Abstract
A network monitor system uses status programs to recurrently monitor the operational status of subsystems of a communication network. When a nonnormal response is received from a status program a user-specified associated repair program is enabled to repair the malfunction. An internal table recurrently derived from a user-defined table specifies when the various status programs should be executed. The system enables the user or administrator to update the user-defined table at any time.
Claims16
A network monitor system for use in a communication network, said network monitor system comprising
- a plurality of status programs for determining an operating status of a plurality of subsystems of the network, while the network is active providing communication services using said subsystems, one or more status programs including one or more changeable test parameters for indicating a normal status of said subsystems of the network, said test parameters being changeable without disabling the operation of either said network monitor system or said subsystems,
- at least one repair program for automatically repairing a non-normal status of an associated one or more subsystems said repair program automatically performing its repair operation on said non-normal subsystems without disabling the operations of either said network monitor system or said non-normal subsystems,
- means for recurrently executing, under system control, one or more of said status programs and responsive to said non-normal status returned from the one or more of said status programs for automatically enabling said associated at least one repair program.
A network monitor system for use in a communication network comprising
- a first group of status programs for determining operating statuses of subsystems used to control the network, while said network is active providing communication services, one or more status programs including one or more use-specified changeable test parameters for determining a normal status of an associated operating subsystem, said test parameters being changeable without disabling the operation of either said network monitor system or said subsystems,
- a second group of repair programs for automatically repairing a non-normal status of an associated operating subsystem, said repair programs operating automatically without disabling the operations of either said non-normal subsystems or said network monitor system,
- a table including said first group of status programs and associating therewith said second group of repair programs, and
- means for accessing said table recurrently, under network monitor system control, to perform one or more status programs and for automatically enabling an associated one or more repair programs when a non-normal status response is returned from said one ore more status programs.

A communication network comprising
- a plurality of subsystems for providing communication services of said network, and
- a network monitor system including
- a first group of status programs for determining operating statuses of said subsystems, while said subsystems are active providing communication services of said network, each status program including one or more user-specified changeable test parameters for indicating the status of an associated subsystem, said test parameters being changeable without disabling the operation of either said network monitor system or said subsystems, and
- at least one repair program for automatically repairing a non-normal status of an associated subsystem, said at least one repair program operating automatically without disabling the operations of either said non-normal subsystem or said network monitor system,
- means for recurrently executing a status program, under a status program control, and responsive to a non-normal status returned from said status programs for automatically enabling said associated at least one repair program.

A method of operating a network monitor system for use in a communication network comprising the steps of
- determining an operating status of the network using one ore more of a plurality of status programs, which are system activated on a recurrent basis while said network is active providing communication services, one ore more status programs including one or more user-specified changeable test parameters for indicating a normal status of a subsystem of said network, said test parameters being changeable without disabling the operation of either said network monitor system or said subsystems, and
- automatically enabling at least one associated repair program for repairing a determined non-normal operating status of an associated one or more subsystems, said at least one associated repair program automatically performing its repair operation on said non-normal subsystems without disabling the operations of either said network monitor system or said non-normal subsystems of said network.
