[dtrace-discuss] CPU time and IO time

Hi, I am trying to characterize some benchmark programs using dtrace. The first step is to determine the time that a program spends on the CPU (doing computations), and the time it spends doing IO. The cpu time can be easily determined using the on-cpu and off-cpu probes. I am having

Re: [dtrace-discuss] CPU time and IO time

The easiest way to do this is using the sleep/wakeup probes in the sched provider. From the process/thread perspective, once they issue an IO, they sit on a sleep queue until the IO is completed, at which point they're issued a wakeup. io:start/io:::done is usefull for a system view, but that's
