Kalibro Metrics aims to improve the use of source code metrics. It is designed for easy integration with a metric collector tool and show the results in a friendlier way. For that, it allows a metric specialist to create a configuration of thresholds associated with qualitative evaluation, including comments and recommendations. These configurations are used to enhance metric results interpretation.

Features provided by Kalibro Metrics include:

• Creation of configurations, i.e. a set o metrics for being used in the evaluation of a project
• Creation of new metrics (via Javascript) based on the ones provided by the metric collector tool
• Creation of ranges associated to a metric and a qualitative evaluation (may be plain text or HTML)
• Calculation of statistics results for higher granularity modules (e.g. average LOC of classes inside a package)
• Possibility of exporting results to a CSV file
• Calculation of a grade for the project, based on given weights for metrics and grades for ranges (allows project comparisons)
• Possibility of making interpretation more user-friendly associating colors to ranges
• Download of source code from remote zip file, tarball or Subversion repository

Kalibro Metrics is delivered with the proper configuration to run using Analizo - a free and multi-language toolkit - as the source code analysis tool. Analizo supports the extraction and calculation of a fair number of source code metrics, generation of dependency graphs, and software evolution analysis. It efficiently parses source code written in C, C++ and Java.

For Qualipso project was developed the Kalibro Service provides Kalibro Metrics features through a Web Service interface. It was created for integration with Spago4Q – a free platform to measure, analyze and monitor quality of products, processes and services. Kalibro Service is integrated to Spago4Q through the KPI model, extractor and extraction process configuration provided here (Kalibro-Documents.zip file).
