title: How to see that Jenkins polled a Git repo
body: <p>I know getting jenkins to poll a git repo is not best practise but I have to do it now as I do not have access to the git server. </p>
  
  <p>My understanding is the build job will only happen if there are any changes. So if you have configured to poll every 5 mins, the build will only happen if there is a change so you could be waiting an hour to see something.</p>
  
  <p>I'd still like to have confidence that jenkins has polled the git server and just been told there are no changes.  </p>
  
  <p>Can I see this anywhere?</p>
  
  <p>Thanks</p>
