title: What is the meaning of the "Load" column in Apache balancer-manager?
body: <p>I've set up the Apache (2.4) load-balancer which is working okay. To monitor its performance, I enabled the balancer-manager handler, which shows the status of the balancers.</p>
  
  <p>I noticed a "Load" column, which was not present in version 2.2, with a value that may be negative, but I don't understand its meaning nor I was able to find documentation relative to this.</p>

  <p>Can anyone explain the meaning of that value or point me to the right documentation?</p>
