This package provides read-only access to natives RRD file. Currently this can read RRD files that were generated big or little endian machines, 32 or 64 bits word, and 4 or 8 bytes alignment. So it's know to work on a least

• x86 Linux
• x86_64 Linux
• x86_64 Solaris
• sparc v8 (32 bits) Solaris
• sparc v9 (64 bits) Solaris

But it should work on other environments too.

Typical usage:

RRDatabase db = new RRDatabase("native.rrd");
RrdGraphDef() gd = RrdGraphDef();
Calendar endCal = Calendar.getInstance();
endCal.set(Calendar.MILLISECOND, 0);
Calendar startCal = (Calendar) endCal.clone();
startCal.add(Calendar.DATE, -1);
DataChunk chunk = db.getData(ConsolidationFunctionType.AVERAGE, startCal.getTime(), endCal.getTime(), 1L);
for(String name: db.getDataSourcesName()) {
    gd.datasource(name, chunk.toPlottable(name));
}
