![]() There is no functionality to fill these gaps with the data of other cluster nodes.īecause the monitoring configuration is centrally managed, you can only change it on the primary master node. However, monitoring data for the time of the outage is still available on the other cluster nodes. The data of this single cluster node shows gaps. Because of this, there is no notification flood from all cluster nodes in case of failures.ĭuring the outage of a cluster node, it cannot collect monitoring data. If one or more cluster nodes discover downtime or threshold breaches, only one installation, either the primary master node or the failover master node, sends out notifications, for example, via email, SMS text message, or push message. This cluster node automatically deploys the new version to all other cluster nodes. You only need to install PRTG updates on one cluster node. PRTG also distributes the storage of monitoring results among the cluster. Each cluster node stores the results in its own database. This means that all cluster nodes permanently monitor the network according to the common configuration that they receive from the master node. This ensures continuous data collection.Ī cluster works in active-active mode. If the master node fails, one of the failover nodes takes over and controls the cluster until the master node is back. ![]() The master node automatically distributes the configuration among all other cluster nodes in real time.Īll devices that you create on the cluster probe are monitored by all cluster nodes, so data from different perspectives is available and monitoring continues even if one of the cluster nodes fails. They communicate in both directions and a single cluster node only needs to connect to one other cluster node to integrate itself into the cluster.ĭuring normal operation, you configure devices, sensors, and all other monitoring objects on the master node. Cluster nodes are connected to each other with two TCP/IP connections.
