Set up alarms to be notified when your Azure resources exceed defined thresholds. Alarms can be configured at a group level or directly on individual monitored resources.
Cloudmon alarm rules work on a trigger model. You define a condition (the IF) and an action (the THEN). When the condition is met for the specified number of consecutive intervals, Cloudmon fires the alarm and executes the configured actions, such as sending a notification or running a script.
There are two ways to configure alarm rules for Azure resources:
Each alarm is built around a simple IF/THEN model, where you select a metric, set a threshold, and define what happens when it is breached. Learn more.
Below are recommended alarm configurations for the most common Azure monitoring scenarios:
| Use Case | Metric | Suggested Threshold | Why |
| VM high CPU | CPU Utilisation | Above 90% for 1 interval | Catches VMs under sustained heavy load before performance degrades |
| Storage low availability | Availability | Below 100% for 1 interval | Immediately flags any degradation in storage service availability |
| High ingress traffic | Ingress | Above expected baseline | Identifies unusual data write spikes that could indicate unexpected usage or misconfigured applications |
| High server latency | Success Server Latency | The above-defined ms threshold for 2 intervals | Detects storage performance degradation before it impacts dependent applications |
| Storage capacity is nearly full | Used Capacity | Above-defined Bytes threshold | Prevents storage limits from being exceeded unexpectedly |
| Cost threshold exceeded | Actual Total Cost | Above budget amount for the MONTHLY period | Alerts when Azure spending exceeds a defined monthly budget before the billing cycle closes |
Once saved, all triggers for a resource are listed in the Triggers table under the Alarm Rule section. Each row shows the trigger title, alarm severity, whether notifications are configured, and whether a script is set to run. You can edit or delete any trigger at any time using the action icons on the right.
