I am new to Nagios and so far I love the capabilities that it has to offer. After reading through the documentation I have not been able to find a clear answer as to if Nagios can gather data from Different sites that are separated by WAN links.
Ideally I would like to be able to gather data from my clients sites about server uptime, process information (SQL Server, Exchange 2000, etc). and send data back to my office for Network Monitoring and analysis.
Any help or suggestions about this would be greatly appreciated.
