Azure Data Explorer – Setting up a Cluster

,

I’ve worked with Log Analytics quite a bit over the years and that’s taken me down the road of the Kusto Query Language – or KQL

So, using Azure Data Explorer Clusters seemed the next logical step on that journey.

Log Analytics is great for storing and querying diagnostic data from Azure (or any other infrastructure) – but I decided that I might want to investigate my own data.

So, with that in mind – I decided to set up my own Azure Data Explorer Cluster and start looking around.

It’s easy enough to find in the Azure Portal – I chose to favorite it as I expect to be using it a fair bit over the next little while

Find “Azure Data Explorer Clusters” via the Azure Portal search bar

You can also get to it via a shortcut

Select “Azure Data Explorer Clusters” – optionally favorite

Next, I select “Create” and then filled in the minimum amount of information needed to get up and running.

Information for our ADX cluster

Just a few things to focus on here – firstly, the combination of the cluster name and the region is going to form part of a URI – so this has to be unique, and there are certain formats that the name has to meet, but you’ll soon know if you have not met them as the screen will call them out instantly.

Additionally, I’m just creating a Dev cluster here – note that there is no SLA.

Also, the region that I chose has Availability Zones – yours might not, or you might choose not to take advantage of them. I chose to include all three.

Availability Zones

You’ll then notice that you can step through all of the remain setup.

Additional setup (can be skipped – I accepted the defaults)

I simply accepted the defaults, but it’s great to know you can define additional settings at this stage.

It’ll take a little time to set the cluster up – but you’ll soon be up and running.

And once we are up and running we can see that the URI is made up of the cluster name and region

ADX Cluster name

In order to create a database on the cluster head to the resource, click on “Databases” in the left hand side menu (scrolling may be needed), click “Add database” near the top of the screen and then enter a name for the database in the fly-out pane.

Create a new database on out ADX cluster

That’s it – we now have our first Azure Data Explorer Cluster created with a new shiny database.

Hope this help somebody.

Cheers

Marty.
