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.
Notice
Rate events are included from VAST Cluster 2.1.0.
