    24 
    25                 The Job Archiving Daemon (optionally).

     24
     25                The Job Archiving Daemon.
    2626
    2727                Listens to Ganglia's XML stream and archives the job and node statistics.
     
    3333
    3434                Optionally: You can either choose to use this daemon if your users have use for it.
    35                 As it can be a heavy application to run - even though optimized (staged/buffered writes
    36                 and multi threaded) - and not everyone may have a need for it.

     36
     37                - Multithreaded:        Will not miss any data regardless of (slow) storage
     38
     39                - Staged writing:       Spread load over bigger time periods
     40
     41                - High precision RRDs:  Allow for zooming on old periods with large precision
     42
     43                - Timeperiod RRDs:      Allow for smaller number of files while still keeping advantage
     44                                        of small disk space
    3745               
    3846        * web
     
    4452
    4553                It does this in a similar layout/setup as Ganglia itself, so the navigation and usage is intuitive.
    46                
     54
     55                - Graphical usage:      Displays graphical cluster overview so you can see the cluster (job) state
     56                                        in one view/image and additional pie chart with relevant information on your
     57                                        current view
     58
     59                - Filters:              Ability to filter output to limit information displayed (usefull for those
     60                                        clusters with 500+ jobs). This also filters the graphical overview images output
     61                                        and pie chart so you only see the filter relevant data
     62
     63                - Archive:              When enabling jobarchived, users can go back as far as recorded in the database
     64                                        or archived RRDs to find out what happened to a crashed or old job
     65
     66                - Zoom ability:         Users can zoom into a timepriod as small as the smallest grain of the RRDS
     67                                        (typically up to 10 seconds) when a jobarchived is present
