I was wondering if you could help me in choosing and testing a distributed monitoring system for a small hosting company.
I have worked before with Nagios/Centreon and have great experience with them.
The idea is to have two servers, on inside the Data centar, and on outside, connecting the hosts via the NRPE.
I do not want a double alerting system, I just want to avoid a single point of failure.
If one monitoring server goes down, the other one picks it up.
