I would like to know your expert opinion about the best free program for generating and aggregating alarms in a distributed system running on Linux/Unix.
I'm considerably familiar with Nagios but I don't have any experience with others tools. Regarding Nagios I can say that:
1) if I want to get fancy, I can dig into Nagios for myself and come up with a solution.
2) it tends to integrate well with almost anything.
thanks.
