Google Cloud Functions

Overview

Google Cloud Functions is a lightweight, event-based, asynchronous compute solution that allows you to create small, single-purpose functions.

Get metrics from Google Functions to:

  • Visualize the performance of your Functions.
  • Correlate the performance of your Functions with your applications.

Setup

Metric collection

Installation

If you haven’t already, set up the Google Cloud Platform integration first. There are no other installation steps.

Log collection

Google Cloud Function logs are collected with Google Cloud Logging and sent to a Dataflow job through a Cloud Pub/Sub topic. If you haven’t already, set up logging with the Datadog Dataflow template.

Once this is done, export your Google Cloud Function logs from Google Cloud Logging to the Pub/Sub topic:

  1. Go to the Google Cloud Logging page and filter the Google Cloud Function logs.
  2. Click Create Sink and name the sink accordingly.
  3. Choose “Cloud Pub/Sub” as the destination and select the Pub/Sub topic that was created for that purpose. Note: The Pub/Sub topic can be located in a different project.
  4. Click Create and wait for the confirmation message to show up.
