Debug log

Debug logs starting with [ DEBUG ] will be shown after this option is set to ON, and each log has prefix in format source_file_name:line_num function() indicating the position of the log in source code.

Environment variable OV_CPU_DEBUG_LOG controls which debug logs to output by combining patterns, typical examples of usages are:

  • not define it: no debug logs will be output
  • - : all debug logs will be output
  • graph.cpp:798;InitEdges : only debug logs from "graph.cpp:798" and function "InitEdges" are output
  • -graph.cpp:798;InitEdges : only debug logs from specified places are not output

Environment variable OV_CPU_DEBUG_LOG_BRK can be set to some keywords or a full log line seen previously, if any debug log match with the content in this variable, an int3 instruction will be executed to trigger breakpoint trap if it's running inside a debugger.
