DevOps Research and Assessment (DORA) key metrics API (ULTIMATE)

• Introduced in GitLab 13.10.
• The legacy key/value pair { "<date>" => "<value>" } was removed from the payload in GitLab 14.0. time_to_restore_service metric was introduced in GitLab 14.9.

All methods require at least the Reporter role.

The value field

For both the project and group-level endpoints above, the value field in the API response has a different meaning depending on the provided metric query parameter:

metric query parameter	Description of value in response
change_failure_rate	The number of incidents divided by the number of deployments during the time period. Available only for production environment.
deployment_frequency	The number of successful deployments during the time period.
lead_time_for_changes	The median number of seconds between the merge of the merge request (MR) and the deployment of the MR commits for all MRs deployed during the time period.
time_to_restore_service	The median number of seconds an incident was open during the time period. Available only for production environment.

NOTE: The API returns the monthly and all intervals by calculating the median of the daily median values. This can introduce a slight inaccuracy in the returned data.
