Enable Additional Logs in Azure Pipeline Execution With This Guide
One of the most important aspects in the Azure DevOps life cycle Pipeline development is to have tools and techniques in place to find out the root cause of any error that would have occurred during the Azure DevOps pipeline execution. In this article, we will learn how to review the logs that helps in troubleshoot for any errors in the Pipelines by enable additional logs in Azure pipeline execution
By default, Azure DevOps pipeline provides logs which provide information about the execution of each step in the pipeline. In case of any error or need to more information to debug that time the default logs wouldn’t help you in understanding what went wrong in the pipeline execution. In those cases, it would be helpful if we get more diagnostic logs about each step in the Azure DevOps pipelines.
Below are the two different techniques to enable the feature of getting additional logs.
Enable System Diagnostics logs for specific execution of pipeline.
If you would like to get additional logs for a specific pipeline execution then you need to do is enable the Enable System Diagnostics check box as shown below image and click on the Run button.
Enable System Diagnostics logs for All execution of pipeline
If you always want to enable System Diagnostics to capture the Diagnostics trace for cases where the pipeline executed automatically (Continuous Integration scenarios), then you need to create a variable in the pipeline with the name system.debug and the set the value to true as shown below.
System.debug = true (variable helps us to generate diagnostics logs in during the execution of pipelines)System.debug = False (variable helps us to not generate diagnostics logs in during the execution of pipelines)
Once we set the value of system.debug to true in our variable group (which referred in our pipeline), then the pipeline starts showing additional logs in the purple color as shown below.
System.debug = true
System.debug = false
Note: You like to view the logs without any colors, you can click on the View raw log button which opens up the logs in a separate browser window and you can save if required.
Download Logs from Azure pipeline:
In case if you like to share the logs to some other teams who doesn’t have access to your pipeline, you can download the logs by clicking on the Download Logs button in the Pipeline Summary page as shown below and you can share.
