This plugin has been deprecated since SonarQube 5.0 and it is no longer maintained since SonarQube 5.2


The Rules Compliance Index (RCI) Metric was deprecated in SonarQube 4.0 and is no longer available to be displayed in a dashboard. See SONAR-4755 for more details.

The Issues Density Plugin is the rebirth of the RCI Metric as a dedicated plugin, and allows interested users to bring this metric back to their dashboards.

The Issues Density Plugin comes also with the Weighted Issues Metric. This metric multiplies by a weight value the total number of issues for each severity level.


Your project has 8 Blockers Issues and 42 Major Issues, having a Weight Configuration equals to INFO=0;MINOR=1;MAJOR=3;CRITICAL=5;BLOCKER=10, the Weighted Issues Metric will be:

(8 Blockers * 10) + (42 Majors * 3) = 80 + 126 = 206


The RCI Metric is always positive and is defined as:

Max ( 1.0 - (Weighted Issues Metric / Number of Line of Code) * 100, 0.0 ) 


  1. Install the plugin through the Marketplace or download it into the SONARQUBE_HOME/extensions/plugins directory
  2. Restart the SonarQube server


You can change the Weight to apply for each severity level in the configuration of the plugin. The default value is INFO=0;MINOR=1;MAJOR=3;CRITICAL=5;BLOCKER=10

Go in Settings > General Settings > Issue Density : 


Issues Density Plugin comes with a new Widget : "Most Violated Components". This widget display the top X components having the highest Weighted Issues value.
