Hi @indratan,
The management reporting becomes available in the Enterprise Edition of SonarQube.
Before we used the Enterprise Edition, we exported the figures from SonarQube using the Web API (REST). Check this URL for documentation: https:///web_api.
We loaded the figures on monthly basis into a separate database and analyzed them with Microsoft PowerBI.
We still do so, because we combine the figures from SonarQube with Metrics from other systems, e.g. Vulnerability scan of 3rd Party libraries.
