AppNeta TraceView (formerly Tracelytics) is a third-party service providing analysis and profiling to help identify performance problems within your application.
TraceView can monitor Drupal sites without the tracelytics module being enabled, but doing so allows some of TraceView's features to be deployed more rapidly within a Drupal environment. In order to configure the tracelytics module to take any actions, you must visit its administrative settings page once it is installed and enable each of the settings using the provided form. No other configuration is required, provided your web server has been configured for profiling by TraceView.
