Finally, the code will disable concurrent builds on a per branch basis. The second You have to manage restrictions with the tools that Jenkins provides. Throttling settings can be applied both globally or per agent, so we can limit the number of certain jobs that each agent individually can run at a time without limiting the number of executors for un-throttled jobs.

To this Jenkins, I attached 3 slave nodes. In addition to the original limit reques: total number of concurrent builds (the original request), I would like to see an additional limit: total number of concurrent builds per slave.
