When flow data of flow is to be downloaded from a flow template manager to a flow editor, a system receives a first request to deploy an external service corresponding to an invoke node in the flow, and transmits a second request to deploy an external service identified by the first request to a service deployment manager associated with a site corresponding to the external service. The service deployment manager deploys an external service identified by the second request on a service execution platform at the site, and returns a response associated with an invocation destination end point corresponding to the external service. The system returns a first response associated with an invocation destination end point set to a property of the invoke node by the flow template manager to a transmission source of the first request.

A management apparatus executes: receiving from a given communication apparatus where a fault has occurred, fault information; selecting a given flow that passes through the given communication apparatus from among a group of flows on the basis of the identification information of the given communication apparatus included in the fault information; determining whether the communication pattern of the given flow is similar to the given time series data indicating the change over time of the traffic within a period from a set period prior to the fault occurrence date and time to the fault occurrence date and time for the given flow; calculating the certainty that the given flow has been transmitted on the fault occurrence date and time on the basis of a frequency of appearance of the traffic of the communication pattern determined to be similar; and outputting calculation results.

Management apparatus, management method, and recording medium

A management system constructs management information indicating that log chunks and issue chunks extracted from a first system managing log information and issue information output by a process related to a first team for a program to be developed are linked. The management system searches, from the management information, a log message group compatible with a designated log message group that is one or more log messages related to the issue by log pattern matching using the designated log message group in a case of receiving an inquiry with which the designated log message group is associated from the second system. The management system displays, on the second system, a response containing a handling method represented by handling method information corresponding to the found log message group.
