## Task 2

In the second task, you will need to find the reason for some poorly performing transactions. The performance issue becomes visible after the first task is fixed. So it may take a bit of time until you can clearly see it in the charts. It's also okay to reduce the time window of the Kibana charts to only get and see the data after the fix of task 1. 

You will know that you’ve fixed the issue when there is no transaction that takes longer than a second.

In order to find the issue, you need to navigate to the APM Service of the Python App.
The Python App only has one trace to analyze. Navigate into that trace and perform the Latency correlation. Make sure you include enough data. The best way would be to have 15 minutes of data after you fixed the issue in Task 1. However, if you are faster, you can use the time picker in Kibana to only use more recent data. 

When there is enough data, you will find the concrete next step to do in order to fix the performance issue.
