Visualize Flows Traffic by Quality of Service (QoS)
Network traffic prioritization is easier when you can visualize flows by QoS. You can quickly verify that your configuration for priority traffic works as specified, and make changes as needed to ensure optimal service performance.
Able to handle up to 300,000 data points per second with flows, and configurable to handle more, OpenNMS processes, aggregates, and exposes this data for improved streaming analytics. OpenNMS’ Helm plugin for Grafana allows you to create flexible dashboards to view this data as time series or tabular views.
Helm now includes options to filter flows traffic by ToS/DSCP (Differentiated Services Code Point). Using the Deep-Dive Flows Dashboard, simply select the DSCP value (or combination of values) from a drop-down list for the QoS you want to visualize (class selector, IP precedence, assured forwarding, expedited forwarding). The ECN (explicit congestion notification) drop-down allows you to further filter on this value to see which flows use ECN-capable transports, and congestion reports for them.
