Nagios Support Forum

Hi,
please, can somebody suggest to me a Nagios server configuration to manage and monitor about 50 clients?
Thanks

Are you looking for a hardware configuration, or a basic monitoring configuration for the 50 hosts?

For a Core install, you can probably monitor up to a few thousand hosts on a single core machine. This varies based on what you're monitoring, and if you're doing performance graphing, etc.
