Table 21-6. Datastore Condition and State Triggers
Trigger Type Trigger Name Description
Condition Datastore Disk
Overallocation (%)

Client. If you disable this alarm, the datastore status will be displayed as
Unknown.
State Datastore State to All
Hosts
n
Connected to all hosts – The datastore is connected to at least one
host.
n
Disconnected from all hosts – The datastore is disconnected from at
least one host.
Event Triggers
Event triggers monitor events that occur in response to actions related to managed objects, the vCenter Server
system, and the License Server.
Event triggers use arguments, operators, and values to monitor operations that occur in the vServer System.
Because the occurrance of the event gives you information about the operation occurring in your environment,
you usually will not need to configure arguments for them. However, some events are general and
configuration might be required to set the alarm on the desired information. For example, the Hardware Health
Changed event occurs for a variety of different subsystems on a host.The preconfigured datacenter alarm Host
Hardware Fan Health uses the Hardware Health Changed event with the following two arguments to set a
warning condition when a fan is not operating:

Argument Operator Value
group equal to Fan
newState equal to Yellow
NOTE Due to the large number of events tracked by vCenter Server, the event table for each object does not
contain definitive lists of events. Instead, it provides a subset of the events available for alarm triggers.
Event Trigger Components
Event triggers are composed of a trigger type, a trigger status, and triggering conditions.
Table 21-8 describes the components of event alarm triggers.
