EventSLMEngined

Overview

The Unified Assurance Event SLM Engine leverages the configured Service Hierarchies with thresholds and meta events to generate SLM impacted events.

Event SLM Engine Setup

  1. Add Meta Events or modify existing Meta Events:

    Configuration -> Events -> Processing -> Meta Events

  2. Navigate to the SLM Service Management UI and define a service hierarchy:

    Configuration -> Service Management

    An additional example of creating a SLM service is available via the documentation:

    SLM Service Example

  3. Enable the default Service, unless a specific configuration option is needed.

    Configuration -> Broker Control -> Services
