TECHNIQUE FOR SUPPORTING FINDING OF LOCATION OF CAUSE OF FAILURE OCCURRENCE
First Claim
1. A support system for supporting finding of a location of a cause of a failure occurrence in an information system that includes a plurality of components, comprising:
- a storage unit for storing a dependency graph in which components are expressed as nodes and relationships of components depending directly on each other are expressed with links;
a log display unit for displaying, in response to detection of a failing component, a log of events occurring in the component;
a selection unit for selecting, in response to an instruction by a user, a component that is adjacent to the failing component on the dependency graph, as a candidate component for a failure cause; and
a display control unit for enabling the log display unit to additionally display a log of events occurring in the selected candidate component;
wherein the selection unit further selects, in response to an instruction by a user, a component that is adjacent to the candidate component on the dependency graph as a new candidate component, on condition that a log thereof has not yet been displayed.

Abstract
A support system includes a storage unit for storing a dependency graph in which components are expressed as nodes and relationships of components depending directly on each other are expressed with links, a log display unit for displaying, in response to detection of a failing component, a log of events occurring in the component, a selection unit for selecting, in response to an instruction by a user, a component that is adjacent to the failing component on the dependency graph, as a candidate component for a failure cause, and a display control unit for enabling the log display unit to additionally display a log of events occurring in the selected candidate component, wherein the selection unit further selects, in response to an instruction by a user, a component that is adjacent to the candidate component on the dependency graph as a new candidate component on condition that a log thereof has not yet been displayed.

10. A method for supporting finding of a location of a cause of a failure occurrence in an information system that includes a plurality of components, comprising the steps of:
-
storing a dependency graph in which components are expressed as nodes and relationships of components depending directly on each other are expressed with links; displaying, in response to detection of a failing component, a log of events occurring in the component; selecting, in response to an instruction by a user, a component that is adjacent to the failing component on the dependency graph, as a candidate component for a failure cause; displaying a log of events occurring in the selected candidate component; selecting, in response to an instruction by a user, a component that is adjacent to the candidate component on the dependency graph as a new candidate component, on condition that a log thereof has not yet been displayed; and further displaying a log of events occurring in the selected candidate component.

11. A computer program product comprising computer program code recorded on a computer-readable recording medium, for causing an information processing system to serve as a support system for supporting finding of a location of a cause of a failure occurrence in an information system that includes a plurality of components, the program causing the information processing system to function as:
-
a storage unit for storing a dependency graph in which components are expressed as nodes and relationships of components depending directly on each other are expressed with links; a log display unit for displaying, in response to detection of a failing component, a log of events occurring in the component; a selection unit for selecting, in response to an instruction by a user, a component that is adjacent to the failing component on the dependency graph, as a candidate component for a failure cause; and a display control unit for enabling the log display unit to additionally display a log of events occurring in the selected candidate component; wherein the selection unit selects, in response to an instruction by a user, a component that is adjacent to the candidate component on the dependency graph, as a new candidate component, on condition that a log thereof has not yet been displayed.
