OutSystems Platform collects analytics about the performance of your applications, so that you can easily pinpoint and fix performance bottlenecks.
In the infrastructure management console, you can explore the performance of the apps. You can drill down and see the performance of an application on the:
This allows you to analyze the performance of your apps from end to end.
During the last couple of days, we received emails complaining about the performance of the 'Field Services' mobile app. End-users are complaining about getting timeout messages when loading the 'Dashboard' screen.
Analytics is enabled for all applications in Production, so we can find out what's going on. In the infrastructure management console, navigate to the 'Analytics' tab.
Looking at the 'Screens Getting Slower' card (check the image above), we can confirm that the performance of the 'Dashboard' screen in the 'Field Services' mobile app has decreased during the last week. Its APDEX value has dropped by 17%. Select the 'Dashboard' screen to see more details.
We can see in the actions of the screen that the 'Preparation' action has a low APDEX score.
Click on the 'Preparation' screen to see the more information about this action.
On the 'Response Time Breakdown' card, check that most of the time is spent on the server.
This means that the problem is probably on the server-side. Click on the 'Server' tab to check what's causing the server to take so long.
On the 'Slow Calls' card, we can see that the 'GetWorkOrdersByDate' query is slow. This is probably the root cause of our problem.
We can now contact the DBA and let them know this query is having a negative impact on the user experience, and should be tuned right away.
