    Stats Reported for AirLink OS routers

    This section lists some of the commonly used stats that are calculated by the AMM based on the latest reported events or data points from the gateway.

    • AOS Heartbeat: time since the last AirLink OS heartbeat event from the LwM2M path.
    • ApplicationVersion: version number of the application aos-delsadapter.
    • BootReason: the reason why the router was booted up. In normal operation, this would always be “Ignition”.
    • CallUp: indicates if there is an active link up.
    • CPU-Temperature: CPU temperature.
    • Ignition: if the ignition is on or not. Router must be connected to the vehicle using OBD and VEHICLE IGNITION WIRING set to Connected to Airlink gateway Ignition Sense Input Line.
    • MainBattery: voltage being reported at the power input terminal of the router.
    • Platform: the type of platform (e.g. XR60, XR80, XR90).
    • ReportIdleTime: time since last batch of stats received via the DELS path for that router (default “gateway heartbeat” / reporting gap)
    • ShutdownReason: reason for AirLink OS router shutdown.
    • SoftwareVersion: the version of the gateway’s software.
    • Temperature: the internal ambient temperature in the gateway.
    • UpTime: the amount of time that the gateway has been booted up.

    Communication Stats

    The format of a communication stat is <interface>#-<stat_name>.

    Interface identifies the connection type.

    • c - cellular
    • e - ethernet
    • w - Wi-Fi

    The # sign represents the port number. Since an AirLink OS router can have multiple ports, the number indicates which specific port the stat belongs to. LinkLocation is defined as the combination of <interface>#.

    The following are some of the more commom communication stats.

    • [LinkLocation]-Active: indicates whether the current default route is accessbile.
    • [LinkLocation]-CallUpTime: length of time that the current data call has been in place.
    • [LinkLocation]-IPAddress: the ip address of the link.
    • [LinkLocation]-RSRP: the average power received from a single reference signal. Typical range is around -44dbm(good) to -140dbm(bad). Applies to 3G and 4G LTE only.
    • [LinkLocation]-RSRQ: indicates quality of the received signal. Typical range is around -19.5db(bad) to -3db(good). Applies to 3G and 4G LTE only.
    • [LinkLocation]-SINR: signal to noise ratio of the given signal. Applies to 3G and 4G LTE only.
    • [LinkLocation]-RSSI: represents the entire received power present in the received signal. Applies to 3G and 4G LTE only.
    • [LinkLocation]-5G Band Number: a standardized numerical identifier assigned by 3GPP that designates a specific range of radio frequencies and duplex mode used for 5G wireless communication. Applies to 5G only.
    • [LinkLocation]-5G Band Width: refers to the width of the radio frequency channel (measured in MHz) allocated to a 5G signal, where a wider bandwidth allows for higher data throughput.
    • [LinkLocation]-5G RSRP: the average power received from a single reference signal. Typical range is around -44dbm(good) to -140dbm(bad). Applies to 5G only.
    • [LinkLocation]-5G RSRQ: indicates quality of the received signal. Typical range is around -19.5db(bad) to -3db(good). Applies to 5G only.
    • [LinkLocation]-5G SINR: signal to noise ratio of the given signal. Applies to 5G only.
    • [LinkLocation]-MobileDirectoryNumber: cellular phone number.
    • [LinkLocation]-ICCID: integrated circuit card identifier. The SIM card itself.
    • [LinkLocation]-State: state of the interface port.
    • [LinkLocation]-Up: if the link is connected or not.

    Example:

    • c1-Active: cellular interface, port 1, Active stat.
    • e2-CallUpTime: ethernet interface, port 2, CallUpTime stat.
    • w1-Up: Wi-Fi interface, port 1, Up stat.

    Note: LinkX indicates the current active WAN interface and provides the same data for whichever is the current default route.

    • LinkX-Active: indicates whether the current default route is accessbile.
    • LinkX-ActiveLink: indicates which interface is the active one.
    • LinkX-CallUpTime: length of time that the current data call has been in place.
    • LinkX-IPAddress: the ip address of the active link.
    • LinkX-State: state of the interface port of the active link.
    • LinkX-Up: if the current active link is connected.

    VPN Stats

    • IPsecVPNTunnel: if the VPN tunnel is up or not.
    • IPsecVPNTunnelUpTime: how long the VPN tunnel has been up for.

    GPS Stats

    • GPS AntennaStatus: the status of the GPS antenna. Possible values are OK, Unknown, Open circuit, Short circuit.
    • GPS Location-heading: the direction of travel relative to true north. Expressed in degrees.
    • GPS Location-latitude / GPS Location-longitude: the gateway’s current GPS coordinates at time of reporting.
    • GPS Location-miles: the miles traveled on a given day. This stat reset once in 24 hours. The time of reset is configurable.
    • GPS Location-speedmph: 2D speed, in meters per hour at the time of the reporting.
    • GPS Location-zone: zone in which the gateway is located. Zone is a predefined region defined in the AMM.
    • GPS Satellites In Use: indicates whether there are sufficient satellites currently in use to support a particular fix-dimension (2 or 3).
    • GPSFix: the time since the last GPS fix.

    Stat FAQs

    • What does “LinkX-ActiveLink” mean?

      “LinkX-ActiveLink” is the active WAN link that AMM is tracking.

    • What is the purpose of LinkX?

      LinkX allows a threshold to be set on the WAN active link, irrespective of whether it is on WiFi or potentially on different cell links.
