Tutorial: Set up an Azure Time Series Insights Gen2 environment

Note

The Time Series Insights service will be retired on 7 July 2024. Consider migrating existing environments to alternative solutions as soon as possible. For more information on the deprecation and migration, visit our documentation.

This tutorial guides you through the process of creating an Azure Time Series Insights Gen2 pay-as-you-go (PAYG) environment.

In this tutorial, you learn how to:

• Create an Azure Time Series Insights Gen2 environment.
• Connect the Azure Time Series Insights Gen2 environment to an IoT Hub.
• Run a solution accelerator sample to stream data into the Azure Time Series Insights Gen2 environment.
• Perform basic analysis on the data.
• Define a Time Series Model type and hierarchy, and associate it with your instances.

Tip

IoT solution accelerators provide enterprise-grade preconfigured solutions that you can use to accelerate the development of custom IoT solutions.

Sign up for a free Azure subscription if you don't already have one.

Prerequisites

• At minimum, you must have the Contributor role for the Azure subscription. For more information, read Assign Azure roles using the Azure portal.

• Create an environment using either the Azure portal or CLI.

Create a device simulation

In this section, you will create three simulated devices that send data to an Azure IoT Hub instance.

1. Go to the Azure IoT solution accelerators page. Sign in by using your Azure account, then select Device Simulation.

   

2. Scroll down to read the Overview and Getting started sections.

3. Follow the deployment instructions in the Getting Started section.

   It may take up to 20 minutes to complete this process.

4. When deployment has finished, you'll be provided the URL to your simulation. Keep this page open because you'll return to it later.

   Important

   Don't enter your solution accelerator yet! Keep this web page open because you'll return to it later.

   

5. Now, inspect the newly created resources in the Azure portal. On the Resource groups page, notice that a new resource group was created by using the solutionName you provided in your ARM template parameters file. Make note of the resources that were created for the device simulation.

   

Create an Azure Time Series Insights Gen2 environment
