ITT API Reference Collector

This is a reference implementation of the ITT API dynamic part that performs tracing data from ITT API function calls to log files.

To use this solution, build the collector as a shared library and point the full library path to the INTEL_LIBITTNOTIFY64 or INTEL_LIBITTNOTIFY32 environment variable:

On Linux

make
export INTEL_LIBITTNOTIFY64=<build_dir>/libittnotify_refcol.so

On FreeBSD

make
setenv INTEL_LIBITTNOTIFY64 <build_dir>/libittnotify_refcol.so

By default, log files save in the Temp directory. To change the location, use the INTEL_LIBITTNOTIFY_LOG_DIR environment variable:

On Linux

export INTEL_LIBITTNOTIFY_LOG_DIR=<log_dir>

On FreeBSD

setenv INTEL_LIBITTNOTIFY_LOG_DIR <log_dir>

This implementation adds logging of some of the ITT API function calls. Adding logging of other ITT API function calls is welcome. The solution provides 4 functions with different log levels that take printf format for logging:

LOG_FUNC_CALL_INFO(const char *msg_format, ...);
LOG_FUNC_CALL_WARN(const char *msg_format, ...);
LOG_FUNC_CALL_ERROR(const char *msg_format, ...);
LOG_FUNC_CALL_FATAL(const char *msg_format, ...);
