• The external services and servers will be monitored when they are slowing your work.
• Analyze the data statistics, identify specific instances and get the information on the stack trace and requests received on that particular process.
• Pageviews on your apps and app loading performance
• Monitor conversion rates, response times, click rates, downloads, and failure rates, which are called as AJAX calls for your web page.
