Are you familiar with Nagios monitoring system? I'd like to have monitoring set up to monitor three Windows servers and some 7 Linux servers. All Windowses are 2012 R2 and Linuxes Ubuntu 14.04.
Most of the servers are running on one main host. That host should also be monitored. So I need two central monitoring servers (one in the same physical host, one in totally different host computer from a different provider).
Documentation should be also included. Same level as with e-mail set up project (iredmail) is fine.
