I guess after 4 years of Administration experience i know how to lie but this is different, I have used more than 10 tools but none of them giving exact bandwidth report on %. My manager is sharing this log information to head office and its not easy to lie when you are providing information to much much experience person working with head office.

If you have used some SNMP tools like PRTG, network monitoring and firewall analyzer you might know what information it gives you. If it was so easy i would have not posted here my friend.
