Network dashboard

From the Network dashboard, you can monitor how effectively data is transmitted over the data link, network, and transport (L2 - L4) layers.

Each chart in the Network dashboard contains visualizations of network metric data, organized by region. You cannot edit or delete the Network dashboard. However, you can create your own custom dashboard to monitor specific metrics that are relevant to you.

The following information summarizes each region.

Network L2 Metrics
Monitor the throughput rates over the data link (L2) layer by bits and packets, and monitor the types of frames transmitted. You can also determine how much data is sent to receivers by unicast, broadcast, or multicast distribution.
Network L4 Metrics
Monitor data transfer latency over the transport layer (L4). View TCP activity through connection, request, and response metrics. This data can indicate how effectively data is sent and received across the transport layer in your network.
Network Performance
Monitor how network performance is affecting applications. View overall network throughput by reviewing the throughput per application protocol and the magnitude of high TCP round trip times.
Network L3 Metrics
View data throughput at the network layer (L3) and see packets and traffic by TCP/IP protocols.
View a breakdown of packets and traffic by Differentiated Services code points, which is part of the DiffServ network architecture. Every IP packet contains a field to express the priority of how the packet should be handled, which is called differentiated services. The values for the priorities are called code points.
Multicast Groups
View traffic that is sent to multiple receivers in a single transmission, and see packets and traffic by each receiver group. Multicast traffic on a network is organized into groups based on destination addresses.
Note:In the ExtraHop Command appliance, you can display the Network dashboard for each Discover appliance. The appliance name appears in the navigation bar; click the down arrow next to the appliance name to pivot the display to other connected Discover appliances.
