       ktap - lightweight script-based dynamic tracing tool for Linux


       ktap [options] file [script args] -- cmd [args]
       ktap [options] -e one-liner  -- cmd [args]


   Options and arguments:
       -o file
              : send script output to file, instead of stderr

       -p pid : specific tracing pid

       -C cpu : cpu to monitor in system-wide

       -T     : show timestamp for event

       -V     : show version

       -v     : enable verbose mode

       -q     : suppress start tracing message

       -d     : dry run mode(register NULL callback to perf events)

       -s     : simple event tracing

       -b     : list byte codes

       -le [glob]
              : list pre-defined events in system

       -lf DSO
              : list available functions from DSO

       -lm DSO
              : list available sdt notes from DSO

       file   : program read from script file

       -- cmd [args]
              : workload to tracing


       To make ktap work, firstly you need to load "ktapvm" module:

              modprobe ktapvm
