  +#### `environments.[name].monitoring_urls`
  +At the end of a deplpoy, Lagoon will check this field for any URLs which you specify to add to the API for the purpose of monitoring. The default value for this field is the first route for a project. It is useful for adding specific paths of a project to the API, for consumption by a monitoring service. Please note, Lagoon does not provide any direct integration to a monitoring service, this just adds the URLs to the API. On amazee.io, we take the monitoring_urls and add them to our Statuscake account.

  ## Polysite
  In Lagoon, the same git repository can be added to multiple projects, creating what is called a Polysite. This allows you to run the same codebase but allow for different, isolated, databases and persistent files. In `.lagoon.yml` we currently only support specifying custom routes for a polysite project. The key difference from a standard project is that the `enviornments` becomes the second-level element, and the project name the top level.
