Throttle Concurrent Builds and Matrix configuration builds

[Geoffroy J]

Hello

i am trying to achieve the following use case using Throttle Concurrent Builds 2.2 plugin:

Given a multi-configuration (matrix) job, limit the parallel execution of the job configurations to the following:

1. no more than 4 configurations of given job running globally
2. no more than 2 configuratiosn of given job running per node

Job is configured to execute on a generic label matching several nodes.

However, at execution, i can see that all my node executors are being filled by the numerous matrix job configurations, so it seems above setup does not have any impact.

Am i missing something regarding this plugin usage?

Thanks in advance for your
