We tried out spiceworks only to find out it doesn't even do any proper monitoring unless we use Nagios with it. So rather than use both, why not just use Nagios?
Before using Nagios though we'd like to know if it is able to monitor multiple sites, and distinguish the sites from each other.
Let's say there's "office - europe", "office - asia" and "office - canada". Canada is the main office and we want to monitor all the IT stuff from one location. Will Nagios be able to do this?
Do we need to have just one nagios installation and agents at all the machines of each locations, or do we need nagios at each location + agents on each device? Will doing this just generate a huge mess of data or can it all be organized by what site it comes from?
