...
Go to Infrastructure → Alarms
Select a physical machine, rack, or datacenter with custom metrics, or a VM from the hierarchy
Click the + add button
Enter the alarm details
The Name must be unique and it can be up to 128 characters
The platform will use the Description with the alarm name and if appropriate the VM name to identify the alarm, for example, when creating an alert
For the Metric select one of the available metrics. The platform fetches all metrics, even if you do not display them.
Optionally, select one or more Dimensions if the metric has multiple dimensions. For example, if a VM has multiple hard disks, then the
disk read bytesmetric may have a dimension for each disk.For Last datapoints in period, the default value is All data points and the minimum value of the time period is 1 minute. However, it is not useful to evaluate metrics more often than the server is obtaining them. We recommend a value of 60 minutes.
Click Save
The platform will create the alarm for the metric. If you would like the platform to notify you when this alarm activates, create an alert for it in the Control view. You can create multiple alerts that include multiple alarms.
