Action required: Migrate to using ARG query for “Get Alert Summary” in Azure Monitor

You’re receiving this email because you’re using GetAlertSummary API in Azure Monitor. 

On 30-Sep-2026, we will retire GetAlertSummary API. Before that date, you’ll need to migrate to ARG query, which provides all of the functionality of GetAlertSummary API plus new ones, including: 

• Ability to add new fields to the query that returns the alert summary.  

• Ability to be more flexible in the query that returns the alert summary. 

Required action 

 To avoid a breaking change in your system while using GetAlertSummary API, use the migration path to start using Arg query by 30-Sep-2026.
