Is it possible to use RRDs with a high-precision? And by high-precision I mean e.g. in the range of milli-seconds.
If not, are there equally good alternatives to RRD with a C API that work under Linux?

Doesn't rrdtool do what you want? You can compile against librrd. – cha0site Apr 19 '12 at 15:08

No, in the source code it is stated "step size should be no less than one second". – user1344105 Apr 19 '12 at 15:29

the step size in rrdtool is an integer and thus can not be less than a second. BUT updates can carry a ms precision time stamp and will be handled correctly. It is just that you can not store samples more often than once per second.
