CW: CloudWatchのNamespaceとMetricNameの一覧を取得する (PHP)

AmazonCloudWatch::get_metric_statistics で、CloudWatchに溜まったメトリクスを取得するためには、引数として、取得対象のメトリクスの NamespaceとMetricNameを指定する必要がある。

ということで、AmazonCloudWatch::list_metricsを使って、とりあえず今取得できるMetricsの一覧を取得し、その中からNamespaceとMetricNameを抜いてみる。

<?php
require_once '/usr/share/pear/AWSSDKforPHP/sdk.class.php';
$cw = new AmazonCloudWatch();
$cw->set_region(AmazonCloudWatch::REGION_TOKYO);

$res = $cw->list_metrics();
$mets = $res->body->ListMetricsResult->Metrics->member;
$tree = array();
foreach ($mets as $met ){
    $ns = $met->Namespace;
    $mn = $met->MetricName;
    print($ns .":". $mn ."\n");
}
?>

というかんじ。実行結果は

$ php getcw.php
