I want to integrate an existing PRTG version 8 server into a failover cluster with two PRTG version 8 installations.
Can you please instruct me how to do this?

This article applies to PRTG 8.
This article explains how to set up a cluster of two servers (master node and failover node) with PRTG Network Monitor 8.
Important: Before getting started, please make sure you've read the introduction: How do I set up a cluster in PRTG 8?
It contains important hints and preparation steps you should consider before proceeding. Additionally, you will find there links to instructions on how to set up other scenarios.
Your aim: Integrate an existing PRTG version 8 server into a failover cluster with two PRTG version 8 installations. Your existing installation will be the cluster's master node.
| On “Master Node“ server | On “Failover Node“ server |
|---|---|
| On “Master Node“ server with the existing PRTG installation, execute the PRTG Network Monitor Setup program. Follow the installation wizard. This will update your installation to the current version. | — |
| On “Master Node“ server | On “Failover Node“ server |
|---|---|
| From the Start menu, open the PRTG Server Administrator program. In the Cluster tab, change the cluster mode from Standalone to Cluster Mode: Master Node. A Cluster Access Key is automatically generated and does not have to be changed. You can leave the standard setting for Cluster Port. Save both cluster access key and port number in a text file for later use; you will need it in the cluster settings on “Failover Node“ server (step 6). Confirm with OK and select Yes to restart the PRTG core server service. | — |
Time to take a deep breath. Continue with the next step.
| On “Master Node“ server | On “Failover Node“ server |
|---|---|
| — | On “Failover Node“ server, execute the PRTG Network Monitor Setup program. Follow the installation wizard. Enter the essential settings and click on Next. You will eventually see the cluster mode selection (step 4 of 5). |
| On “Master Node“ server | On “Failover Node“ server |
|---|---|
| — | Once you’ve reached the Cluster Mode Selection (Step 4 of 5) on “Failover Node“ server, select Run PRTG in “Cluster Mode” and click on Next. |
| On “Master Node“ server | On “Failover Node“ server |
|---|---|
| — | In the Cluster Settings (Step 5 of 5) on “Failover Node“ server, select Install a Failover Node. Insert the password and port number into the Cluster Access Key and Cluster Port fields. You’ve saved this information before during setup on the “Master Node” server. In the Master field, enter the IP address or DNS name of your “Master Node” server. Finish the installation. |
| On “Master Node“ server | On “Failover Node“ server |
|---|---|
| Now you need to confirm the new failover node by setting it to Active in the master node's settings. In a browser window, log into PRTG’s web interface of the “Master Node” server. Choose Setup (screwdriver symbol) | System Administration | System Setup from the main menu and click on the Cluster Settings tab. You will see your “Master Node” server in the first line of the cluster list and your “Failover Node” server below. For the “Failover Node”, set the radio button for Node State to Active and save the changes. The nodes will now connect and exchange configuration data. This may take a few minutes. | — |
| For “Master Node“ server and for “Failover Node“ server |
|---|
| In two browser windows, log into PRTG’s web interfaces of both of your PRTG installations. Open the cluster status page in both windows by clicking on the narrow cluster information bars at the top of each window. You should see a cluster status with your two nodes in a Connected state after a few minutes. |
Having any problems? If your nodes cannot connect, please see
In the latest entries of these logs, you can see messages about any errors that might have occurred. These will give you hints on where to find a solution.
If you encounter connection problems between the two cluster nodes, please make sure that no software- or hardware firewall is blocking communication on the cluster port defined during cluster setup. Communication between the nodes must be possible in both directions in order for the cluster to work properly.
That’s it. You’ve now successfully set up your failover cluster. All devices that are created or moved under the Cluster Probe will be monitored by all servers in the cluster.
In order to monitor your existing configuration via all cluster nodes, on your master node, please move your groups, devices, and sensors from the local probe to the cluster probe! Objects including their settings will then automatically be transferred to all cluster nodes.
Please repeat Step 4 to Step 9 for each additional failover node you want to set up.
