I would like know if ask about bandwidth consumption tracking does part content of community
Is the question directly related to security? That's the only test.
There are lots of questions where the answer can be applied to security, but those are not security questions.
For instance, suppose a firewall appliance is plugged into a faulty power outlet. Questions about how to fix the power outlet are off-topic.
If your question is about how to track bandwidth consumption because you want to use that information to calculate unauthorised use, this is off-topic. It's not a security question but a networking question that has a potential security application.
