The Services Config view > Advanced tab of an ESA service enables you to configure advanced settings. In the Advanced view, you can configure advanced settings to improve performance, to preserve events for rules with multiple events, to buffer events in memory, and to set the number of events to be stored on the ESA.
This workflow shows the overall process for configuring ESA. It also shows where configuring advanced settings is located in the process.
In NetWitness Platform 11.2 and earlier, ESA has two services, the Event Stream Analysis service (ESA Correlation Rules) and the Event Stream Analytics Server service (ESA Analytics). The first four procedures shown pertain to configuring the Event Stream Analysis service:
- Add Data Source to ESA Service
- Configure Notifications
- Download Live Content
(Optional) Configure Advanced Settings*
The last procedure is separate from the others and pertains to creating mappings for the ESA Analytics services to start automatically detecting advanced threats:
- (Optional) Create and Deploy ESA Analytics Mappings
*You can complete these tasks here (that is in the Services Config view Advanced tab).
- See "Add or Update a Host" in the Host and Services Getting Started Guide
