Deployment history

  • Article

Deployment history is a deployment pipelines feature that enables reviewing the past deployments in your pipeline. The feature is designed as a log that lists all the past deployments in the pipeline.

You can use the deployment history log, to check the health of your pipeline, and to troubleshoot problems that occurred during previous deployments.

When you perform a deployment, you can use the built-in option to leave notes, to add additional information to each deployment. Later, when you look back at your deployment history, the notes can help you understand what happened during each deployment.

Deployment information

To view the pipeline's deployment history, select Deployment history.

The deployment history log is formatted as a table. Each row represents a single deployment, and the columns list the following information per deployment:

  • Deployed to - The target stage of the deployment.

  • Date and time - The date and time of the end of the deployment.

  • Deployed by - The person (or service principal) who performed the deployment.

  • Items - The items column indicates the differences between the items in the source and target stage. All labels except failed deployment, refer to the items in the target stage before the deployment takes place. These labels show the number of items from that category that were deployed. You can select the label to view a list of all the items in that category. If a label isn't showing, no deployed items fit that category.

Considerations and limitations

The following section lists the deployment history limitations.

  • Detailed information is displayed from June 2022. Prior to this date, summarized information is displayed.

  • Deployment history displays the name of the item during deployment. When you change an item's name, deployment history treats it as a new item. In such cases, the item with the changed name will appear in the log for the first time, after it's deployed.
