MongoDB::getProfilingLevel — Gets this database's profiling level
This returns the current database profiling level.
The database profiler tracks query execution times. If you turn it on (say, using MongoDB::setProfilingLevel() or the shell), you can see how many queries took longer than a given number of milliseconds or the timing for all queries.
Note that profiling slows down queries, so it is better to use in development or testing than in a time-sensitive application.
This function is equivalent to running:
<?php
public function getProfilingLevel() {
return $this->command(array('profile' => -1));
}
?>
此函数没有参数。
Returns the profiling level.
