title: View all labels in Jenkins
body: <p>Is there a easy way to get a list of all node labels in Jenkins?</p>
  
  <p>I can see which labels are set on each node (.../computer/) and which nodes have the same label (.../label/). But similar to listing all nodes on .../computer/ there is no listing of all the labels on .../label/</p>
  
  <p>The approach with <a href="https://stackoverflow.com/questions/14531919/node-labels-from-jenkins-api">python and jenkinsapi</a> or similar seem a bit too advanced for a listing that probably already is available in Jenkins (but not visible?)</p>
