Publishing Custom Metrics in Amazon CloudWatch with AWS SDK for PHP Version 3

Metrics are data about the performance of your systems. An alarm watches a single metric over a time period you specify. It performs one or more actions based on the value of the metric, relative to a given threshold over a number of time periods.

The following examples show how to:

All the example code for the AWS SDK for PHP Version 3 is available here on GitHub.

Credentials

Before running the example code, configure your AWS credentials, as described in Credentials for the AWS SDK for PHP Version 3. Then import the AWS SDK for PHP, as described in Basic Usage Patterns of the AWS SDK for PHP Version 3.

Publish Metric Data

Imports

require 'vendor/autoload.php'; use Aws\CloudWatch\CloudWatchClient; use Aws\Exception\AwsException;

Sample Code

$client = new CloudWatchClient([ 'profile' => 'default', 'region' => 'us-west-2', 'version' => '2010-08-01' ]); try { $result = $client->putMetricData(array( 'Namespace' => 'string', 'MetricData' => array( array( 'MetricName' => 'string', //Timestamp : mixed type: string (date format)|int (unix timestamp)|\DateTime 'Timestamp' => time(), 'Value' => integer, 'Unit' => 'Kilobytes' ) ) )); var_dump($result); } catch (AwsException $e) { // output error message if fails error_log($e->getMessage()); }

Create an Alarm

Imports

require 'vendor/autoload.php'; use Aws\CloudWatch\CloudWatchClient; use Aws\Exception\AwsException;

Sample Code

$client = new CloudWatchClient([ 'profile' => 'default', 'region' => 'us-west-2', 'version' => '2010-08-01' ]); try { $result = $client->putMetricAlarm(array( // AlarmName is required 'AlarmName' => 'string', // MetricName is required 'MetricName' => 'string', // Namespace is required 'Namespace' => 'string', // Statistic is required //string: SampleCount | Average | Sum | Minimum | Maximum 'Statistic' => 'string', // Period is required 'Period' => integer, 'Unit' => 'Count/Second', // EvaluationPeriods is required 'EvaluationPeriods' => integer, // Threshold is required 'Threshold' => interger, // ComparisonOperator is required // string: GreaterThanOrEqualToThreshold | GreaterThanThreshold | LessThanThreshold | LessThanOrEqualToThreshold 'ComparisonOperator' => 'string', )); var_dump($result); } catch (AwsException $e) { // output error message if fails error_log($e->getMessage()); }
