9 Getting Started with Service Impact Analysis

Service Impact Analysis provides the network user with the ability to visualize the services, resources, locations, networks, and other items impacted due to an event generated on a physical, logical, or virtual resource. The system correlates the event generated by the network due to a fault at a node or subnode level of shelf, card, port, or device interface. Service Impact Analysis visualizes the analyzed data in the form of charts and reports. The data is collected from an assurance system, for example: Oracle Communications Unified Assurance, which in turn collects the live data from the networks. You can view, sort, and analyze the impacts, events, and generate reports. You can customize your search and reports using filters.

The supported resource types are:

  • Physical Port
  • Device Interface
  • Equipment
  • Physical Device
  • Logical Device

The supported resource sub types are:

  • Shelf
  • Card

Accessing Service Impact Analysis

About Event Statuses

The events have the following statuses that you get from the assurance system:

Table 9-1 Event Status

Event Status Description
RAISED The alarm is detected.
UPDATED The alarm status is successfully updated.
CLEARED The alarm is resolved and is no longer active.
REJECTED The alarm status change is rejected due to an error or other reasons.

About Analysis Status

Service Impact Analysis has the following lifecycle statuses:

Table 9-2 Analysis Status

Analysis Status Description
PENDING The event is received but not assigned to anyone to analyze.
ASSIGNED A user (or Owner) is assigned to analyze the impact.
INITIATED The system has started analyzing the impacts in UIM.
COLLECTED The system has completed the analysis of impacts in UIM. Analysis status value is changed to COLLECTED if the analysis is completed successfully.
FAILED The system has failed in analyzing the impacts in UIM. If the initiate analysis is not completed successfully, the analysis status is changed to FAILED.
ANALYZING The user (or Owner) has started analyzing the impact.
COMPLETED The analysis of the impact is completed by the user (or Owner) and the system.

Note:

The Analysis Status can be COMPLETED only if all the impacted items are QUALIFIED or DISQUALIFIED.
