It would be helpful to se per node what jobs will (excussively) and mybe could (by tag) ron on this node.
I think that page is quite close, except that the report is about the node's index page (/computer/foo), not a label. May be sufficient to add a node's self label to that page (it's missing currently, only explicitly assigned labels are shown).
I assigned this one to me. I'm adding (in Label Linked Jobs Plugin) an Action for each computer to see this kind of data. This is very similar to what was already done in the plugin.
See attached screenshot for proposed new page that would meet requirements.
Code changed in jenkins
New linked jobs page for nodes, for JENKINS-20035
Made new page more detailed, grouping jobs by labels. I think I'm pretty much done, just need to release new version of plugin with this new Node Action/page.
