NAME

       lights - DNSSEC-Tools Rollover Overview GUI Display

SYNOPSIS

         lights [options]

DESCRIPTION

       lights gives a very simple overview of the rollover status of a set of zones.  The
       rollover status counts are given in a "traffic light" display.  In contrast, blinkenlights
       gives a detailed display of the roll status of a set of zones.  lights gives very little
       control over rollerd, the way blinkenlights does.  lights can halt rollerd's execution
       only.

       The rollover status is retrieved in one of two ways.  By default, rollerd is contacted via
       the rollctl command.  Alternately, if the -rrf option is given, then zone status is read
       directly from a rollrec file.  The default method gets the status directly from rollerd
       and the user need not know the location of the relevant rollrec file.  However, that
       method will not get zone status until rollerd is available to respond to the information
       request.  Consequently, the alternate method allows lights to bypass communicating with
       rollerd and not having to wait for rollerd to be available.

       A window is created that has three colored sections - green, yellow, and red.  The green
       section displays a count of those zones that are in "normal" status; that is, they are not
       in rollover.  The yellow section displays a count of those zones that are in rollover.
       The red section displays a count of those zones that are in need of attention.  A common
       cause for this last state is because a zone is in phase 5 of KSK rollover and is waiting
       for its parent zone to publish the child's new DS record.

       Clicking on the color rows in the main window will bring up a dialog box that lists the
       zones in that state.  This list will not automatically update as zones change rollover
       state.

OPTIONS

       lights supports the following options.

       -interval wait-time
           Interval between checks of zone rollover status  By default, wait-time is given in
           minutes.  This can be adjusted by specifying one of the following time-unit suffixes.

           * s - seconds

           * m - minutes

           * h - hours

           Examples:

           * -interval 24 - 24 minutes

           * -interval 24s - 24 seconds

           * -interval 24m - 24 minutes

           * -interval 24h - 24 hours

       -rrf rollrec-file
           A rollrec file to be read for zone status.

       -labels
           Labels will be given for each color field in the GUI.

       -verbose
           Give verbose output.

       -help
           Give a usage message and exit.

       -Version
           Displays the version information for lights and the DNSSEC-Tools package.

REQUIREMENTS

       lights is implemented in Perl/Tk, so both Perl and Perl/Tk must be installed on your
       system.

KNOWN ISSUES

       The following are known issues.  These will be resolved in the fullness of time.

       •   Resizing the window leaves the color blobs in their original size.  This is an issue
           with the Tk widget used to display the color stripes.  Other display methods are being
           investigated...
