Chapter 2. How data and application security are handled in Red Hat Lightspeed

A data collector is an application or service that regularly sends host information, updates, or system profile data to Red Hat Lightspeed inventory. insights-client is a data collector for Red Hat Lightspeed.

System facts are the metadata that data collectors collect about your RHEL systems. These facts describe runtime configuration, system health, and system performance. insights-client uses the system facts it collects to populate inventory data in Red Hat Lightspeed and to update existing data. Red Hat Lightspeed also uses system facts to analyze system performance and to create recommendations for services such as Advisor or remediations.
