The monitoring section offers interesting bits of information that are needed so that you can administer your GitLab instance:
- System information: CPU, memory, and other metrics.
- Background Jobs: GitLab integrated the Sidekiq statistics gem into the application, and it can be viewed here.
- Logs: In this section, you can view 2,000 lines of information from the most important GitLab log files (unicorn, gitlab-shell, Sidekiq, and so on).
- Health check: This is a very interesting page for sysadmins. Here, you will find endpoints that will give some insight into the health of the running GitLab instance. There is also a token present, which you will need to send as a parameter if your monitoring software wants to scrape the page.
