To define a rule that adds a location to the Port Speed Change event
In Entuity, events include a standard set of attributes, e.g. source, name, severity. Please see this article for further information on the standard event attributes.
You can add additional attribute information to the event and store it in the database. The below example demonstrates how to add additional information to the event by adding a location to the Port Speed Change event. It involves the following stages:
- creation of a Pre Storage Generic processing stage and rule.
- Event Type Test matching on the Port Speed Change event type.
- a new database attribute to hold the location of a port.
- Groovy script that navigates the Entuity type hierarchy to identify a port's location, through attributes held against its device:
