| == Dashboard ==
| |
| | |
| | |
| 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.
| |
| | |
| ==== 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 :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.
| |
| | |
| ==== 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.
