Viewing Failure Simulation Reports

 

After you run failure simulations for scheduled maintenance events to test the resilience of your network, you can view the failure simulation reports for those maintenance events. The reports are stored on the NorthStar Controller server until the user deletes the Maintenance event from the user interface. When a maintenance event is deleted, any associated reports are also deleted.

The following reports are available for each maintenance event simulation:

Link Peak UtilizationFor each link, this report shows the peak utilization encountered from one or more elements that failed.
Path Delay InformationShows the worst path delay and distance experience by each tunnel and the associated failure event that caused the worst-case scenario.
Peak Simulation SummaryShows the summary view of the count, bandwidth, and hops of the impacted and failed tunnels.
Tunnel Failure InformationShows the tunnels that failed to reroute.
LSP Path ChangesShows changes to the tunnel paths, number of hops, path cost, and delay.
RSVP Link Utilization ChangesShows changes to the tunnel paths, number of hops, path cost, and delay.

To access and view maintenance event simulation reports:

  1. Navigate to Applications > Reports. In the left pane of the Reports window, reports are grouped under the maintenance events for which simulations were run.
  2. Select the report you wish to view. It is displayed in the right pane.
