Publishing Custom Metric Data

A number of AWS services publish their own metrics in namespaces beginning with AWS/ You can also publish custom metric data using your own namespace (as long as it doesn’t begin with AWS/).

Prerequisites

Before you begin, we recommend you read Getting started using the AWS SDK for C++.

Download the example code and build the solution as described in Get started on code examples.

To run the examples, the user profile your code uses to make the requests must have proper permissions in AWS (for the service and the action). For more information, see Providing AWS credentials.

Publish Custom Metric Data

To publish your own metric data, call the CloudWatchClient’s PutMetricData function with a PutMetricDataRequest. The PutMetricDataRequest must include the custom namespace to use for the data, and information about the data point itself in a MetricDatum object.

Includes

#include <aws/core/Aws.h>
#include <aws/monitoring/CloudWatchClient.h>
#include <aws/monitoring/model/PutMetricDataRequest.h>
#include <iostream>

Code

        Aws::CloudWatch::CloudWatchClient cw;

        Aws::CloudWatch::Model::Dimension dimension;
        dimension.SetName("UNIQUE_PAGES");
        dimension.SetValue("URLS");

        Aws::CloudWatch::Model::MetricDatum datum;
        datum.SetMetricName("PAGES_VISITED");
        datum.SetUnit(Aws::CloudWatch::Model::StandardUnit::None);
        datum.SetValue(data_point);
        datum.AddDimensions(dimension);

        Aws::CloudWatch::Model::PutMetricDataRequest request;
        request.SetNamespace("SITE/TRAFFIC");
        request.AddMetricData(datum);

        auto outcome = cw.PutMetricData(request);
        if (!outcome.IsSuccess())
        {
            std::cout << "Failed to put sample metric data:" <<
                outcome.GetError().GetMessage() << std::endl;
        }
        else
        {
            std::cout << "Successfully put sample metric data" << std::endl;
        }
