This sample demonstrates how to show all system environment metadata and properties on Google App Engine standard app.

• If you haven't already, Download and initialize the Cloud SDK

  gcloud init

• If you haven't already, Create an App Engine app within the current Google Cloud Project

  gcloud app create

• If you haven't already, Setup Application Default Credentials

  gcloud auth application-default login

• Copy the sample apps to your local machine:

  git clone https://github.com/GoogleCloudPlatform/java-docs-samples

• Add the appengine-simple-jetty-main Main class to your classpath:

  cd java-docs-samples/appengine-java11/appengine-simple-jetty-main
  mvn install

• Move into the appengine-java11/gaeinfo directory and compile the app:

  cd ../gaeinfo
  mvn package

• Deploy to App Engine standard environment using the following Maven command.

   mvn appengine:deploy -Dapp.deploy.projectId=<your-project-id>

• Direct your browser to https://<your-project-id>.appspot.com.
• View more in-depth metrics data on the StackDriver Monitoring Dashboard

Note: The first time the app is run (or after any metrics definitions have been deleted) it may take up to 5 minutes for the MetricDescriptors to sync with StackDriver before any results are shown. If you do not see results, please wait a few moments and try again.
