title: Upgraded nginx, now munin stats don't work
body: <p>I was running Debian 8 and the default repo's version of nginx (~1.6). I changed the repo to the nginx one and downloaded the latest version (1.10.0) and now my munin stats don't work, except for the RAM usage. Specifically;</p>
  
  <p>Requests
  Requests/connection handled
  Nginx status</p>
  
  <p>...all don't work and produce blank graphs. Nginx works as expected and nothing else appears to have changed. I'm not sure what logs to check - munin-graph.log, munin-html.log, munin-update.log and munin-node.log contain no errors or warnings.</p>
  
  <p>Any advice of how to troubleshoot this is welcome!</p>
