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.
The gauges in the At-a-Glance report show use statistics for your network. From the list, you can select either layer 3 or layer 2 services.
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.
The Top Hitters report ranks your circuits based on current use. The data is based on a 15-minute sample taken within the last hour.
Circuits with 80% use or greater are highlighted in red. If that condition is frequent, you may need more bandwidth.
