What is Culprit Locator
Culprit Locator (or root-cause finder) is a set of ELK-based dashboards created based on ONAP logs to identify where within a failed flow that a problem originated in the most efficient and effective way. The intention is that this would be able to help the testers, developers, and developers operations to get issues from identification to diagnosis/fix more quickly. This application demonstrates how the traceable logs can be used to enhance troubleshooting efforts for the testers, developers and developersoperations. The current version is based on explicit ERROR logs to quickly locate the problem sources in terms of components or subcomponents or a series of significant log details.
