The dashboard gives a quick overview about the network traffic processed by the Network Multimeter.

There are three different dashboards available which focus on different aspects of the network traffic.

  1. Top Users
  2. Quality
  3. Triple play

Top Users dashboard

The Top Users dashboard provides an overview of the most active entities and protocols in the network traffic.

All sections can be minimized or maximized by click on the arrow next to a section.

Active Interface Overview

This overview lists all active network interfaces used for traffic analysis.

A history graph shows the receive bitrate for each active interface.

The table next to the history graph contains the link status for each active interface including the active link speed, the current receive bitrate, the link utilization and a button that allows to capture the traffic of that particular interface. If a NIC filter has been configured, the filtered amount of traffic is shown in the last row of the table.

If no interface is active or the system is operating in one of the replay modes (e.g. PCAP replay, packet ring buffer replay) instead of the Active interface overview history graph a Traffic overview history graph is shown which displays the combined traffic processed by the system.

Active Groups Overview

The group list provides an overview of all groups for which traffic has been seen. The traffic counters and received traffic over time as a graph are shown for each group. A PCAP button is available for capturing the traffic for that group. This section is only visible if there are groups configured.

Top sending IPs / Top receiving IPs

The Top sending IPs and Top receiving IPs panels show the top 5 most active sending/receiving IP addresses.

A button is available to toggle between list view and graph view.

In live view mode, the IPs are listed with the most bytes during the last minute.

If an interval is selected, the IPs with the most bytes in that interval are listed.

The list contains the IP address and name (if known) as well as the current packet rate and bit rate.

There is also a button to directly capture traffic for the corresponding IP address.

Each IP address in the list can be clicked to get to the IP details statistics of that IP, or the Top sending IPs / Top receiving IPs link can be clicked to get to the main IP module.

Top MACs

Similar to the Top sending IPs / Top receiving IPs , the Top MACs panel shows the top 5 most active MAC addresses.

A button is available to toggle between list view and graph view.

In live view mode, the MAC addresses are listed with the most packets during the last minute. If an interval is selected, the MAC addresses with the most packets in that interval are listed.

The list contains the MAC address and name (if known) as well as the current packet rate and bit rate. There is also a button to directly capture traffic for the corresponding MAC address.

Each MAC address in the list can be clicked to get to the MAC details statistics of that MAC, or the Top MACs link can be clicked to get to the main MAC module.


Top protocols

The Top Protocols panel shows the top 5 most active network protocols.

A button is available to toggle between list view and graph view.

In live view mode, the protocols are listed with the most packets during the last minute. If an interval is selected, the protocols with the most packets in that interval are listed.

Each protocol in the list can be clicked to get to the detailed statistics for that protocol, or the Top protocols linked can be clicked to get the main L7 module.

Quality dashboard

The Quality dashboard provides an overview of various quality-related metrics and their development over time.

Burst analysis

This graph shows the combined network interface throughput utilization which is measured with 1ms resolution. A link to the detailed Burst analysis page is provided Burst analysis.


Response time

Here the average TCP data response time and the combined average application response time are shown. There are two links which navigate to the detailed TCP response time analysis page and to the application response time overview page.


Jitter

This graph shows the average RTP jitter and the average Profinet jitter.

Links above the graph navigate to the respective detail pages.


Packet loss

This graph shows the packet loss percentage for RTP, IPSec and Profinet.

Links above the graph navigate to the respective detail pages.


TCP retransmitted data / TCP retransmission ratio

The TCP retransmitted data and TCP retransmission ratio graphs show the amount and ratio of TCP data that was retransmitted due to packet loss.

More detailed information can be found when following the link to the TCP module.


TCP zero window packets

The TCP zero window packets graph shows the global number of TCP zero window packets over time. More detailed information like the number of TCP zero window packets per IP can be found when following the link to the TCP module.


Triple play dashboard

The triple play dashboards shows global data about VoIP and RTP protocols.

VoIP statistics

The VoIP statistics panel shows SIP calls and their associated metadata.


RTP statistics

The RTP statistics panel shows RTP traffic of the last minute or of the selected interval.

A pie chart shows the distribution of currently used RTP codecs.

The Top RTP codecs table shows detailed statistics for the five most used RTP codecs. A PCAP button allows to capture traffic for a certain codec.
