If the bandwidth drops from some level a warning should be generted. There is some plugin that do this? If not, which approach do you suggest to get this information? I need to know the roud-trip delay time (RTT) but for a tcp connection. There is such a TCP-ping? Still the most important is to know the bandwidth capacity between the 2 servers.
