New features

This release provides the following graphing enhancements:
  • Occasionally, Service Impact receives information about an unknown component or device that is needed for an event. When this occurs, a targeted graph update models just the unknown entity's subgraphs. To allow the modeling workflow to complete, a "placeholder" is immediately created for the unknown entity. Impact graphs are quickly refreshed without delay to event processing.

    The targeted graph update allows mission-critical event and service event monitoring and alerting to resume with minimal downtime. During the restore and rebuild of the Neo4j graph database, service event processing resumes quickly, regardless of the size and number of service models.

  • New commands for zenimpactgraph run update enable you to manually rebuild a subset, rather than performing a rebuild of all service models. A manual rebuild is rarely required, but can be performed if necessary to repair a subset of nodes.

For information about these enhancements, refer to the Zenoss Service Impact User Guide.
