Lesson 1Config Management Database (CMDB) concepts and mapping to inventory fieldsDis section introduce CMDB concepts and explain how inventory fields map to configuration items, relationships, and service models, enabling consistent data flows between operational inventory and broader IT service management.
Configuration items and CI classesMapping inventory hosts to CIsModelling relationships and dependenciesSynchronising CMDB and inventory dataGovernance and data quality controlsLesson 2Integration patterns: linking inventory to ticketing, monitoring, and backup systemsDis section show how to integrate inventory data with ticketing, monitoring, and backup platforms, ensuring consistent identifiers, automated updates, and reliable context for incidents, alerts, and recovery operations across de environment.
Linking inventory records to ticketsSharing inventory with monitoring toolsAligning backup jobs with inventory dataUsing inventory IDs across all systemsAPIs and webhooks for data synchronisationLesson 3Concise summary of the on-premises and cloud infrastructureDis section explain how to summarise on-premises and cloud infrastructure, creating high-level views of capacity, platforms, and critical services dat remain grounded in detailed inventory data but are consumable by stakeholders.
Building environment overview dashboardsAggregating by site, platform, and tierHighlighting critical and shared servicesReporting capacity and utilisation trendsPresenting summaries to stakeholdersLesson 4Inventory attributes: hostname, FQDN, IP addresses, MAC, OS/version, kernel, roles, services, installed packages, virtualization hostDis section define core technical attributes every system record must include, explaining how identifiers, networking data, OS details, and workload roles combine to create a uniquely traceable and supportable inventory entry.
Hostnames and FQDN naming standardsIP and MAC address tracking practicesRecording OS, kernel, and build versionsDocumenting system roles and key servicesTracking installed packages and softwareFlagging virtualization hosts and clustersLesson 5Routine inventory updates: automated schedules, change hooks from config management, and audit checksDis section describe how to keep inventory current using scheduled scans, change hooks from configuration management, and periodic audits, emphasising reconciliation, exception handling, and reporting on data freshness.
Scheduled discovery and refresh cyclesHooks from deployment and config toolsDetecting drift and orphaned recordsAudit procedures and sampling methodsData freshness and completeness metricsLesson 6Methods to build inventory: automated discovery using SSH/WMI/agents and example queriesDis section cover automated discovery methods using SSH, WMI, and agents, including credential strategies, security considerations, and example queries dat collect accurate, repeatable inventory data with minimal manual effort.
Agentless discovery with SSH and WMIUsing configuration management factsDesigning lightweight inventory agentsExample queries for OS and hardwareCredential management and securityLesson 7Inventory attributes: physical location, rack, datacenter, cloud region, subnet, VLANDis section focus on location and network context, explaining how to record datacenter, rack, cloud region, subnet, and VLAN details so teams can troubleshoot connectivity, plan capacity, and understand physical and logical placement.
Datacenter, room, and rack identifiersCloud regions, zones, and placementsSubnets, VLANs, and segment mappingDocumenting cross-site dependenciesUsing location data for incident impactLesson 8Inventory attributes: dependencies, upstream/downstream services, backup policy, monitoring groups, last patch dateDis section focus on dependency and lifecycle attributes, such as upstream and downstream services, backup policies, monitoring groups, and patch dates, enabling impact analysis, compliance checks, and risk assessments.
Documenting upstream and downstream flowsAssigning backup tiers and retentionGrouping systems into monitoring setsTracking last patch and update datesUsing data for risk and impact analysisLesson 9Inventory attributes: ownership, business owner, application owner, SLAs, contact info, maintenance windowDis section detail business and ownership attributes, including service owners, SLAs, contacts, and maintenance windows, showing how dem guide approvals, incident escalation, and scheduling of disruptive operational work.
Identifying business and application ownersCapturing SLAs and service tiersPrimary and on-call contact detailsDefining maintenance windows and freezesOwnership changes and review cadenceLesson 10List of system types to track: Linux distributions, Windows Server, hypervisor VMs, cloud VMs, network devicesDis section categorise de main system types dat must be tracked, highlighting differences in metadata, lifecycle, and tooling for Linux, Windows, hypervisors, cloud workloads, and network devices within a unified inventory model.
Linux distribution families and variantsWindows Server editions and rolesHypervisor hosts and guest VM recordsCloud VM instances and managed servicesNetwork devices, firewalls, and appliancesLesson 11Methods to build inventory: manual spreadsheet templates and recommended column schemasDis section cover manual inventory creation using spreadsheet templates, recommending column schemas, validation rules, and workflows dat reduce errors and ease later migration into automated or CMDB-backed systems.
