Google Cloud TPU

Overview

Google Cloud TPU products make the benefits of Tensor Processing Units (TPUs) available through scalable and easy-to-use cloud computing resource for all ML researchers, ML engineers, developers, and data scientists running cutting-edge ML models.

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

Setup

Installation

To use Google Cloud TPU, you only need to set up the Google Cloud Platform integration.

Log collection

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

  1. Go to the Google Cloud Logging page and filter the Google Cloud TPU logs.
  2. Click Create Export and name the sink.
  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.
