Amazing work and kudos for the focus and drill down. This is something that I have been researching from another angle around the social nets for years. I will be following so keep us in the loop. This is a very important concept that will change the game on many things.

No, it would be the size in bytes of the SQL Query and the response which would be the response to the SQL Query. You can try just averaging the queries or adding the queries and responses together, then averaging this size over time per second to get bytes per second.

Hopefully that helps. There is a deeper view of Data Gravity and its relationships that I intend to publish soon, FYI.

hello again dave, I would like to ask something about the average request size..
for example, I have an application connecting to a database server that uses mysql, is the average request size the size of mysql packet? thanks

A proxy and/or a cache with counters, or use an Apache Mod and logs. Those would be two decent routes IMO.

Thanks..! Okay, so let’s just say that the application is a web application. What would you recommend to dynamically get the values for bandwidth, average request size and latency? I have tried some methods like using javascript files to get the results but I would like to know if you have better ideas on how to do that.

Yes, that’s correct, assuming that the application isn’t the end user’s desktop. If it is an end user’s desktop, I would recommend measuring the aggregate requests and response time at the webserver (just to make it easier).

I see your point… so the average request size, bandwidth, and latency would be the coming from all the instance of an application, right?
because, each request may come from different locations but uses the same application… Therefore, the ave request size, bandwidth and latency should be the average of all values taken from each of those individual requests from different locations….

Because the requests per second represent the attraction to the Data itself. If I need the Data from a mass, I must request it, each request represents need or an amount of gravity.

Good day dave, I have a question…
Why do you have to multiply the application mass and data mass by ‘number of request per second’?
according to the general formula for gravity, you only need to multiply the two masses involved.. thanks. . . .

Good day dave, I have sent you a copy of my paper. . .Remember me? Now I will start the actual work on the project. . It would be nice if you could give me some advice and comments. . thanks. .
