Different types of events can be defined to trigger alarms in different ways. The main types of events are:
Object Modified. With this type of event, an alarm is triggered on and off when an object property reaches specified values.
An alarm is triggered on when the cluster state is failing or failed, and then triggered off when the cluster state is active again.
An alarm is triggered on when the attached property of an SSD turns false, and triggered off when it changes to true.
Threshold. These events trigger alarms when a property value crosses a specified threshold.
An alarm is triggered when NVRAM has 100 or more disk media errors.
An alarm is triggered when cluster capacity is greater than or equal to 90 %.
Rate. These events trigger alarms if a property value exceeds a threshold within a given time frame.
An alarm is triggered when CNode memory is raised by more than 10% in 24 hours.
An alarm is triggered when a CNode has over 100 PCI errors in a 12 hour period.
