Dashboard screen shots

BPS graph

By clicking on the graph, details for that time sample is shown (“Sample details” panel). 

The time can be changed by using the “Second” pull-down menu (Options 10 seconds, 1 minute and 1 hour). 

The graph can show the BPS data for each individual monitored network port or for all ports combined. 

The displayed data can be exported as a “cvs” file and can also be shown in table format.

Packet size graph

The “Packet size” graph shows the distribution of captured packets into different size buckets.

The time interval for which the statistical data is shown can either be one minute, one hour or one day.

Data for all individual network ports can be shown.

System and Disk data

The System Data panel shows general data about the NTA system.

The Disk Data panel shows the status of the NTA disk system.

Port, Capture, Filter and Slicing data

Port data:
The status of the NTA ports

Capture data:
Overview of what has been captured and stored to disk on the individual network ports.

Filter data:
Overview of how much has been captured and how much has been discarded by different filter types.

Slicing data:
Overview of how much has been captured and how much has been discarded by different slicing types.

Packet size table

The Packet size table shows the distribution of captured packets into size buckets.

Analysis screen shots

Analysis filter example

An analysis filter example with three defined filters. 

First filter includes packets received on network port 0 received on the 27 September 2018 in the time between 13:30 and 13:35

Second filter includes IPv4 packets with an IP source address of 1.2.3.4 and a destination address of 5.6.7.8 and has the following packet headers Ethernet->MPLS->MPLS->IPv4->TCP->HTTPS

Third filter include packets with IPv6 protocol somewhere in the protocol stack and with atleast two VLANs where the second VLAN label is 123

The NTA supports many more filter types than is shown in this example.

Maximum graph

This is an example of an analysis maximum graph.

The graph shows the 100 flows with the most packets for selected packets. The 100 flows with the most bytes, highest bandwidth or longest duration can also be shown.

The data can also be shown as a table and can also be exported as a “csv” file (shown on a following screenshot).

Clicking on one of the bars will display details for the flow (shown on a following screenshot).

Maximum graph (flow details)

Example of an analysis maximum graph where a graph bar has been clicked to show details.

The flow and the UDP protocol have been expanded.

The other protocols can also be expanded and the packets making up the flow can be shown.

CSV data from Maximum graph

Example of  CSV data exported from an analysis maximum graph (displayed in spreadsheet).

Protocol Graph

The Protocol graph shows protocol distribution for the selected flows.

Using the pull down menu it can be selected whether the graphs should be shown for the flows most packets or most bytes.

Maximum table

Example of part of an analysis maximum table.

Flow 3 has been expanded and for flow 3 the Ethernet part of the protocol has also been expanded.

 

Protocol table

Example of part of an analysis Protocol table.

Protocol Analysis panel

Example of an analysis packet panel.

The packet analysis functionality is used to inspect the selected packets. Packets are shown in time order and navigation between the selected packets is done using the buttons at the bottom.

Flow Analysis panel

Example of a flow analysis panel.

The flow analysis functionality is used to inspect the selected flows. Flows are shown in time order and navigation between the selected flows is done using the buttons at the bottom.

Replay screen shots

Replay control example 1

Example showing a replay session setup.

The session is setup to replay (transmit) traffic on network port 2.

Packets from one file is going to be replayed.

1,000,000 packets are transmit and with the same speed (Inter-Frame Gab IFG) as when captured.

Replay control example 2

Example showing a replay session setup.

The sessin is setup to replay (transmit) traffic on network port 2 and 3. 

On port 2 packets from one file is transmitted while on port 3 packets from two other files is transmitted.

Port 2 is setup to be the “Master” for port 3, this means that the speed and duration setting for port 2 also will be used for port 3, and that when the transmission is started (and stopped) for port 2 this will also be done for port 3.

Test data is set up to be transmitted in 3600 seconds (one hour) with a fixed speed of 5 Gbps.

Duration can be specified as: “Infinite”, “N loops”, “N packets”, “N bytes” or “N seconds”.

The speed can be specified as: “As captured”, “Percent speed increase”, “Fixed BPS” or “Random BPS”.

Replay file browser

Example of the replay file browser.

The replay file browser is used to specify which files should be replayed. 

The read button will add the file to the list of files to be replayed. 

The delete button will permanently delete the file from the NTA. 

The download button will download the file from the NTA to the user browser PC. 

The “upload replay file” button will upload a replay file to the NTA.

Replay session browser

Example of the replay session browser.

The replay session browser is used to manage replay sessions. 

Replay setups (such as networks ports used and test duration) are saved as replay sessions. 

Replay sessions can be saved, read and deleted.

Replay statistics

Example of NTA replaying packets.

Packets are transmitted on network port 2 and 3.

While packets are transmitted statistics is shown for “Duration“, “Packets“, “Bytes” and “BPS“.

Management screen shots

Capture management

Example of capture management panel.

In this panel it is defined which ports capturing is enabled and for each enabled port which kind of slicing should be performed (if any).

The following slicing can be performed:

  • Discard of the payload part of the captured packets only storing packet headers and timing information.
  • Discard encrypted part of the captured packets (if any).
  • Discard all the parts of the packet after a specified packets offset.

User management

Example of user management panel.

In this panel it is defined which persons can use the NTA.

For each person it is also defined which functionality should be available for the users.

Help screen shots

Miscellaneous screen shots

NTA top lines

This screen shot shows the NTA top lines. This lines are shown on all NTA pages. 

The first line is a status line. The icon on the left is used to change the size of the side bar. Next is the NTA model name and the NTA date and time. In the top right is shown a wrench. Clicking on the wrench will enable configuration of what data should be displayed on the key figures line below (the key figures line can also be disabled). 

The second line shows key figures. The key figures shown are defined by the user. 

The third line is a navigation line. This line is showing a list of page elements on the page. By pressing on a page element the view will move to that page element.
