New Features in PRTG 8 - Part 3: Introducing "The PRTG Cluster"

While the beta test of PRTG 8 is running we are posting a series of blog articles about new features! With version 8, we introduce a completely new and up-to-date feature: PRTG’s failover clustering. It is included in all licenses and enables you to set up a fail-safe monitoring system with seamless data—no more data gaps when a system crashes or when you have to restart your server (not even a software upgrade of PRTG will stop monitoring). I want to give you a little insight into what our clustering does and how to configure it easily.

Simple Failover Cluster

The most common setup is two PRTG servers running “side-by-side” in a single failover cluster. The first node is the Master Node and is responsible for the configuration, management, alerting, and reporting. If this PRTG instance should fail, e.g. due to a server crash or connectivity issues, the second node (i.e. the Failover Node) takes over the master role and continues the monitoring until the original Master Node is back online.
