trying different combination but to no avail. Thank you
Since you want to print an average every time you print a total for a set, you don't need two functions to print the total and the average -- just add another printf statement in the print_total function. If you add a new function, you need to call that function when you want the code that it defines to be run. The statement in your code:
Code:
        average total/NR

doesn't assign a value to any variable and just performs two calculations throwing away the results. the second calculation divides the current value of the total variable by the current input file line number (NR). It would seem that you need to be able to determine how many input lines you have in each set to get the average value of the value of the values in that set.

Why are you using substr($1, 1, 7) if you want to match the 1st 4 characters in the 1st field. (Have you changed your requirement to match the 1st 7 characters of the 1st field?)

Do you understand the difference between what you did and what you see in the following revision of my (commented) suggestion:
Code:
awk '	# Invoke awk and start the script specifying actions to be performed.
function print_total() {
	# Define function to print the total and average acccumulated for the
	# previous set of lines with the same four characters at the start of
	# the 1st field.
	printf("\n    Total Sum of %s: %d\n", last, total)
	printf("\nTotal Average of %s: %.2f\n", last, total / count)
}
last != substr($1, 1, 4) {
	# Perform the actions in this group when the 1st four characters in the
	# 1st field on this line is not the same as the 1st four characters in
	# the 1st field that we saw on the previous line.  Since there is no
	# previous line when we are reading the 1st line from our input file,
	# we also perform the actions in this group when processing the 1st
	# line in the input file.
	if(NR > 1) {
		# Perform these actions when we are not processing line #1.
		print_total()				# Print the total for
							# for the previous set.
		printf("\n=======================\n")	# Print a set separator.
	}
	# Save the 1st four characters from this line to compare against
	# subsequent input lines.
	last = substr($1, 1, 4)
	# Clear the count and total for this new set.
	count = total = 0
}
{	# Perform the actions in this group for every line in the input file.
	print		# Print the current input line.
	count++		# Increment the number of lines seen in this set.
	total += $2	# Add the contents of the 2nd field on this line to the
			# total for this set.
}
END {	# Perform the actions in this group after we have read the last line of
	# input from the input file.
	print_total()	# Print the total and average for the last set.
}' hhhh	# End the awk script and name the file to be processed.

Note that this just calculates the average when it is being printed instead of calculating averages every time a line is read and discarding that value except on the last line of a set.

ill try different combination...not working right

Don, my challenge now is putting date on total and averate. Putting a timestamp.. Trying every combination and googling..

------ Post updated at 11:34 AM ------

I modified it to
Code:
        printf("\n%s,%s,%d,total",  last, last, total)
        printf("\n%s,%s,%.1f,average\n",  last, last, total / count)

For parsing, but im hoping to have value like this
Code:
"date"baabbb4,baabbb4,101.95,total
"date"baabbb4,baabbb4,101.95,average

------ Post updated at 11:45 AM ------

I tried to add the line below

Code:
awk '
function print_total() {
        printf("\n%s,%s,%d,total", last, last, total)
        printf("\n%s,%s,%.1f,average\n", last, last, total / count)
        printf("%s", cmd)
}

#{ cmd = system("date") }
{ cmd = system("date  ") }

But when i put it in printf,,its throwing a lot of error..

        if(NR > 1) {

I found a way.. but ugly..
revise code:

The reason that is ugly, because, i have 100 entries in my for loop..they have the same time stamp, unlike if i will embed the date within the awk,,each line will have diffrent time by seconds or minutes..

You have a few problems. The date utility always terminates its output with a <newline>. The awk system() function sends its output to awk's standard output and returns the exit status of the command that you invoke. (It does not return the output produced by the command you invoke as a string that you can assign to a variable in awk as you tried to do in your code.)

To fix that, you can use sprintf() (in this case a couple of times) to create a date command string to give to system() that will invoke the date utility with a format string that will print the two lines of output you want each with the leading date and time field. Note that the following invokes date each time you call print_total() as in your earlier awk code:
Code:
function print_total() {
	dc = sprintf("date \"+%%a %%b %%d %%H:%%M%%S %%Z %%Y,%s-%s,%d,total%%n",
		last, last, total)
	dc = sprintf("%s%%a %%b %%d %%H:%%M%%S %%Z %%Y,%s-%s,%.1f,average\"",
		dc, last, last, total / count)
	system(dc)
}

If you just want to invoke date once at the start of your script and print that timestamp in all of the output produced by a single run of your awk script (which is closer to what you're doing now with awk and sed, but you're invoking date twice and may end up with one date and time on the total lines and a later date and time on the average lines), it would be much simpler to use:
Code:
awk -v dt="`date`" '
function print_total() {
	printf("%s,%s-%s,%d,total\n", dt, last, last, total)
	printf("%s,%s-%s,%.1f,average\n", dt, last, last, total / count)
}

PS I didn't see your last two updates before posting this. But, it should give you enough information to make changes to get what you want.

I did different code on the first block.. Nasty Ugly. Etc. But it worked. Hoping to clean that one. More cleane. I got the output right... But with an ugly code from me. Thank you for your help. But if by chance.. Can you make my code cleaner? Especially the for loop.

Code:
for i in `cat DATASERVER`;do  echo -n $i",";ssh $i "echo -n $i,|cut -c1-7 -n; f=\`/sbin/ip a|egrep '127.127|128.128' |head -1| awk '{print \$NF }' \` ; sar -n DEV|grep \$f|grep Average|awk '{print \$5 * 8 / 1000 \" Mbps\" }'"  ; done  |sed 'N;s/\n/, /' > rawdata.log



Code:
awk '
function print_total() {
        printf("\n%s,%s,%d,total", full, last, total)
        printf("\n%s,%s,%.1f,average\n", full, last, total / count)
 #       printf("%s", cmd)
}

#{ cmd = system("date") }

last != substr($1, 1, 7) {
        if(NR > 1) {
                print_total()
                printf("\n\n")
        }
        last = substr($1, 1, 7)
        full = substr($1, 1, 9) #added
        count = total = 0
}
{
        print
        count++
        total += $2
        full # added
}

END {   print_total()

}' rawdata.log |sed -e "s/.*nc.*/`date`,&/" > /datarate/datarate.log

Your desired output changes every time you add a new post to this thread.

I suggested code in post #11 that gets rid of the need to need for the for loop you showed us in post #12 and produces the results that loop would produce inside the print_total() function.

The code that I suggested there worked perfectly with the earlier sample data you provided to produce the output you said you wanted in an earlier post in this thread. If you modified that code to produce a different output format and introduced a syntax error in the code as you did it, I can't help you without seeing how you modified the code. Since your requirements are constantly changing and since you haven't provided us with any sample input that could possibly produce the most recent output you're showing us, I'm not motivated to try to rewrite my suggestion again hoping to guess at what your next output format requirements might be.
