There is no data in Log Analytics Demo, Please help!

Whilst working through the AZ-104 - Analyse your Azure infrastructure by using Azure Monitor Log Unit 4 module, I found I was not able to return any data. Searching for an answer didn't provide any answers.

Figured out it was due to the logged events were not in the specified time range (<24 Hours). Changing Time Range to Custom and setting it to several months ago resolved the issue

Date Range set between 2025-01-01 to 2025-05-08

Now the example query in the Exercise works

note: you will also need to adjust any Time filters specified in the query to accommodate the available data.

Greetings & Welcome to Microsoft Q&A forum! Thanks for posting your query!

It seems like you are facing an issue where there are no logs showing up in your Log Analytics workspace, which could be impacting your ability to train and practice with Kusto Query Language (KQL). To help with the query and any potential issues you're encountering, here are some general troubleshooting guide and explanation.

Check Resource Providers - Ensure that the necessary resource providers are registered for your Azure subscription. For Log Analytics to work correctly, the Microsoft.OperationalInsights resource provider must be registered, along with any other resource providers depending on the data sources you're using (e.g., Microsoft.Compute for VM data, Microsoft.Security for Security Center data). This is the core provider for Azure Log Analytics and is essential for creating and using Log Analytics workspaces. Once the relevant resource providers are registered, try querying the Log Analytics workspace again.

Verify Data Ingestion - Double-check that logs are actually being ingested into the workspace. You might want to check the configuration of the data sources you're using and ensure that data is flowing into Log Analytics.

Check if Sample Data is Loaded - Sometimes, demo environments may require specific steps to load sample data. You can check if there's an option or instruction within the demo environment to load or refresh the sample data.

Select the Correct Workspace - Ensure that you're querying the right Log Analytics workspace. If you have multiple workspaces or environments, it’s important to verify that you’ve selected the correct one where the data is supposed to be.

I hope this information helps. Please do let us know if you have any further queries.
