PRTG Manual: Cluster
On the Cluster tab, you can change cluster-related settings. See the cluster status to see if all cluster nodes are properly connected.
This documentation refers to an administrator that accesses the PRTG web interface on a master node. Other user accounts, interfaces, or failover nodes might not have all of the options in the way described here. In a cluster, note that failover nodes are read-only by default.
If 15 minutes (900) seconds have passed since your last credential-based login and you open a setup page from a different setup page, PRTG asks you to enter your credentials again for security reasons. A dialog box appears. Enter your Login Name and Password and click OK to continue.
This feature is not available in PRTG Hosted Monitor.

Description |
---|---|
Node Name |
Enter the name of the cluster node. PRTG uses it for display purposes only. If the name contains angle brackets (<>), PRTG replaces them with braces ({}) for security reasons. For more information, see the Knowledge Base: What security features does PRTG include? |
NodeID |
The ID is unique for every cluster node. We recommend that you use the default value. |
Node Status |
Set the state for each failover node:
This setting is not available for the master node of a cluster. The master node is always Active. |
IP Addresses/DNS Names Used for Node-Node Connections |
Define the IP addresses or Domain Name System (DNS) names that PRTG uses for the node-node connections. You can enter different values for every connection. For example, in the field #2 => #1, enter the address under which the master node is reachable from the second cluster node. Usually, this is the IP address or DNS name of the master node. Do this for all available cluster node connections, for example, if you have three cluster nodes, enter the address under which the second cluster node is reachable from the third cluster node in the field #3 => #2. For more information, see the Paessler website: How to set up a failover cluster in PRTG in 6 steps. If you use remote probes outside your local network or outside your network address translation (NAT), make sure that the IP addresses or DNS names that you enter are valid for both the cluster nodes to reach each other and for remote probes to reach all cluster nodes individually. These addresses must not be private and must be reachable from the outside, otherwise the remote probes cannot connect. Multi-platform probes do not support clusters. |
Save your settings. If you change tabs or use the main menu without saving, all changes to the settings are lost.
For more information on how to set a cluster node into Maintenance Mode, see section Cluster Status.
The entire setup process for a cluster requires several different steps. For more information and step-by-step guidance, see the Paessler website: How to set up a failover cluster in PRTG in 6 steps.
