As an IT Infrastructure Manager, I want to deploy redundant remote probes that automatically replicate sensor configurations and provide seamless failover capabilities, so that I can ensure continuous monitoring coverage without manual intervention during probe outages and eliminate single points of failure in remote locations.

In environments where uptime and monitoring continuity are critical — especially in OT and industrial networks — a single PRTG Remote Probe represents a potential single point of failure. Currently, if a probe goes offline, all sensors assigned to it immediately lose visibility until the probe is restored.

I propose a High Availability (HA) Probe feature, where two probes can be deployed as a redundant pair and configured with an “HA Mode” option.
In this setup:

Primary Probe runs active monitoring and synchronizes its configuration and sensor definitions to the Secondary Probe in real time.

When the Primary Probe becomes unavailable (due to maintenance, network issue, or failure), the Secondary Probe automatically detects the failure and takes over all sensor operations.

Once the Primary Probe returns, synchronization resumes, and historical data merges seamlessly.

This feature would ensure continuous monitoring, no data loss, and no manual reconfiguration during probe outages.

Such a feature would be especially valuable in segmented OT environments following the Purdue Model, remote sites, and distributed enterprise networks where reliability and redundancy are vital. It would also align PRTG with enterprise monitoring standards that already offer agent failover capabilities.
