Hi, Does ZFS has support for kstats? If I want to extract information like no of files commited to disk during an interval, no of transactions performed, I/O bandwidth etc, how can I get that information? Regards, -Atul

Peter,
How do I get those stats programatically? Any clues?

Atul, libkstat(3LIB) is the library. "man -s 3KSTAT kstat" should give a good start. Regards, Sanjeev. Atul Vidwansa wrote:> Peter, > How do I get those stats programatically?
