Abstract: Visibility of a message transmitted from a maintenance object system is improved. A maintenance person support device 1 includes: a storage device 10 configured to store distribution rule data 11 in which a category of a message received from a processing unit 2 and an action name of an action corresponding to the message are associated with each other, and action definition data 12 in which the action name and a channel corresponding to the category as execution contents of the action are associated with each other; a message transmission/reception unit 21 configured to receive a message from the processing unit 2; an action execution unit 22 configured to acquire the action name corresponding to the category of the message from the distribution rule data 11 and acquire the execution contents corresponding to the acquired action name from the action definition data; and a user interface control unit 23 configured to display the message to the channel specified by the acquired execution contents.

Abstract: Provided is a service graph analysis device 10 which detects anomalies of a monitored service 100 that implements specific features by a chained operation of multiple components. The service graph analysis device 10 includes an extraction unit 11 configured to extract a processing start event and a processing end event from monitoring data and generate a firing sequence arranging the events in chronological order, the monitoring data including information on a series of processing in the monitored service 100; and a detection unit 12 configured to determine whether the event arranged in the firing sequence can be fired in a service graph illustrating a dependency between components constituting the monitored service 100, and detect anomalies in a case where there is a non-fired event.

Abstract: Provided is a service graph generation apparatus 10 for generating a service graph expressing a dependency relationship between components constituting a monitoring target service 50. The service graph generation apparatus 10 includes an acquisition unit 11 that acquires trace data including spans recording a parent-child relationship and time data of processing of components in a series of processing in a service, an analysis unit 13 that compares, for every piece of the trace data, time data between spans of the components having the same parent to estimate an order relationship or an exclusive relationship between the components, and a creation unit 14 that creates a service graph expressing all components formed of the monitoring target service 50, and the parent-child relationship, the order relationship, and the exclusive relationship between the components.

Abstract: An agent device 1 of a monitoring system 5 includes: an acquisition unit 22 that sequentially acquires monitored values from a processing unit 21; a removal unit 23 that generates denoised monitored values by removing noise from the monitored values; and a transmission unit that transmits the denoised monitored values to a manager device 2. The manager device 2 includes a determination unit 62 that determines the monitoring interval, at which monitored values are acquired from the agent device 1, by referencing the denoised monitored values acquired from the agent device 1.

Abstract: Provided is a control device 10 for controlling an operation phase of a maintenance control system, wherein the system performs maintenance on a monitored service 100 implementing specific features by means of a chained operation of multiple components using a service graph illustrating a dependency between components constituting the monitored service 100. The control device 10 includes an acquisition unit 11 configured to acquire update information of the monitored service 100, a determination unit 13 configured to determine update convergence of the service graph, and a control unit 12 configured to shift the operation phase to a learning phase in which the service graph is updated when the update information has been received, and shift the operation phase to a detection phase in which anomalies are detected using the service graph when it is determined that the update of the service graph has converged.
