[root@centos7-katello-client tracer]# tracer -e
You should restart:
  * Some applications using:
      sudo systemctl restart sshd
      sudo systemctl restart tuned

  * These applications manually:
      dhclient
      master
      pickup
      python
      qmgr
[root@centos7-katello-client tracer]# systemctl restart NetworkManager
[root@centos7-katello-client tracer]# tracer -e
