fix(alerts): remove LoggingVisibilityDiminished
What
Delete the LoggingVisibilityDiminished
alert.
Why
Looking at the last 5 incidents:
- gitlab-com/gl-infra/production#15969 (closed)
- gitlab-com/gl-infra/production#15942 (closed)
- gitlab-com/gl-infra/production#15825 (closed)
- gitlab-com/gl-infra/production#14543 (closed)
- gitlab-com/gl-infra/production#14407 (closed)
For all of them, the EOC just had to wait and do no action, sometimes even silencing the alert. At the moment this alert is unactionable and has no customer-facing impact. The only impact is engineers at GitLab Inc. seeing delayed logs, but the on-call doesn't do anything.
There is https://gitlab.com/gitlab-com/gl-infra/reliability/-/issues/16480 to investigate the issue and see if we can implement something. We can always add this after if we fix the scaling issues.
