NAME

       work_queue_graph_log - plots Work Queue statistics logs.

SYNOPSIS

       work_queue_graph_log [options] work-queue-log

DESCRIPTION

       work_queue_graph_log  is a script to plot some of the statistics from a Work Queue log, as
       generated  by  work_queue_specify_log  from  the  C  and  Perl  Work  Queue  APIs,  or  by
       q.specify_log from the Python Work Queue API. It assumes the availability of gnuplot.

       work_queue_graph_log generates four plots, all with timestamp as the independent variable:

       time:
           timestamp,     total_send_time,     total_receive_time,    total_transfer_time,    and
       total_master_time. (The last two generated by the script, not in the log.)

       time-log:
           log-scale version of times, plus total_execute_time.

       tasks:
           total_tasks_waiting, total_tasks_running, total_workers_connected, total_workers_busy,
       and total_cores

       tasks-log:
           log-scale version of tasks, plus total_complete_tasks.

OPTIONS

        -o <prefix-output>
              Generate  prefix-output.{time,time-log,tasks,tasks-log}.<output-format>. Default is
              <work-queue-log>.

        -c <gnuplot-path>
              Specify the location of the gnuplot executable. Default is gnuplot.

        -r <range>
              Range of time to plot, in time units (see -u) from the start of execution.  Of  the
              form: min:max, min:, or :max.

        -T <output-format>
              Set  output format. Default is png. If "text", then the gnuplot scripts are written
              instead of the images.

        -u <time-unit>
              Time scale to output. One of s,m,h or d, for seconds, minutes (default),  hours  or
              days.

        -h    Show help text.

EXAMPLES

       General use:

               % work_queue_graph_log mylog
               % ls mylog*.png
               mylog.tasks.png mylog.tasks-log.png mylog.time.png mylog.time-log.png

       Plot up to the eleventh hour:

               % work_queue_graph_log -u h -r :11 mylog

       Generate script text:

               % work_queue_graph_log -Ttext mylog
               % ls mylog*.gnuplot
               mylog.tasks.png.gnuplot mylog.tasks-log.png.gnuplot mylog.time.png.gnuplot mylog.time-log.png.gnuplot

       Specify gnuplot path:

               % work_queue_graph_log -c/some/dir/bin/gnuplot mylog

BUGS

       •   Some formats need a special setup for their gnuplot output terminal. -T blindly passes
           the output format
