bpftrace (DTrace 2.0) for Linux 2018

Brendan Gregg

Screenshot: tracing read latency for PID 181: # bpftrace -e 'kprobe:vfs_read /pid == 30153/ { @start[tid] = nsecs; } kretprobe:vfs_read /@start[tid]/ { @ns = hist(nsecs - @start[tid]); delete(@start[tid]); }'. in 2004, so I have to think back to that time to understand it. It's shaping up to be a DTrace version 2.0: I wrote seeksize.d
