This page describes what to do in case of an Icinga alert. For more information you could search the govuk-puppet repo for the source of the alert

App healthcheck failed

Every application on GOV.UK has a healthcheck endpoint. This is /healthcheck by default but can be overridden.

Icinga regularly checks the endpoint by making a GET request. If the endpoint doesn’t respond successfully, it triggers this alert.

To solve this issue, look at the logs of the application to see what is wrong.
