Recently, I did a request in site24x7 to get total of request for determinated web site, for my surprise I get this totals:

- In sites24x7 i get 74 requests;

- In gtmetrix i get 174 requests.

So, my question is:

How site24x7 can get this confiability, like gtmetrix do? Or better, there's a way to site24x7 bring the same information?
