I personally would not worry to much. At least not before measuring the impcat on a life system :-) In any case, if gmetric is to "heavy" for yoo, you could always integrate your metrics into the metrics reported by "gmond". This is not trivial, but not impossible. The drawback is that it may make that "gmond" incompatible with the standard one. Another solution would be to look at the gemetric source and write your own version that collects all interesting metrics and submits them together. That way you would reduce the number of "forks".

Ok, probably not what you wanted to hear :-) Cheers Martin ------------------------------------------------------ Martin Knoblauch email: k n o b i AT knobisoft DOT de www: http://www.knobisoft.de
