Exploring the Network Visibility dashboard

Use Network Visibility to monitor and measure performance for your Lumen services. It collects network-performance metrics, summarizes them to isolate performance issues, and reports the results. Select various network components, time ranges, and sample sizes to view key performance indicators (KPIs) that measure the health of your services. You can also set performance thresholds to be notified if your services exceed the threshold.

Network Visibility collects and summarizes your circuit-specific data such as circuit utilization and bits per second (passive metrics) to provide trend analysis of usage patterns to plan for circuit upgrades, configuration changes, and scaling.

Network Visibility (showing Utilization KPI)

Click Service Mgmt, then Network Visibility.

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.

Dashboard KPIs (key performance indicators)

Network Visibility offers KPIs to help you monitor permformance, utilization, and issues related to your services. To view more information, click the KPI.

To view locations with high or elevated utilization, click the Utilization KPI:

Elevated Utilization: average utilization above 65% during the latest 5-minute sample.
High Utilization: average utilization percentage above 85% during the latest 5-minute sample.

Utilization data is calculated as follows:

bits = bytes * 8
bits per second = Bits / time delta (usually 300 for a 5-minute interval)
utilization average = bits per second / committed bandwidth

To view locations with impacted or critical performance, click the Performance KPI:

Critical performing: packet-data delivery less than 95% during the latest 5-minute sample.
Impacted performing: packet-data delivery less than 99% during the latest 5-minute sample.

Network Visibility (showing Performance KPI)

To view maps locations that are identified as Down, click the Down Services KPI:

Down service: Interface Oper status is down during the latest 5-minute sample.
Up service: Interface Oper status is up during the latest 5-minute sample.

Network Visibility (showing Services KPI)

To view locations with threshold alerts (watches and warning), click the Thresholds KPI:

Warnings alerts
- Aggregate utilization
- Active metrics (if you have services with active metrics)
  - latency by class of service
  - jitter by class of service
  - packet data delivery by class of service
Watches alerts
- Aggregate utilization
- Active metrics (if you have services with active metrics)
  - latency by class of service
  - jitter by class of service
  - packet data delivery by class of service
