## AI overview

This article explains how Netdata uses parent and child nodes to replicate monitoring data, improve availability, and preserve visibility when a monitored node goes down. It also recommends an active-active parent setup and limiting public exposure to parent nodes.

## Source excerpt

High availability. This is what every monitoring tool needs to ensure that you never compromise on IT infrastructure visibility. On top of high availability, do you really want to enable all available features on your production system? It is important for the monitoring tool to have a low footprint on your CPU consumption and memory usage. Let's dive deeper into the recommended way of configuring Netdata to ensure high availability and a low resource footprint through data replication.
