        description:
            - >-
                Action to perform when the response to an inline monitor (a monitor of type C(HTTP-INLINE)) indicates
                that the service is down. A service monitored by an inline monitor is considered C(DOWN) if the response
                code is not one of the codes that have been specified for the Response Code parameter.
            - "Available settings function as follows:"
            - >-
                * C(NONE) - Do not take any action. However, the show service command and the show lb monitor command
                indicate the total number of responses that were checked and the number of consecutive error
                responses received after the last successful probe.

            - >-
                * C(DOWN) - Mark the service as being down, and then do not direct any traffic to the service until the
                configured down time has expired. Persistent connections to the service are terminated as soon as the
                service is marked as C(DOWN). Also, log the event in NSLOG or SYSLOG.

    respcode:
        description:
            - >-
                Response codes for which to mark the service as UP. For any other response code, the action performed
                depends on the monitor type. C(HTTP) monitors and C(RADIUS) monitors mark the service as C(DOWN), while
                C(HTTP-INLINE) monitors perform the action indicated by the Action parameter.

                Calculate the least response times for bound services. If this parameter is not enabled, the
                appliance does not learn the response times of the bound services. Also used for LRTM load balancing.

        description:
            - >-
                Time value added to the learned average response time in dynamic response time monitoring (DRTM).
                When a deviation is specified, the appliance learns the average response time of bound services and
                adds the deviation to the average. The final value is then continually adjusted to accommodate
                response time variations over time. Specified in milliseconds, seconds, or minutes.

            - >-
                Note: For C(UDP-ECV) monitors for which a receive string is not configured, response timeout does not
                apply. For C(UDP-ECV) monitors with no receive string, probe failure is indicated by an ICMP port

                Response time threshold, specified as a percentage of the Response Time-out parameter. If the
                response to a monitor probe has not arrived when the threshold is reached, the appliance generates an
                SNMP trap called monRespTimeoutAboveThresh. After the response time returns to a value below the
                threshold, the appliance generates a monRespTimeoutBelowThresh SNMP trap. For the traps to be
                generated, the "MONITOR-RTO-THRESHOLD" alarm must also be enabled.

                Retries parameter is set to 6, out of the ten probes sent, at least six probes must fail if the
                service is to be marked as DOWN. The default value of 0 means that all the retries must fail if the

    destip:
        description:
            - >-
                IP address of the service to which to send probes. If the parameter is set to 0, the IP address of
                the server to which the monitor is bound is considered the destination IP address.

    destport:
        description:

                TCP or UDP port to which to send the probe. If the parameter is set to 0, the port number of the
                service to which the monitor is bound is considered the destination port. For a monitor of type C(USER),
                however, the destination port is the port number that is included in the HTTP request sent to the
                dispatcher. Does not apply to monitors of type C(PING).

                State of the monitor. The C(disabled) setting disables not only the monitor being configured, but all
                monitors of the same type, until the parameter is set to C(enabled). If the monitor is bound to a
                service, the state of the monitor is not taken into account when the state of the service is
                determined.

    transparent:
        description:
            - >-
                The monitor is bound to a transparent device such as a firewall or router. The state of a transparent
                device depends on the responsiveness of the services behind it. If a transparent device is being
                monitored, a destination IP address must be specified. The probe is sent to the specified IP address
                by using the MAC address of the transparent device.

    iptunnel:
        description:
