Write queries and create dashboards using the full power of Azure Resource Graph

The Azure Resource Graph

Sometimes, it is difficult to gain insights into your cloud resources. Especially when they are scattered across many Azure subscriptions. Azure Resource Graph provides a solution for this. You can use it to query your resources in Azure across subscriptions. Azure Resource Graph is an API that you can use as a REST API, from the Azure portal or from the Azure CLI, Azure PowerShell, and Azure SDK for .NET.

You can do many things with the Azure Resource Graph, like searching for resources that expose IP addresses, or returning all VMs that run Linux. In this post, we'll explore how you can use the Azure Resource Graph from the Azure portal and how you can integrate its results in Azure portal dashboards.

Prerequisites

If you want to follow along, you'll need the following:

  • An Azure subscription (If you don't have an Azure subscription, create a free account before you begin)

Azure Resource Graph Queries are first-class citizens in the new Azure portal

Let's explore how we can use Azure Resource Graph in the Azure portal.

  1. Go to the Azure portal
  2. In the search bar at the top, search for Azure Resource Graph.
    • This brings up the Resource Graph Explorer. By the way, have you noticed that the results from the search bar also show links to documentation for the search results and other helpful resources?
    • Click on the Resource Graph Explorer to open it

You are now in the Resource Graph Explorer. From here, you can run Azure Resource Graph queries. You create these queries with the Kusto Query Language (KQL), which you also use to query Application Insights and Azure Monitor.

On the left side of the Resource Graph explorer, you'll find the resources panel. You can browse through it to find out which resource types and objects you can query.

Let's run some queries.

  1. In the query editor of Azure Resource Graph, type the following query:
count
1
  1. Click Run query to execute the query. This returns the total number of resources in Azure
  2. Let's make it more interesting. Change the query to the following:
summarize Count=count() by type
1
  1. Click Run query to execute the query. This returns the number of resources in Azure, grouped by type of resource
  2. In the results window, navigate to the Charts tab
  3. Click Bar Chart. This generates an interactive bar chart from the results. That was easy, wasn't it?

  1. Let's expand on the query to order the results. Change the query into:
summarize Count=count() by type
| order by Count desc
1
2
  1. Click Run query to execute the query. The results are now ordered by the amount of resources
  2. Let's make a final change to the query to show something else:
summarize Count=count() by type, location
| order by Count desc
1
2
  1. Click Run query to execute the query. The results now show the amount of resources and their location
  2. In the results window, click the Pin to dashboard button, next to the Bar Chart drop-down. This pins the chart to the dashboard in the portal
  3. Now go to the dashboard in the Azure portal. Here, you can see the interactive chart
  4. There is now a new filter built into the Azure portal dashboards. This allows you to create a filter that filters the resources that you see in your Azure Resource Graph results. Create a filter for Location, that filters on a specific location in which you have resources running. This changes the chart. That is pretty cool!

Conclusion

Azure Resource Graph is a very powerful service in Azure that enables you to get insights into your resources. And now, it is a first-class citizen in the Azure portal. You can pin results to Azure portal dashboards and even create interactive charts from them, just by selecting a chart as the format of the result. And you can also create filters in your Azure portal dashboard that filter the results of the Resource Graph queries. This is really powerful. Go and check it out!
