This option can be used to enable or disable trace-level debug logging in
the extension (and libmongoc).
Specify an empty string, "0",
"off", "no", or
"false" to disable logging.
Specify "stderr" or "stdout" to log
to stderr or stdout, respectively.
Specify "1", "on",
"yes", or "true" to log to a new
temporary file within the default system temp directory (i.e.
sys_get_temp_dir).
Specify any other string to log to a new temporary file within that
directory. If the directory cannot be used, the default system temp
directory will be used instead.
Note:
Please note that the debug log can contain sensitive information, such
as credentials to the MongoDB server and full documents written to or
read from the server. Please review any debug logs before sharing them
with other people.
