Output formatting .
below is a CPU utilization Log for ABC server.
However for every 15 minutes it generates 3 CPU values(with interval of 2 sec).
Code:
Host  CPU CPUtotal CPU% time
ABC 101.1 2 50.55 14 : 15
ABC 100.5 2 50.25 14 : 15
ABC 100.2 2 50.1 14 : 15
ABC 100.9 2 50.45 14 : 30
ABC 100.5 2 50.25 14 : 30
ABC 100.4 2 50.2 14 : 30
ABC 101.0 2 50.5 14 : 45
ABC 100.9 2 50.45 14 : 45
ABC 100.4 2 50.2 14 : 45
ABC 101.1 2 50.55 15 : 00
ABC 100.7 2 50.35 15 : 00
ABC 100.5 2 50.25 15 : 00
ABC 101.1 2 50.55 15 : 15
ABC 101.0 2 50.5 15 : 15
ABC 100.5 2 50.25 15 : 15
ABC 101.1 2 50.55 15 : 30
ABC 100.9 2 50.45 15 : 30
ABC 100.4 2 50.2 15 : 30
ABC 102.2 2 51.1 15 : 45
ABC 101.4 2 50.7 15 : 45
ABC 100.7 2 50.35 15 : 45

How would i list average value of cpu % at after every 15 minuates.
Say.
Code:
ABC 101.1 2 50 14 : 15
ABC 101.1 2 50 15 : 00
ABC 101.1 2 50 15 : 15
ABC 100.4 2 50 15 : 30
ABC 102.2 2 50 15 : 45

Please suggest .

I can generate the output like this but this is not what i expect.
Code:
$ awk '{sum+=$4; ++n; print $4 }; END { print "------"; print "Tot="sum"("n")";print "Avg="sum"/"n"="sum/n} ' cpu.txt
50.55
50.25
50.1
50.45
50.25
50.2
50.5
50.45
50.2
50.55
50.35
50.25
50.55
50.5
50.25
50.55
50.45
50.2
51.1
50.7
50.35
------
Tot=1058.75(21)
Avg=1058.75/21=50.4167

but i m expecting output in following format.



Code:
ABC 101.1 2 50 14 : 15
ABC 101.1 2 50 15 : 00
ABC 101.1 2 50 15 : 15
