If you're responsible for managing your organization's network, you'll want to use three Control Center features that allow you to check the status of your network: network maps, Quick Report: At-a-Glance, and Quick Report: Top Hitters.
To check for network outages on the map:
Green circles on the map mark service locations with no open tickets and red triangles mark service locations with open tickets. For circuit information and ticket status, hover over a location. For detailed information, click a location.
Beneath each gauge are two abbreviations: LWM and HWM. LWM means low water mark and indicates the lowest network use during the sample timeframe, which is a 15-minute period during the last hour. HWM means high water mark and indicates the highest network use during that same period. If your network exceeds 80% use during the sample timeframe, these numbers will be in red, indicating the circuit may require further attention.
