              ovs-bugtool can collect a variety of relevant system
              information.  This option limits collection to Open vSwitch-
              specific categories.

              Include the logs with last modification time in the previous
              days days in the debug bundle. The number of log files
              included has a big impact on the eventual bundle size. The
              default value is 20 days.

BUGS         top

       ovs-bugtool makes many assumptions about file locations and the
       availability of system utilities.  It has been tested on Debian and
       Red Hat and derived distributions.  On other distributions it is
       likely to be less useful.
