What you’ll learn

This tutorial details how to use tracing for monitoring, analysing, debugging, and optimising your code. Tracing helps you to:

• detect failures and the place where they occur;
• and understand what causes the poor performance of the application.

Prerequisites

• Create a New Application
• Create a New Application Component
• Deploy your Application

Steps

1. Find the "Logging&Tracing" section in the sidebar menu and go to the "Tracing" option.

• Here you have different ways of finding an application component:
  • you can search your application components by traceID;
  • or you can search through the expandable menu.

2. Search by traceID.

• First, get the traceID.
• Open the chosen application component in the browser, make a request in swagger, and copy the traceID from the response:

• Paste the traceID into the search field and click on the "Search" button.

• There you will find the analysis of the tracing system in the chosen application:

3. Search through the expandable menu

• You can click through this menu and find the trace that you are looking for:

• There you will find the analysis of the tracing system in the chosen application:

4. Once you've got the results, you can expand each of them to see more details:

• You can click on "Logs for this span" button to see all logs for this component:

• You can also add |="your_trace_id" (for example: |="8f23f1ac55bd287553370fdd783f88a8") after the log command that you've already had. This will show all logs for this component only for this traceID.

5. You can also use the search field to find the specific component. Result will be highlighted in yellow:
