Hudson understands the Cppcheck report XML format. When this option is configured, Hudson can provide useful information about results in different views: historical result trend, analysis reports.

You need to set up your build to run Cppcheck in order to use this feature - this Hudson plug-in does not perform the actual analysis! This plug-in is not invoked for failed builds, it is only called for stable or unstable builds (i.e., a build with failed tests).
