Event Types

The main types of events are:

Object Modified. This type of event is triggered on and off when a property reaches specified values.

Examples:
- An event is triggered on when the cluster state is failing or failed, and then triggered off when the cluster state is active again.
- An event is triggered with the attached property of an SSD is false, and triggered off when it changes to true.
Threshold. These events are triggered when a property value crosses a specified threshold.

Examples (default):
- An event is triggered when NVRAM has 100 or more disk media errors.
- An event is triggered when cluster capacity is greater than or equal to 90 %.
Rate. These events are triggered if a property value exceeds a threshold within a given time frame.

Examples (default):
- An event is triggered event when CNode memory is raised by more than 10% in 24 hours.
- An event is triggered when a CNode has over 50 PCI errors in a 12 hour period.

Rate events are included from VAST Cluster 2.1.0.
