I'm currently looking for tool that support distributed monitoring. By distributed monitoring I mean tool that are able to work on multiple servers and that are able to send the collected data to a central point.
I've already look at different solutions such as Shinken, Sensu, Nagios, and much more.
I would to know now what you are actually using ? How ? Why did you choose it ? and so on.
I'll be glad to get your answers.
