c - RRD with a high-precision?

Question

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?

Answer 1

rrdtool 中的步长是整数，因此不能小于一秒。但是更新可以带有毫秒精度的时间戳，并且会被正确处理。只是您存储样本的频率不能超过每秒一次。
