Traffic pattern for last one year in my organization

[PrabhakarReddy]

I want to understand how much traffic flow is there in my organization on hourly bases from last one year. Is there any management call available which able to provide hourly traffic for last one year.

There is not a single management call. 

You will want to perform a series of them.

This tool, the API Traffic Summarizer, might help.
