We are excited to announce the General Availability of Simple log alerts in Azure Monitor! This feature is designed to provide a simplified and more intuitive experience for monitoring and alerting, enhancing your ability to detect and respond to problems in near real-time.
Simple log alerts are a type of Log search alerts in Azure Monitor, designed to provide a simpler alternative to traditional Log search alerts. Unlike Log search alerts that aggregate rows over a defined period, Simple Log Alerts evaluate each row individually.
Simple Log Alerts are supported using Basic logs as well. Before, choosing Basic logs for cost optimization - for example, configuring the traces table in Application Insights with Basic logs plan - meant giving up the ability to alert on that data. Simple log alerts close that gap, so you can keep the cost savings and alert on telemetry stored in Basic Logs.
š When to use
Simple Log Alerts are ideal for monitoring applications or network traffic where unaggregated, real-time detection and quick incident response are critical.
Example scenarios:
- Failed automation jobs - get notified the moment a backup job, scheduled task, or any automated process fails, rather than waiting for an aggregation window.
-
Windows events affecting storage or security - alert on individual event log entries that signal disk failures, security breaches, or service disruptions.
š Flexible Trigger Recurrence
By default, Simple log alerts fire on every matching row, but you can tune this to reduce noise. Choose to alert only when the condition is met at least once, twice, three times, or a custom number of times within a minute - giving you control over sensitivity without sacrificing the low-latency.
š° Pricing Information
Simple log alert rules evaluate your data every minute, so billing is the same as 1-minute frequency alert rules. For detailed pricing information, refer to Pricing - Azure Monitor | Microsoft Azure. You will see these rules in your billing statement tagged with kind:simplelogalert.
