 * Are sending both staging and production APM data to an {{es}} cluster.
-* Have configured the `environment` variable in your APM agent configurations. This variable sets the `service.environment` field in APM documents. You should have documents where `service.environment: production` and `service.environment: staging`. If this field is empty, see [service environment filter](filter-application-data.md#environment-selector) to learn how to set this value.

+Global filters are ways you can filter your APM data based on a specific time range or environment. When viewing a specific service, the filter persists as you move between tabs.

+The environment selector is a global filter for `service.environment`. It allows you to view only relevant data and is especially useful for separating development from production environments. By default, all environments are displayed. If there are no environment options, you’ll see "not defined".

+Service environments are defined when configuring your APM agents. It’s vital to be consistent when naming environments in your APM agents. To learn how to configure service environments, see the specific APM agent documentation:
