Deploy VM Monitoring Points

Deploy a VM or KVM Monitoring Point inside your cloud, hybrid, or multi-cloud network to monitor your network or web application performance.

To start monitoring, download the Monitoring Point images from Google Cloud, and then deploy the image using VMware vSphere (vCenter or ESXi) or Linux KVM (QCOW2) by following the instructions from AppNeta.

Before you begin

The deployment environment and Monitoring Points have specific networking requirements to ensure that the Monitoring Point can be installed successfully and communicate back to the Cloud Network Insights control plane.

Required roles

To get the permissions that you need to add Monitoring Points, ask your administrator to grant you the Cloud Network Insights Editor (roles/networkmanagement.CloudNetworkInsightsEditor) IAM role on the project that has Cloud Network Insights enabled. For more information about granting roles, see Manage access to projects, folders, and organizations.

You might also be able to get the required permissions through custom roles or other predefined roles.

Firewall requirements

Since we recommend installing Monitoring Points behind your firewalls, you might need to modify your firewall rules. Monitoring Points require outbound internet access to communicate back to the Cloud Network Insights control plane.

Protocol	Port	Description
TCP	443 (HTTPS)	Required. Connectivity to the Cloud Network Insights control plane
UDP	123 (NTP)	Required. Network Time Protocol. The Monitoring Point will fail to connect if time is not synced
UDP/TCP	53 (DNS)	Required. Domain Name Service to resolve Cloud Network Insights endpoints
UDP	3239, 33434	Test Traffic. Required for standard Network Path monitoring (dual-ended)
ICMP	Type 8 (echo request)	Test Traffic. Required for single-ended paths (for example, pinging 8.8.8.8).

For more information, see Firewall Configuration from AppNeta.

Monitoring Point requirements

Review the AppNeta Monitoring Point specifications to ensure that you can successfully deploy them.

• Specifications – v35-VMware
• Specifications – v35-KVM

Download Monitoring Point image and configuration

You can download a zip file locally with the Monitoring Point images and configuration files or generate a command to download the installation bundle on the machine you're installing the Monitoring Point on.

1. In the Google Cloud console, navigate to Network Intelligence > Cloud Network Insights > Monitoring Points.

   Go to Cloud Network Insights

2. Click Add monitoring point.

3. In the Platform Type list, select either KVM or VMware, and then click Continue.

4. Enter the Password for the VM.

5. Choose your IP Configuration.

   • If the target network assigns IP addresses automatically, select Obtain settings using DHCP.
   • If you want to use a static IP address, select Static IP.

6. Complete the following IP configuration fields. Fields are based on what you selected for the IP Configuration.

   • IP Address: The IPv4 address that you want to assign to the Monitoring Point.
   • Network Mask:The subnet mask (for example, 255.255.255.0).
   • Network Gateway: The default gateway IP address.
   • DNS 1: The IPv4 address of your primary DNS servers (for example, 8.8.8.8).
   • DNS 2 (optional): A backup name server to ensure connectivity if the primary fails (for example, 1.1.1.1)
   • Domain name: The default DNS search domain for the Monitoring Point.
   • Hostname: The unique name for this Monitoring Point.
   • Timezone (optional): The timezone of the VM the Monitoring Point is installed on.
   • NTP 1 (optional): The primary Network Time Protocol address (IP or FQDN).
   • NTP 2 (optional): A backup time server used if the primary address is unreachable.

7. Click Continue.

8. In Download the Monitoring Point, choose how you want to download the installation bundle.

   • To download the installation bundle locally, select Download locally.
     1. Click Download Monitoring Point.
        • For KVM: Download a ZIP file that contains an ISO file (boot/config drive).
        • For VMware: Download a ZIP file that contains a JSON file (deployment parameters).
     2. Download the disk image. The available options depends on your selected Platform Type.
     3. Move the configuration file and the disk image to your hypervisor management station.
   • To generate a command-line command to run on the host, select Run a command on the host.
     1. Click Open shell and generate token. You might need to authorize Cloud Shell.
     2. Press Enter to generate a token, and then copy and paste it in the text field in Generate the command.
     3. Open a terminal to your host using administrator credentials, and run the generated command to download the configuration files.
     4. Download the disk image. The available options depends on your selected Platform Type.
     5. If necessary, move the configuration file and the disk image to your hypervisor management station.

Deploy VM-based Monitoring Point

Once you have the images, follow the instructions from AppNeta to deploy the Monitoring Point.

• VMware

• Linux KVM (QCOW2)

After deploying the VM, record the MAC Address of the primary network adapter (eth0 or Network Adapter 1) from your hypervisor (vCenter or KVM).

• Username: admin
• Default Password: The MAC address in UPPERCASE with no colons (for example, 00505681450A).

You need these credentials if you need to sign in to the Monitoring Point's Web Administration interface to troubleshoot connectivity issues. For more information, see AppNeta's documentation.

Configure a web proxy

If your network requires a proxy for outbound access, you must configure it after the VM is powered on.

• KVM Web Proxy Configuration
• VMWare Web Proxy Configuration

Verify the install

Open the Google Cloud console and navigate to Network Intelligence Center > Cloud Network Insights. After 2–5 minutes, the Monitoring Point appears in the table with the status Active. If it doesn't appear within ten minutes, see Troubleshooting.

Remove Monitoring Points

To remove a Monitoring Point, delete it in AppNeta. For more information about removing a Monitoring Point, see the AppNeta documentation.

What's next

After you add Monitoring Points, it's time to create monitoring policies to populate Cloud Network Insights with data.
