Debugging GitLab Workhorse

As workhorse is a Golang written application, you can use methods for this language to debug programs.

It also supports remote error logging with Sentry. To activate this feature, set the GITLAB_WORKHORSE_SENTRY_DSN environment variable.

For Omnibus installations

The following is defined in the file (/etc/gitlab/gitlab.rb):

gitlab_workhorse['env'] = {'GITLAB_WORKHORSE_SENTRY_DSN' => 'https://foobar'}

For Source installations

The following environment variable can be set in the file (/etc/default/gitlab):

export GITLAB_WORKHORSE_SENTRY_DSN='https://foobar'
