    OptionDescription

    Health check

    Click to enable health check for monitoring the gateway and specify the parameters based on the description shown below.

    Interval (in seconds)

    Specify the time interval in seconds after which the health should be monitored.

    Acceptable range: 5 to 65535 seconds

    Default: 60 seconds

    Timeout (in seconds)

    Specify the time interval in seconds within which the gateway must respond.

    Acceptable range: 1 to 10 seconds

    Default: 2 seconds

    Retries

    Specify the number of tries to probe the health of the gateway, after which the gateway will be declared unreachable.

    Acceptable range: 1 to 10

    Default: 3

    Monitoring condition

    Protocol: From the drop-down list, select the communication protocol, such as TCP or PING (ICMP). Select the protocol depending on the service to be tested for the gateway’s health.

    Port: For TCP communication, specify the port number for communication.

    IP address: Specify the IP address of the computer or the network device which is permanently running or most reliable.

    Operator:

    • AND - All the conditions must be satisfied for the gateway to be considered alive.
    • OR - At least one condition must be satisfied for the gateway to be considered alive.

    A protocol request is sent to the given IP address. If the IP address does not respond to the request within the time-out interval then given number of retries are attempted. If it still does not respond then the device considers the IP address as unreachable.
