I am a BB user for long time, but due to licencing problems i have to look to another monitoring product. Can someone enlighten me on the main difference between BB en Nagios? Can Nagios e.g. monitor Window clients easily? Are there plugins for windows clients (XP, 2000, 2003 etc)? I would like to use Nagios in a big mixed environment so it’s important that different OS’es are supported. Is this the case with Nagios?
Furthermore is it allowed to use Nagios in a commercial organisation without any costs?
Thanks for your replies!
