Azure Advisor Cost Augmented Data Stopped Updating

[sainathyv]

Hi Team,

We noticed that the "Advisor Cost Augmented" file was successfully retrieving data until May 12, 2026. Starting after that date, the file is being generated with 0 bytes, and no data is available.

We have not made any changes on our end that could have caused this issue. The data retrieval appears to have stopped unexpectedly.

Could you please help us investigate the following?

• Is there any known issue or recent change in Azure Advisor that could affect this data?
• Were there any changes to the Advisor API, data source, schema, permissions, or authentication after May 12, 2026?
• Is there a recommended way to debug or troubleshoot why the file is now returning 0 bytes?
• Are there any additional logs, API responses, or configuration settings we should check?

File Path

src/optimization-engine/runbooks/recommendations/Recommend-AdvisorCostAugmentedToBlobStorage.ps1

Any guidance on troubleshooting this issue or identifying potential changes on the Azure Advisor side would be greatly appreciated.

Thank you!

Hi Hélder Pinto (@helderpinto)
Could you please help me here!

sainathyv, follow these troubleshooting steps:

1. Check whether the Export-AdvisorRecommendationsToBlobStorage runbook has been running successfully in the past weeks. In case it is failing, look for the error message in the Exception tab of the latest job.
2. In case the runbook above is executing correctly, check whether the AzureOptimizationAdvisorV1_CL Log Analytics table has been ingesting any data in the past weeks. Run the following query: AzureOptimizationAdvisorV1_CL | where TimeGenerated > ago(14d) | count
3. In case the query above returns 0 results, check whether there are instances of the Ingest-OptimizationCSVExportsToLogAnalytics runbook failing in the past weeks where the StorageSinkContainer parameter is advisorexports. In case it is failing, look for the error message in the Exception tab of the latest job.
