- An example of this would be an average rule for all CPUs over 10%
```sql
SELECT *,AVG(processors.processor_usage) as cpu_avg FROM devices,processors WHERE (devices.device_id = ? AND devices.device_id = processors.device_id) AND (devices.status = 1 && (devices.disabled = 0 && devices.ignore = 0)) = 1 HAVING AVG(processors.processor_usage) > 10

## Procedure
You can associate a rule to a procedure by giving the URL of the procedure when creating the rule. Only links like "http://" are supported, otherwise an error will be returned. Once configured, procedure can be opened from the Alert widget through the "Open" button, which can be shown/hidden from the widget configuration box.
