Public Preview: Simple Log Alerts in Azure Monitor

We are excited to announce the Public Preview of Simple Log Alerts in Azure Monitor, available starting in mid-May. This new feature is designed to provide a simplified and more intuitive experience for monitoring and alerting, enhancing your ability to detect and respond to issues in near real-time.

Simple Log Alerts are a new type of Log Search Alerts in Azure Monitor, designed to provide a simpler and faster alternative to Log Search Alerts. Unlike Log Search Alerts that aggregate rows over a defined period, Simple Log Alerts evaluate each row individually.

This feature is now available for customers using Basic Logs who want to enable alerting. Previously, when customers opted to configure the traces table in Azure Monitor Application Insights as Basic Logs for cost optimization, they were unable to create alerts on that data. With the introduction of Simple Log Alerts, customers can now continue to benefit from cost savings while still setting up alerts on telemetry from Basic Logs.

Key Benefits

🔍 Simplified Query Language

Unlike Log Search Alerts that use complex queries with aggregations and joins, Simple Log Alerts use the transform Kusto Query Language (KQL).

Low Latency Alerting

By evaluating each row individually, Simple Log Alerts provide faster alerting compared to Log Search Alerts. This means that alerts are triggered in near real-time, allowing for quicker incident response.

🌐 Broad Applicability

Simple Log Alerts support multiple log tiers, including Analytics and Basic Logs, which previously did not have any alerting solution.

💰 Pricing Information

The pricing for Simple Log Alerts is based on one-minute alerting and is the same as traditional log alerts. For detailed pricing information, please refer to the https://learn.microsoft.com/azure/azure-monitor/alerts/alerts-create-rule-cli-powershell-arm.
