'myVM'

Use the following Azure Resource Manager template (ARM template) to install Network Watcher Agent VM extension on a Linux virtual machine:

{
    "$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#",
    "contentVersion": "1.0.0.0",
    "parameters": {
        "vmName": {
                "type": "string"
            }
    },
    "variables": {},
    "resources": [
        {
                "name": "[parameters('vmName')]",
                "type": "Microsoft.Compute/virtualMachines",
                "apiVersion": "2023-03-01",
                "location": "[resourceGroup().location]",
                "properties": {
                }
            },
            {
                "name": "[concat(parameters('vmName'), '/AzureNetworkWatcherExtension')]",
                "type": "Microsoft.Compute/virtualMachines/extensions",
                "apiVersion": "2023-03-01",
                "location": "[resourceGroup().location]",
                "dependsOn": [
                    "[concat('Microsoft.Compute/virtualMachines/', parameters('vmName'))]"
                ],
                "properties": {
                    "autoUpgradeMinorVersion": true,
                    "publisher": "Microsoft.Azure.NetworkWatcher",
                    "type": "NetworkWatcherAgentLinux",
                    "typeHandlerVersion": "1.4"
                }
            }
    ],
    "outputs": {}
}

You can use either Azure PowerShell or Azure CLI to deploy the Resource Manager template:

# Deploy the JSON template file using Azure PowerShell.
New-AzResourceGroupDeployment -ResourceGroupName 'myResourceGroup' -TemplateFile 'agent.json'

# Deploy the JSON template file using the Azure CLI.
az deployment group create --resource-group 'myResourceGroup' --template-file 'agent.json'

From the virtual machine page in the Azure portal, you can uninstall the Network Watcher Agent VM extension by following these steps:

1. Under Settings, select Extensions + applications.

2. Select AzureNetworkWatcherExtension from the list of extensions, and then select Uninstall.

   

   Note

   You might see Network Watcher Agent VM extension named differently than AzureNetworkWatcherExtension.

Use Remove-AzVMExtension cmdlet to remove Network Watcher Agent VM extension from the virtual machine:

# Uninstall Network Watcher Agent VM extension.
Remove-AzureVMExtension -Name 'AzureNetworkWatcherExtension' -ResourceGroupName 'myResourceGroup' -VMName 'myVM'

Use az vm extension delete command to remove Network Watcher Agent VM extension from the virtual machine:

# Uninstall Network Watcher Agent VM extension.
az vm extension delete --name 'AzureNetworkWatcherExtension' --resource-group 'myResourceGroup' --vm-name 'myVM'
