Hi, We need to graph a COUNTER (as input) but for output, instead of a rate of change, we simply need the difference against the previous reading (instead of difference against the previous reading divided by the polling period in seconds, as the existing COUNTER data type of RRDTool).
So, we need to create a new Data Type. Also for Consolidation, we would like to simply add all the values, so a new Consolidation Function is needed as well (in addition to the existing AVERAGE, MIN, MAX, LAST). The use case is we would like to have a total of all the count over the measurement period (5 mins, 30 mins, 1 hour, ...). So we need a total, not a rate for 5 mins, then for 30 mins, 1 hours ... and so on. We've been using Cacti, which uses RRDTool so we have a solid understand of what RRDTool can do and can not do. However, we have never tried to develop code for RRDTool before. Please let us know any coding guidelines, patch submission process ... anything to help us create a new Data Type and CF, make sure the graph generation is still working, being able to patch our current RRDTool, contribute to your code repository so the next release of RRDTool will have the new feature built-in. Any of these information will be very appreciated.
