Fusing remote servers is what Nagios Fusion is all about. Fusing a server is the process in which a remote Nagios XI or Core host is added to Nagios Fusion. This allows you to poll those servers for the data that's important to you. When you fuse servers, you gain insight into the health of those remote hosts across your infrastructure quickly.

• Nagios Core 4.0.7 or later
• Nagios Log Server 2.0.1 or later
• Nagios Network Analyzer 2024 or later
