Glad that the article helped you.

We have set up our logging macros in such a way that we get the function name which generated the log for each line of the log file. So mentioning from which function the log got generated is totally redundant.
When a function I called returns failure, I generally log the function name which returned failure along with the error code and if possible a brief description of the error code.
Eg:

void myStupidFunction()
{
    char *fileName = "myFile.txt";
    File *pFile = fopen (fileName,"w");
    if(NULL == pFile)
    {
        LOG_ERROR("fopen failed for file:%s with error code:%d and error description:%s",fileName,errno,std::strerror(errno));
    }   
}
