Google Cloud Load Balancing

Overview

Google Cloud Load Balancing gives you the ability to distribute load-balanced compute resources in single or multiple regions, to meet your high availability requirements, to put your resources behind a single anycast IP and to scale your resources up or down with intelligent Autoscaling.

Use the Datadog Google Cloud Platform integration to collect metrics from Google Cloud Load Balancing.

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 HTTP Loadbalancer 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 HTTP Loadbalancer logs from Google Cloud Logging to the Pub/Sub topic:

  1. Go to the Google Cloud Logging page and filter the Google Cloud HTTP Loadbalancer 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.
