NAME

dtrace - Dtrace compatibile user application static probe generation tool.

SYNOPSIS

dtrace -s file [OPTIONS]

DESCRIPTION

The dtrace command converts probe descriptions defined in file.d into a probe header file via the -h option or a probe description file via the -G option.

OPTIONS

-h: generate a systemtap header file.
-G: generate a systemtap probe definition object file.
-o file: is the name of the output file. If the -G option is given then the output file will be called file.o; if the -h option is given then the output file will be called file.h.
-C: run the cpp preprocessor on the input file when the -h option is given.
-I file: give this include path to cpp when the -C option is given.
-k: keep temporary files, for example the C language source for the -G option.
--types: generate probe argument typedef information when the -h option is given.

EXAMPLES

Systemtap is source compatible with dtrace user application static probe support. Given a file test.d containing:

provider sdt_probes 
{
  probe test_0 (int type);
  probe test_1 (struct astruct node);
};
struct astruct {int a; int b;};

Then the command "dtrace -s test.d -G" will create the probe definition file test.o and the command "dtrace -s test.d -h" will create the probe header file test.h Subsequently the application can define probes using

#include "test.h"
 ...
struct astruct s;
 ...
SDT_PROBES_TEST_0(value);
 ...
SDT_PROBES_TEST_1(s);

The application is linked with "test.o" when it is built.
