Top Forums Shell Programming and Scripting Average of multiple time-stamped data every half hour Post 302920815 by terrychen on Monday 13th of October 2014 06:15:22 AM

Hi Don,

Thanks a lot for your reply.

Regarding your question, if this is a homework assignment, it's not. I collect a stream of data and use excel to take an average since I am not a programmer or someone with Unix background. Maybe it's about time I can learn some perl etc. and make my life a little easier than having to use excel to take an average.

Like you said, I was wrong in saying the last item on the value for time is millisecond. It actually goes from 0 till 9 for the next value and then the value for second increases by one.

Also, I am trying to calculate average of A values and average of B values for the duration of 30 minutes.

Regards,
Terry

NAME
tload - graphic representation of system load average SYNOPSIS
tload [-V] [-s scale] [ -d delay ] [tty] DESCRIPTION
tload prints a graph of the current system load average to the specified tty (or the tty of the tload process if none is specified). Options The -s scale option allows a vertical scale to be specified for the display (in characters between graph ticks); thus, a smaller value rep- resents a larger scale, and vice versa. The -d delay sets the delay between graph updates in seconds. FILES
/proc/loadavg load average information SEE ALSO
ps(1), top(1), uptime(1), w(1) BUGS
The -d delay option sets the time argument for an alarm(2); if -d 0 is specified, the alarm is set to 0, which will never send the SIGALRM and update the display. AUTHORS
