Understand how infrastructure discovery and service dependency maps help investigate outages.
Recommended structure
- IntroductionUnderstand how infrastructure discovery and service dependency maps help investigate outages.
- Discovery identifies infrastructureDiscovery identifies supported devices and applications and updates configuration records. It requires suitable network access, credentials and configuration. Define scan scope and ownership first; do not assume every asset is detected automatically without preparation.
- Mapping explains dependenciesKnowing a server exists is different from knowing which business service depends on it. A booking app may use a web server, API and database. Service Mapping relates these components to investigate the services a failure could affect.
- Start with one critical serviceValidate one service map with its owner and keep it current. Use it for alert triage and maintenance planning. Check your ServiceNow subscriptions and enabled capabilities during scoping because feature availability depends on your environment.
- ConclusionDiscovery finds components; Service Mapping adds service context.
