checksysreport performs some automatic tests against a directory containing an untarred Red Hat Enterprise Linux sysreport. You will need a valid Red Hat Network login in order to use it, as it fetches information from RHN using the RHN API (see https://rhn.redhat.com/rpc/api/). A graphical tool, yadarh, is also included: it uses the cache generated by checksysreport to display RPMs in a given channel and lets you browse them to have a list of errata and new entries in changelogs that come with other versions of the same package.
