 Sentry SDK configuration options.
 
+**Example 1: Using `getGlobalContext()` for dynamic configuration**
+
 ```js
-// pages/+sentry.js
-// Environment: client, server
+// pages/+sentry.server.js
+// Environment: server
 
-// Shared configuration (client & server)
+import { getGlobalContext } from 'vike/server'

-  environment: globalContext.isProduction ? 'production' : 'development',
