Core concepts overview

xrelia is built around a small set of core concepts that represent the health of your systems. Understanding these concepts will help you model your infrastructure, monitor services effectively, and interpret incidents with confidence.

The xrelia model

xrelia organizes reliability intelligence around nine core resources: Platforms, Services, Service instances, Health checks, User journey (synthetic requests), Metrics, Dependencies, Changes, and Incidents.

Core resources

Option	Description
Platforms	Production, staging, preview
Services	Applications and components
Instances	Specific deployments of a service on a platform
Health checks	Direct availability probes
User journey	Synthetic request checks and monitoring
Metrics	Performance and resource data
Dependencies	Internal and external relationships
Changes	Deployment or configuration modifications affecting a service instance
Incidents	Correlated operational events
