(PECL mongo >=0.9.0)
MongoDB::setProfilingLevel — Sets this database's profiling level
说明
public MongoDB::setProfilingLevel
( int $level
) : int
This changes the current database profiling level.
This function is equivalent to running:
<?phppublic function setProfilingLevel($level) { return $this->command(array('profile' => $level));}?>
The options for level are 0 (off), 1 (queries > 100ms), and 2 (all queries). If you would like to profile queries that take longer than another time period, use the database command and pass it a second option, the number of milliseconds. For example, to profile all queries that take longer than one second, run:
<?php$result = $this->command(array('profile' => 1, 'slowms' => 1000));?>
Profiled queries will appear in the system.profile
collection of this database.
参数
level- Profiling level.
返回值
Returns the previous profiling level.
