We are very excited to introduce the new Azure Data Explorer samples gallery feature. This provides an easy way to upskill and demo Azure Data Explorer with an end-to-end experience on a free, publicly available cluster known by the name of a ‘help’ cluster.
There is no need to ingest data or create a cluster, it's all done for you with the pre-loaded sample datasets. To learn, you just need to follow the tutorial, analyze data by executing provided sample queries, follow KQL commands to alter policies and explore parameterized dashboards.
To access the ‘help’ cluster, you need either an Azure active directory (AAD) user identity or a Microsoft account (MSA).
The samples gallery comprises of sample datasets with guided tutorials in the form of commonly used queries along with the detailed description and sample dashboards. You can navigate to the samples gallery from home page -
Following is a high-level view of the components in the samples gallery -
To get started with Azure Data Explorer, you can either read through the documentation and learn by trial and error, or you can use these samples to guide you through, as shown in the following 3 steps.
Step 1 - Pick a sample dataset - Logs, Metrics, IoT, or Basic from the home page
Step 2 - Follow the tutorial on each of these datasets to understand what you can achieve with this type of data. For example, the ‘SampleMetrics’ tutorial covers the following scenarios:
A summary of above scenario's data flow is shown in the following diagram -
Step 3 - Explore a sample dashboard. There are 4 sample dashboards created on top of the sample datasets that will give you a fair idea on how easy it is to build dashboards with natively supported visuals and parameters to slice and dice data. When you select any of the sample dashboard, a copy of the dashboard will be generated for you to try -
Just to give you a flavor of another dataset, lets try creating 'Sample Logs Dashboard' -
This is just a beginning, we will continue adding more datasets based on your feedback so please share your ideas here.
Enjoy learning!
