Beginning with upgrade to 2.289.1.2 we noticed that loadStatistics for labels and agents is now borked.
E.g. /label/VALIDLABEL/load-statistics shows a broken icon for the statistics, while
Shows an OOPS demon jenkins with an error.
However `label/VALIDLABEL/api/python?pretty=true&depth=3` does provide the expected values.
See attached screenshots.
We also recently removed several plugins as suggested by the Jenkins Health Advisor (tables-to-div issues as well as obsolete plugins).
We make use of these statistics to help understand loads on our agents - usually by LABEL.
Load-statistics are similarly broken for agents, too, e.g.
`/computer/VALIDAGENTNAME/load-statistics` is similarly broken.
Since we had recently upgraded the monitoring plugin, we downgraded that and restarted but no help there.
