What are the benefits of application monitoring tools?

Application monitoring tools, such as New Relic, help you to monitor live Drupal and other PHP applications, troubleshoot issues, and tune applications for optimal performance. For example, you might experience delay while accessing your site. This issue might occur when your PHP execution time is high. However, you can be sure about the exact issue only when you leverage such tools. Acquia recommends that you enable New Relic to troubleshoot issues with your application.
