Commits Lead to Broken Builds shows the ratio of commits that led to broken builds compared to the total amount of commits at a specific date. Default time depth is 1 month up to the current date.
It indicates the effectiveness of a code quality quards. The greater this percentage the worse. Metric may help identify build problems as they occur, pointing the source of the error.
Chart shows % of commits which led to broken builds - Axis Y per job/pipeline day by day - Axis X. Legend on the top of the chart gives the latest value for each configured job/pipeline.
Commits led to broken builds = Ncommit_fail/Ncommit_all * 100 %,
where
Ncommit_fail - number of commits in failed builds
Ncommit_all - number of commits in all builds
Example for a particular date on a timeline:
| Given: total # of all builds on that day | 5 |
|---|---|
| Given: # of failed builds | 2 |
| Given: # of commits in all builds | 15 |
| Given: # of commits in failed builds | 3 |
| Calculated: Commits led to broken builds % | 3 / 15 = 0.2 = 20% = Amber |
RAG thresholds: Red - metric value > 50%, Amber - metric value > 10%, otherwise Green.
Data for the metric can be retrieved from Jenkins/GitLab CI. When using Jenkins make sure Git plug in is installed.
