MongoDB::setProfilingLevel

(PECL mongo >=0.9.0)

MongoDB::setProfilingLevel — Sets this database's profiling level

说明

public int MongoDB::setProfilingLevel ( int $level )

This changes the current database profiling level.

This function is equivalent to running:

  <?php

 public 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.
