PRTG Manual: Cluster Status
On the Cluster Status tab, you can view all cluster nodes.
This tab is only available if you run PRTG in a failover cluster.
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.

▪Cluster Log: Shows all log entries for cluster connections
Click the Start Maintenance Mode link to put a cluster node in maintenance mode. A cluster node in this mode is still connected to the cluster, but PRTG discards its monitoring results until you click the Stop Maintenance Mode link. You can use this to explicitly exclude a cluster node from monitoring if you know that the monitoring values are not accurate, for example, because you are reconfiguring the server. During maintenance, PRTG displays a cluster node with a transparent color in the overview graphic.
On the Cluster Status tab, you do not see if your remote probes are connected to failover nodes. Connect to your failover nodes and explicitly check if remote probes are connected, for example, in the device tree of the PRTG web interface on a cluster node.

There are some settings that you must make in the PRTG Administration Tool. For more details, see the sections:
