Hi, I have a network of servers and I'd like to get some recomendations for selecting the right tools for this task: - I have a series of simple servers connected on the Internet - I'd like to remotely: - control all those servers, - watch their behaviour, - implement somekind of heartbeat function (servers send heartbeat packets in regular time intervals - if not received -> alarm), - statistics framework for performance analysis - if possible to have secure connections (possibly in software) also for other communication ports that other applications use ... I found some tools like Argus, but as newbie I'm not sure if they satisfy my needs... Any recomendation, idea, pointer to more info would be great, thanks in advance, Robert.
