Overview

Google Cloud Pub/Sub brings the scalability, flexibility, and reliability of enterprise message-oriented middleware to the cloud.

Get metrics from Google Pub/Sub to:

  • Visualize the performance of your Pub/Sub topics and subscriptions.
  • Correlate the performance of your Pub/Sub topics and subscriptions 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.

Configuration

To collect custom Pub/Sub labels as tags, enable the cloud asset inventory permission.

Log collection

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

  1. Go to the Google Cloud Logging page and filter the Google Cloud Pub/Sub 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.

    Export Google Cloud Pub/Sub Logs to Pub Sub

  4. Click Create and wait for the confirmation message to show up.
