Examples of urandomread.py, the Linux eBPF/bcc version. To demonstrate this, the following workload was issued: # dd if=/dev/urandom of=/dev/null bs=1k count=5 While urandomread.py was tracing in another session: # ./urandomread.py TIME(s) COMM PID GOTBITS 22592556.392825000 dd 14228 8192 22592556.392949000 dd 14228 8192 22592556.393068999 dd 14228 8192 22592556.393183999 dd 14228 8192 22592556.393298000 dd 14228 8192 The GOTBITS of 8192 matches the workload of 1 Kbyte (8 Kbit) reads. This program was really written as a simple example of tracing a tracepoint.
