Alerts are a way of notifying changes and threshold limits in a hybrid cloud environment. This is done through either an e-mail or an SNMP trap. Before we can work with creating and using alerts, a couple of prerequisites need to be performed:
Enable the Notifier server role by the following steps:
Navigate to Configure and then to Configuration.
On the server settings page, under the Server Control section, select the Notifier role and then click on Save.
Configure the SNMP and SMTP
Alerts can be created for virtual machines, instances, and CloudForms Management Engine operations.
They can be created for each of these categories based on some default values provided by CloudForms Management Engine, or using custom expressions.
