Pending Instances

When an alert is raised, a special Alert event is generated and persistently stored in the Iotellect Server database. Alert events that are not acknowledged are called pending alert instances. See the events topic for more information about events and event acknowledgement.

It's important to distinguish between Active and Pending alert instances.

The pending instances of every alert may be controlled using the Manage Pending Instances action, defined in the Alert context. This action shows when and why the alert was raised and lets you delete or acknowledge pending alerts. Alert instances that have already been acknowledged are not shown in the list.

When one or more unacknowledged alert events exist, the alert remains in the Active state. This state is indicated in Iotellect Server user interfaces by a special icon. The active state indicates that some attention is required to solve the problem indicated by the alert. When the problem is solved, a system operator may launch the View Pending Alerts action and acknowledge all pending alert instances. Alert will be put back in the "Enabled" (normal) state, indicated by the icon.

Non-acknowledged instances may force an alert to switch into the Active state only if the Allow pending alerts setting is enabled.

To see pending instances of a certain alert, launch the View Status action and check the Active Instances table. Pending instances have a Pending mark in the Type column.

To see all pending alerts in the system, run the Active Alerts query.

When configuring an alert, one of the properties is called Allow Pending Alerts. If you disable this (i.e., disallow pending alerts for this particular alert you're configuring), the alert won't be shown in the Pending Alerts list even if it wasn't acknowledged. It also won't be escalated.
