The jekins monitoring agent would display the following (relative url: /monitoring/nodes?period=jour):
!image-2022-10-05-14-19-47-200.png! While the server dashboard (releative url /) would display something like (which is correct): !image-2022-10-05-14-24-13-696.png! We would like to have something monitoring the Build Queue size as showing in monitoring. Currently, monitoring jenkins agents "build queue length" does not reflect the build queue length on the dashboard, which is verifiably correct because the jobs on the queue is listed right below. |

The dashboard is verifiably correct because the jobs on the queue are listed. |

The monitoring plugin will now use Jenkins.getInstance().getQueue().getItems().length instead of Jenkins.getInstance().getQueue().getBuildableItems().size().

In the monitoring plugin, the NodesCollector class uses Jenkins.getInstance().getQueue().getBuildableItems().size(), including buildable and pending items. The monitoring plugin currently counts the items in queue like the Load Statistics in the /manage/load-statistics page.
While the UI probably uses Jenkins.getInstance().getQueue().getItems().length including blocked and waiting items.
The difference you see is probably the blocked items count.
