Start the system analysis function by clicking on the Fiori tile for System Analysis:
Select the system you need to analyze for issues in the scope selection screen. In the first case we take an ABAP stack with time frame of the last 6 hours:
This overview might be bit overwhelming the first time. But you can see the performance was bad in the middle of the day (see top middle graph on average response time). Bottom middle graph shows CPU of some application servers was at 100%. And at the same time there were many dumps (right middle graph). This gives a clear direction were to look for issues.
The system analysis overview adjusts the information automatically to its content. This is the information for a HANA system:
Note here that the time frame here is from the last month. This is for getting longer term overview of the system behaviour. You can get this longer term overview by changing the time frame of the system analysis tool.
You can select a specific view from the page catalog list on the left button bar on the screen:
So you can easily filter the specific page for the type of system you need to analyze.

Choose the menu option for ABAP performance:
The performance overview will now open:
You can click on many items now to get to the details.
Setup of Performance Analysis
To make the above function work;, click on the settings wheel and click on the Configure Collection of ABAP performance data:
Make sure the system you need analysis data from is activated correctly.
If the data collection is not ok, check the Collector Status button and Agent logs. Also check the backend system user used to see if this user has sufficient authorization to fetch the required data.
