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_manager_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>.

-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
