Network management apparatus, network management method and network management system

A network management method performed by a network management apparatus, comprising steps of:

• acquiring correlating information that correlates an error that may occur when executing a workflow to a way of resolving the error, the workflow defining a series of network construction processes consisting of a plurality of processes;
• collecting logs related to executing the workflow;
• stopping executing the workflow when an error occurs during the workflow being executed;
• during the workflow being stopped, referring to the correlating information based on the logs and determining a handling to deal with the error to perform the handling;
• and
• resuming, when the error is resolved by performing the handling, the workflow from a process corresponding to the handling among the plurality of processes.

A network management system, comprising:

• at least one memory configured to store program code;
• and
• electronic circuitry including at least one processor, the at least one processor being configured to read and operate according to the program code to:
• store correlating information that correlates an error that may occur when executing a workflow to a way of resolving the error, the workflow defining a series of network construction processes consisting of a plurality of processes;
• collect logs related to executing the workflow;
• stop executing the workflow when an error occurs during the workflow being executed;
• during the workflow being stopped, refer to the correlating information based on the logs and determine a handling to deal with the error to perform the handling;
• and
• resume, when the error is resolved by the handling, the workflow from a process corresponding to the handling among the plurality of processes.
