Hi all! Last month a friend of mine and I started a project at our university (TU Munich) involving your nice little software. This should be our last certificate, so we can finally begin our final exams.
The task, in short, is the implementation of real-time-monitoring, i.e. a timeframe of about 30 minutes to 3 hours overall. gmond should collect the data every 1 or 2 seconds, so state changes can be immediately recognized and be dealt with. So far, we have been studying the code and the rrdtool, and hopefully understood how this things work. Before we play around with the variables, I'd like to ask your opinion: 1. can this be accomplished? My concern is that the overhead gets too much, and ganglia slows the whole cluster down (there must be a reason why the step variable of the gmetad is 15 seconds as default.) 2. is it sufficient to lower the „collect_every“ and „time_threshold“ variables in gmond.conf to speed up the data collection or isn't it that simple? I want the the gmond write its output to the console to see what the collector does. So I change a value, stop and restart with „gmond -d9 start“ but then get: [...] tcp_listen() on xml_port failed: Address already in use How do I get the output without restarting the computer? (when I start gmond for the first time it works). I think I tried to restart gmetad, too, but problem remains. Your help is greatly appreciated, thanks, Tom and Percy -- Ist Ihr Browser Vista-kompatibel?
