If you want to change the conditions or delivery for a threshold alert, you can edit the alert in Network Visibility. For example, you can change the utilization threshold from 50% to 75% or change the email address(es) Control Center sends a threshold alert to. If you no longer need an alert, you can delete it to stop Control Center from notifying you.
Control Center opens the Network Visibility dashboard. On the map, Control Center shows locations with services needing your attention. Key performance indicators (KPIs) show services with high utilization or critical issues, services that are down or have threshold warnings, as well as open tickets and scheduled maintenance for your services. Use the Map View and List View links above the KPIs to toggle between views.
Click the Threshold Alerts KPI.
Control Center shows locations with threshold watches or warnings (if any).
Select the service you want to manage threshold alerts for by doing one of the following:
