How can I configure OpenNMS to use RRDTool instead of JRobin for latency and performance data?

Do not do this unless you fully understand the implications, which include losing all your historical latency and performance data and possibly decreased performance of openNMS on your system. You will need the appropriate platform-specific JNI library to allow openNMS to communicate with the C-language RRDTool libraries. Instructions for making this change are in the comments at the top of file rrd-configuration.properties.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
