<%NUMBERING1%>.<%NUMBERING2%>.<%NUMBERING3%> PRTG Manual: Cluster

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?

Node ID

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:

• Active: Set the failover node to active.
• Inactive: Set the failover node to inactive. PRTG disables it in the cluster configuration. The failover node is no longer an active part of the cluster and it does not appear in the cluster status anymore.

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

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.
