In our company, we have one nagios for each of our clients, to offer them a 24x7 monitoring service. Currently, we are using Coffeesaint to have a "central monitoring display" were all alarms about hosts and services are shown. But it does not work perfectly all the time with more than 3 nagios configured and having to read large "status.dat" files. So we're thinking about changing from Coffeesaint to any other tool that does "the same".
I would like to know if you know any other tool that does the same but is more complete or has more options than Coffeesaint.
