Hi K H Q
You can set up custom alert rules based on the metrics and logs collected from your Azure VMs. These include alerts for:
CPU Usage
Memory Utilization
Disk I/O
Network traffic
Azure Monitor also offers a set of recommended alert rules that you can quickly enable. These cover common scenarios like VM availability, boot failures, and connectivity issues, and are a great starting point for comprehensive monitoring.
Azure Monitor supports several types of alerts:
Metric Alerts: Triggered when a monitored metric (e.g., CPU usage) crosses a defined threshold.
Log Alerts: Use Log Analytics queries to evaluate log data and detect anomalies or patterns.
Activity Log Alerts: Triggered by specific changes or events (e.g., VM stop/start) recorded in the Azure Activity Log.
To simplify management and scale your alerting setup, you can create multi-resource alert rules. These can target all VMs within a resource group or subscription in the same region saving time and effort.
While alerting is a powerful tool, it's important to note that some types of alerts may incur costs. Charges are typically based on the type of rule and how frequently it's evaluated. Be sure to review Azure Monitor pricing https://azure.microsoft.com/en-us/pricing/details/monitor/ for details.
