      Proposing putting this in about.md under the "Operating system" section

      Name it "Available Processors"

      We should we able to query to runtime:
      Runtime.getRuntime().availableProcessors()

          We already have https://github.com/jenkinsci/support-core-plugin/blob/master/src/main/java/com/cloudbees/jenkins/support/impl/SystemConfiguration.java#L100

          Could be useful when Jenkins is running in docker (or a containerized platform such as k8s, mesos). Since the Runtime.getRuntime().availableProcessors() would reflect the CPU limit while nproc reflects the number of CPUs o the host.

          Reopening as the info pulled from /proc/cpuinfo seems to reflect the host. Which may not accurately reflect the allocated processes if running Jenkins in a container (Docker).

          I think it makes more sense to place this under the "Java" section https://github.com/jenkinsci/support-core-plugin/blob/a4b4c63641619602510966ce9821f3b434b3755d/src/main/java/com/cloudbees/jenkins/support/impl/AboutJenkins.java#L335 as we are looking at the Java Runtime.

          Naming it "Available CPUs:" to fit in with the existing formatting.
