lua-usdt
Lua bindings for libusdt[1].
Build with first:
cd libusdt
make
cd ..
and then:
luarocks --local build usdt-0.1-1.rockspec USDT_INCDIR=libusdt
Test:
sudo dtrace -Z \
-n 'lua*:lmod:foo:cprobe{ printf("%s %s %s %s %s %s %s %s %s %s", copyinstr(arg0), copyinstr(arg1), \
copyinstr(arg2), copyinstr(arg3), copyinstr(arg4), copyinstr(arg5), copyinstr(arg6), \
copyinstr(arg7), copyinstr(arg8), copyinstr(arg9)) }' \
-n 'lua*:lmod:foo:iprobe{ printf("%d %d %d %d %d %d %d %d %d %d", arg0, arg1, arg2, arg3, arg4, \
arg5, arg6, arg7, arg8, arg9) }' \
-c 'lua test.lua'
The output of this should be along the lines of:
dtrace: description 'lua*:lmod:foo:cprobe' matched 0 probes
dtrace: description 'lua*:lmod:foo:iprobe' matched 0 probes
dtrace: pid 33227 has exited
