This is a simple probe for measuring sources of HTTP connection latency, including DNS lookup, TLS handshake, connection establishment, and data transfer.
Enable the Stackdriver and Kubernetes Engine APIs in the Cloud Console. You will need to enable Stackdriver premium for use of custom metrics.

As the Google Cloud Functions (GCF) ecosystem develops there are many useful examples of functions becoming available. However, it is still kind of hard to lock down the HTTP functions. For example, you may want to add authentication and protect the functions from attacks from the open Internet. On the other hand, Google Cloud Endpoints have been around for a little longer and designed specifically for HTTP access.
