IoT Platform allows you to check the network status of each device. A device that accesses a network by using Wi-Fi can send the network status data to IoT Platform by using a specified topic. This topic describes how to view the network status of a device in the IoT Platform console.

Background information

For more information about device topics, data formats of Alink, and errors that are reported, see Device network status.

If your device uses AliOS Things V3.0 or later, the device automatically checks and sends network status data. For more information about network errors, see the err_stats table in Device network status.

Procedure

  1. Log on to the IoT Platform console.
  2. On the Overview page, find the instance and click the instance name to go to the Instance Details page.
    Notice Enterprise Edition instances are available only in the China (shanghai) and Japan (Tokyo) region. If your IoT Platform is not activated in the China (shanghai) or Japan (Tokyo) region, skip this step.
    Overview
  3. In the left-side navigation pane, choose Maintenance > Real-time Monitoring.
  4. On the Real-time Monitoring page, click Device Network Status.
  5. Select a device and a time range.
    The network status data of the selected device and time range is displayed.
    Table 1. Descriptions of the network status of the device
    Field Description
    Reported At The time when IoT Platform received the network status data.
    Collected At The time when the device collected the network status data.
    Note The device immediately sends the network status data to IoT Platform after a network error occurs or when the device collects data at a scheduled point in time. In other scenarios, the device may not immediately send the network status data after the device collects the data.

    If the data that the device sends to IoT Platform does not include a timestamp, no time is displayed.

    RSSI (dBm) The strength of the signal that is received.
    SNR (dB) The signal-to-noise ratio of the wireless signal.
    Wireless Signal Packet Loss Ratio (‰) The packet loss rate.
    Network Connection Method The method that is used to establish a network connection to the device. Only devices that can be connected by using Wi-Fi are supported.
    Error Description Click View Details to view the details of errors and the number of times that each error occurs.
    Note The View Details button appears only when network errors are reported by the device.
