Hi, I'm the main developper on rrd4j. I've been very busy lately on this project, and talked with Tarus Balog about licensing issue.
I'm happy that you seems to be open about an Apache License, and look forward for more exchange between our projets. I have already a lot of improvement and bug fix in rrd4j, with some heavy perfomance one by changing the disk layout of rrd files. The pool is more scalable I think. For now, I have 3 open projects on rrd4j, and wanted to inform you about them, I hope it can help you improving jrobin and opennms. - The first one is an upgraded of the API to be more on sync with rrdtool, and it made a confusion in the API between consolidation function and VDEF, I hope I improved the situation, it can also provide access to custom VDEF. It's currently in the branch master of rrd4j and when it will be enought tested I plan to release it as rrd4j 2.3 - The backend API was not very rich, it provides only raw byte storage. I'm trying to write something more high level, that should allow me to write a cassandra back end wich is a very important goal. It should also be easier to add custom backends as plugin. It's in the NewBackEnd branch. When it will be finished and tested, I plan to release it as rrd4j 3. - The JRobinRrdStrategy strategy expose only a very small subset of what rrdtool can provide, that's a pity and don't help increase jrobin/rrd4j usage, writing a RRD4JRrdStrategy is not a difficult task, just tedious, I have started it. I have also written a caching backend for rrd4j, that can use directio on Solaris/Linux plateform, for high performance collect. For all of this, if any of you is interested, help, comments and ideas are welcome, and I'm open to any exchange you might be intersted in.
