This metric will highlight the percentage of code commits made to your default branch that do not have a related pull request. Based on the date of commit the default view is to plot this percentage over time, as below:
Breakdown and Filtering Options
As with all our metrics we have a broad selection of breakdowns and filters to allow you to tailor Commits without a Pull Request to your various needs.
The first two options below are based on the commit data itself - Committer and Repository. Useful to be able to drill down on where this PR process is being used or not.
The other options, prefixed "Ticket", are pulling in the fields for related tickets that are referenced in those commits. For further detail see Commits without a Ticket Reference.
So where ticket linking is in place you'll be able to gain unique perspectives of this metric based on attributes like Issue Type, Epic Link or Fix Version etc.
