== Dashboard ==
#[[Dashboard ]]
The dashboard gives a quick overview about the network traffic
#[[Custom dashboards]]
processed by the Network Multimeter.
#[[Global traffic ]]
 
#[[Multi IP view]]
There are three different dashboards available which focus on different
#[[Multi SIP view]]
aspects of the network traffic.
#[[Interface statistics]]
 
#[[Storage]]
===== Top Users dashboard =====
#[[PCAP parallel analysis]]
 
#[[Interactive graph features]]
The Top Users dashboard provides an overview of the most active entities
#[[Back-in-Time functionality]]
and protocols in the network traffic. All sections can be minimized or maximized
#[[Virtual Link Group functionality]]
by click on the arrow next to a section.
#[[Live filtering of tables]]
 
#[[Reports ]]
===== Active Interface Overview =====
#[[Process traffic capture from remote device ]]
 
#[[User defined names ]]
This overview lists all active network interfaces used for traffic analysis.
#[[NetFlow/IPFIX interface ]]
A history graph shows the receive bitrate for each active interface.
#[[Scoring of response times ]]
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 :doc: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.
 
==== 1.2 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.
(see: [[Usage/ Top MACs|burst analysis module]]).
 
 
===== 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 :doc:`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 :doc:`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.
