cloudwatch.php

<?php

// Include the SDK using the Composer autoloader
require 'vendor/autoload.php';

use Aws\CloudWatch\CloudWatchClient;

$client = CloudWatchClient::factory(array(
        'key'    => 'keyをね',
        'secret' => '秘密のやつをここに',
        'region'  => 'ap-northeast-1'
));

$dimensions = array(
    array('Name' => 'InstanceId', 'Value' => 'i-hogehoge(コンソールにのってるID)'),// HOGE SERVER
    array('Name' => 'InstanceId', 'Value' => 'i-hogehoge(コンソールにのってるID)'),// HOGEHOGE SERVER
);

$result = $client->getMetricStatistics(array(
    'Namespace'  => 'AWS/EC2',
    'MetricName' => 'CPUUtilization',
    'Dimensions' => $dimensions,
    'StartTime'  => strtotime('-1 days'),
    'EndTime'    => strtotime('now'),
    'Period'     => 3000,
