The rule management module provides interfaces for the operations (e.g. creating, updating and deleting) on the rules. -The data source adapter consists of subscribers and publishers, which are used to convert the data format into the one that could be digested by Holmes and vice versa. +The data source adapter consists of subscribers and publishers, which are used to convert the data format into the one that could be digested by Holmes and vice versa. The engine management module is the core of Holmes. All the rules are deployed here. When alarms gets into Holmes, they will be pushed into the Drools engine and analyzed by the enabled rules one after another. When processing the alarms, a couple of attributes, such as the alarm name, the occurrence time of the alarm and so on, are utilized. Also, the topological information from A&AI is used in combination of the alarm attributes. After the root cause is identified, it will be converted into a control loop event and published to a specific DMaaP topic which is subscribed to by the Policy component. |
