Configure threshold-based alerts across all VMware entity types to detect performance and availability issues proactively. Alarms can be set at the individual entity level or applied to groups of VMware resources.
Cloudmon supports alarms for all monitored VMware entities including vCenters, ESXi hosts, clusters, virtual machines, datastores, and resource pools. When a configured threshold is breached, Cloudmon raises an alarm and can notify the relevant team members via email, SMS, or third party integrations. Alarms can be configured at the individual entity level from the entity's Settings page, or at the group level via Alarm Rules to apply consistent alerting across all entities of the same type.
| Field | Description |
| Metric | The specific metric to monitor, such as CPU usage, memory utilisation, network bandwidth, or disk space. |
| Threshold | The value the metric must breach to trigger the alarm, for example CPU usage exceeding 80% or available disk space dropping below a defined level. |
| Severity | The alarm severity level. Options are Critical, Trouble, and Attention, helping to prioritise alerts based on the impact of the issue. |
| Notify To | The users or user groups who will be notified when the alarm fires, ensuring the right team members are informed promptly. |
To apply an alarm rule across all entities of a specific VMware type simultaneously, navigate to Settings → Configurations → Alarm Rules, click Add, and select the relevant VMware entity type such as VMware ESXi, VMware VM, or VMware Datastore. Add triggers for the required metrics and associate the rule with the relevant device groups. 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.
