title: How to know the network bandwidth used at a given time?
body: <p>I'm trying to build a load balancer for a program that is running in 2 different servers.</p>
  
  <p>So far my load balancer, only checks the CPU usage of each server using an instance of PerformanceCounter in each server program.</p>
  
  <p>I would also like to check the bandwidth usage of each server, how can I check that?</p>
  
  <p>(it is probably done also using the PerformanceCounter but I'm unfamiliar with its usage)</p>
