Monitor Network Performance

Dashboard network statistics

The network statistics view is a real-time monitoring interface that displays the performance and operating parameters of devices across different network sections.

  • Shows the number of devices currently connected to IW Monitor, compared to the total associated devices.

  • Displays device latency (Average latency) values across the network or section for the last six hours.

  • It provides aggregate throughput for TX and RX, the number of sent and received packets per second, the current number of edge devices, and average uptime values for each network section.

Network Statistics Reference Information

The network statistics view provides detailed information about the performance and health of each network section and its devices.

  • Number of devices currently connected to IW Monitor, in relation to the total number of devices associated with IW Monitor.

  • Device latency (Average latency) values across the network or section during the last six hours.

  • Aggregate network throughput transmitted (Throughput TX) by all devices in the network during the last six hours.

  • Aggregate network throughput received (Throughput RX) by all devices in the network during the last six hours.

  • Aggregate number of data packets sent (Sent Packets/s) by all devices in the network during the last six hours.

  • Aggregate number of data packets received (Received Packets/s) by all devices in the network during the last six hours.

  • Current number of edge devices (Edge devices).

  • Average network or section uptime value (Average uptime). The average uptime value is the combined percentage of time for each network device or section connected to the IW Monitor in the last seven days.

Figure 1. Network Statistics Overview

When a performance-related fault occurs, a thin red box appears around the affected section to indicate the need for immediate investigation.

The + ADD SECTION button at the bottom allows you to customize the section with the device information you want to monitor. To add a new section to an existing network, see Create a new section.

Use the Table View to monitor devices

The Table View is a feature in IW Monitor that displays all devices in a tabular format, showing their status, attributes, and section assignments.

  • Devices without an assigned section appear under Uncategorized .

  • Devices assigned to specific network sections appear in their respective sections.

  • Each device entry displays parameters including Status, Mode, Label, IP Address, Mesh ID, Firmware Version, Role, Frequency, TX Power, Max TX Power, and Channel width.

Device Table View Reference Information

The Table View provides a comprehensive overview of all devices with their current status and key operational parameters. Users can search for devices, filter by status, and review detailed attribute descriptions.

  • Users can search for devices by Mesh ID, assigned device name, or IP address.

  • Users can filter devices by status: Critical , Warning , or Disconnected .

  • Device attributes and their descriptions are provided in the table.

View device statistics in real time

IW Monitor provides network statistics that allow you to view the network-related performance of any device in the current network. You can view device statistics as events occur in real time. You can also view a performance graph showing the device's historical performance over time.

Procedure

Step 1

Click Data Analysis.

Step 2

In the TIME field, you can switch between real-time and historical data for analysis.

  1. To view statistics for a device during a specific period, select the History tab.

  2. In the Custom time range field, select the start and end dates and times for the range.

    Note

     

    The selected duration can't be more than 1 hour.

Step 3

In the SEARCH DEVICE field, search for a device by mesh ID, assigned device name, or IP address.

Step 4

In the ANALYSE field, click Confirm to proceed.

A real-time statistical view of the device appears. If you select the History tab, a time slider for the chosen period is also displayed.

  1. The first graph shows the received signal strengths for the device and other radio units that it could connect to.

    • The upper left corner of the graph shows whether the device currently accepts handoff requests.

    • If the chosen device is currently connected to a Fluidity-enabled (vehicle-mounted) radio unit, a thick, dashed black line is superimposed over the Fluidity device's RSSI line. This line is the RSSI envelope and represents the strongest available signal.

      Note

       

      In the right-hand section of the graph, devices to which the current device is connected are listed in descending order of received signal strength (RSSI).

  2. The throughput graphs display throughput statistics over time in Mbps, shown for the selected device and its current connection.

    Note

     

    The left graph shows uplink statistics (data flow from the current unit), while the right graph shows downlink statistics (data flow to the current unit).

  3. The LER/PER graphs show the current link error rates, packet error rates (expressed as percentages over time), and comparative signal modulation rates. LER and PER are shown for both the selected device and its current connection.

    Note

     

    The left graph shows uplink statistics (data flow from the current device), while the right graph shows downlink statistics (data flow to the current device).

  4. The graphs in the fourth row show the modulation and coding schemas (MCS) for the selected device and its current connection.

    Note

     

    The left graph shows uplink MCS statistics for the current device, while the right graph shows downlink MCS statistics for the unit to which the current device is connected.

  5. The upper left corner of the graph shows whether the device currently accepts handoff requests.

    Note

     

    This graph is shown only for vehicles.

Step 5

Click Edit to view statistics for a different device.
