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.
