Azure Budget Alert Anomalies: Invalid Forecasted Date and Missing Data in Fields

Question

Azure Budget Alert Anomalies: Invalid Forecasted Date and Missing Data in Fields

Andrii Lytvynenko 20

I've received an unusual Azure Budget Alert on June 1, 2025, via a custom webhook endpoint configured in an Action Group, using the non-common alert schema (AIP Budget Notification). The alert payload contains multiple anomalies:

ForecastedDate is set to January 01, 0001, appearing to be the default .NET minimum date.
ForecastedAmount and ForecastedPercentage fields are completely empty.
ForecastedTotalForPeriod shows a valid value of 680.31 €, with the alert triggered based on a forecast threshold of 643.50 €.

It seems possible that the forecast data was only partially populated, potentially due to timing issues at the beginning of the billing cycle.

Has this issue been previously reported? Is there a known workaround? Any insights or official guidance would be appreciated.

1.Monitor the alert behavior over the next few days to determine if the forecast fields populate correctly in subsequent alerts.

Hi Vinod Pittala,
Yeah, that seems to be an issue only with first budget alerts at the start of the billing period. Subsequent alerts are generated normally.

Hello Andrii Lytvynenko,

The behavior you're observing appears to be related to timing issues at the start of the billing cycle, during which forecast data may not yet be fully populated when the alert is triggered. As a result, certain fields in the payload—such as ForecastedDate, ForecastedAmount, and ForecastedPercentage—may remain unset or default to placeholder values.

As there is currently no official Microsoft documentation or confirmed workaround addressing this specific issue, I recommend the following steps:

Monitor the alert behavior over the next few days to determine if the forecast fields populate correctly in subsequent alerts.
Consider switching to the Common Alert Schema, which may provide more consistent payload formatting and improved support.
If the issue persists or impacts your automation workflows, I suggest raising a support request with Microsoft Azure for further investigation and visibility. You can create a support request using the following link:https://portal.azure.com/#view/Microsoft_Azure_Support/HelpAndSupportBlade/~/overview

Please let me know if you need any further assistance regarding this issue—I'm here to help.

let us know if any help, we will always help as you needed.!
