In Admin Menu>Monitoring>Background Jobs>Sidekiq stats not shown

Summary

The problem is exactly the same as shown in issue #23825 (closed) I got asked to open a new report for OpenBSD. My environment is OpenBSD 6.1-beta amd64.

Steps to reproduce

in Admin Menu>Monitoring>Background Jobs>Sidekiq stats are not shown, Looks exactly the same for me as in the screenshot shown in issue #23825 (closed) https://gitlab.com/gitlab-org/gitlab-ce/uploads/11973afe7f36791a5b5eca56bb7afc22/Gitlab.JPG

What is the current bug behavior?

The sidekiq stats are not shown.

What is the expected correct behavior?

The sidekiq stats should be shown.

also posted in the other issue, following ps command produces output for me:

ps -U _gitlab -o pid,pcpu,pmem,stat,start,command | grep sidekiq 49258 0.2 2.3 S Fri10PM ruby23: sidekiq 4.2.7 gitlab [0 of 25 busy] (ruby23) 58482 0.0 0.0 Ip Fri10PM -sh -c cd /var/www/gitlab/gitlab && \t\tbundle23 exec sidekiq -C /etc/gitlab/sidekiq_queues.yml - 67788 0.0 0.0 R+/0 10:49PM grep sidekiq

the following doesn't produce any output: ps a -o pid,pcpu,pmem,stat,start,command | grep side
