说明

final public MongoDB\Driver\Server::getLatency(): ?integer

Returns the latency of this server in milliseconds. This is the client's measured » round trip time of a hello command.

参数

此函数没有参数。

返回值

Returns the latency of this server in milliseconds, or null if no latency has been measured (e.g. client is connected to a load balancer).

错误／异常

Throws MongoDB\Driver\Exception\InvalidArgumentException on argument parsing errors.

版本	说明
PECL mongodb 1.11.0	This method will return `null` if no latency has been measured. In earlier versions, an integer was always returned and an unset value might be reported as `-1`.

范例

示例 #1 MongoDB\Driver\Server::getLatency() example


<?php

$manager = new MongoDB\Driver\Manager("mongodb://localhost:27017/");

$rp = new MongoDB\Driver\ReadPreference(MongoDB\Driver\ReadPreference::RP_PRIMARY);
$server = $manager->selectServer($rp);

var_dump($server->getLatency());

?>

以上例程的输出类似于：

int(592)
