### Problem This is an action item after the mitigated incident - . To avoid such incidents in the future, we need to validate structured log messages against the [ES index schema](https://gitlab.com/gitlab-com/runbooks/-/blob/master/elastic/managed-objects/lib/index_mappings/rails.jsonnet?ref_type=heads). We could implement that in the CustomersDot and extract the implementation later to the [`labkit-ruby` gem](https://gitlab.com/gitlab-org/ruby/gems/labkit-ruby) to make this functionality available to everyone in GitLab. ### Proposal TBD
