Code:
awk '
function print_total() {
        printf("\nTotal Sum of %s site is: %d Mbps\n ", last, total)
}
function print_average() {
        printf("\nTotal Sum of %s site is: %d Mbps\n ", last, average)
}

last != substr($1, 1, 7) {
        if(NR > 1) {
                print_total()
                printf("\n=======================\n")
        }
        last = substr($1, 1, 7)
        total = 0
        average = 0
}
{       print
        total += $2
        average total/NR
}
END {   print_total()
        print_average()
}' hhhh > datarate.log
cat datarate.log

trying different combination but to no avail. Thank you

ctlstat

CTLSTAT(8)						    BSD System Manager's Manual 						CTLSTAT(8)

NAME

     ctlstat -- CAM Target Layer statistics utility

SYNOPSIS

     ctlstat [-t] [-c count] [-C] [-d] [-D] [-j] [-l lun] [-n numdevs] [-w wait]

DESCRIPTION

     The ctlstat utility provides statistics information for the CAM Target Layer.  The first display (except for dump and JSON modes) shows aver-
     age statistics since system startup.  Subsequent displays show average statistics during the measurement interval.

     The options are as follows:

     -t 	 Total mode.  This displays separate columns with the total CTL read and write output, and a combined total column that also
		 includes non I/O operations.

     -c count	 Display statistics this many times.

     -C 	 Disable display of CPU statistics.

     -d 	 Display DMA operation time (latency) instead of overall I/O time (latency).

     -D 	 Text dump mode.  Dump all available statistics every 30 seconds in a text format suitable for parsing.  No statistics are com-
		 puted in this mode, only raw numbers are displayed.

     -h 	 Suppress display of the header.

     -j 	 JSON dump mode.  Dump all available statistics every 30 seconds in JavaScript Object Notation (JSON) format.  No statistics are
		 computed in this mode, only raw numbers are displayed.

     -l lun	 Request statistics for the specified LUN.  This option is incompatible with total (-t) mode.

     -n numdevs  Display statistics for this many devices.

     -w wait	 Wait this many seconds in between displays.  If this option is not specified, ctlstat defaults to a 1 second interval.

EXAMPLES

	   ctlstat -t

     Display total statistics for the system with a one second interval.

	   ctlstat -d -l 5 -C

     Display average DMA time for LUN 5 and omit CPU utilization.

	   ctlstat -n 7 -w 10

     Display statistics for the first 7 LUNs, and display average statistics every 10 seconds.
