Enable Speed Index

Speed Index (SI) is a measure to determine the page load performance by calculating how quickly the page contents are visibly populated. Speed Index is dependent on size of the Viewport and it is expressed in milliseconds. Lower page load time improves the Speed Index score.

In Splunk AppDynamics SaaS, you can enable Speed Index while configuring the JavaScript Agent. Analyze the Speed Index scores and improve the page performance.

To view the Speed Index metrics, enable Speed Index while configuring the JavaScript Agent and inject the adrum.js script.

<head>
    <script type='text/javascript' charset='UTF-8'>
        (function(config){
            config.enableSpeedIndex = true;
            })(config.xhr || (config.xhr = {}));
        })(window["adrum-config"] || (window["adrum-config"] = {}));
    </script>
    <script src='//cdn.appdynamics.com/adrum/adrum-latest.js' type='text/javascript' charset='UTF-8'></script>
    ...
</head>
