CIS-DF--Day7 CMDB Workspace Deep Dive

🔑 Core CMDB Concepts 1. Three Pillars of CMDB Ingestion How data enters ServiceNow Sources include: Discovery Service Mapping Integration Hub Agents Service Graph Connectors APIs, Imports, Wizards, Mid Servers Governance (Data Health) Ensures data remains accurate and reliable over time Handles reconciliation, duplication, lifecycle management Insights Uses governed data to improve: IT Operations Automation Planning Costing Application & Service visibility 🧠 Ingestion & Reconciliation Identification & Reconciliation Engine (IRE) Core engine that decides: Which source is trusted How CI uniqueness is determined Which records to update or reject Uses Identification Rules (e.g., serial number, name, asset tag) 🏗️ CMDB Workspace (Central Hub) Acts as a single-stop shop for CMDB management Covers: CI creation Reconciliation (IRE) Health monitoring Insights and dashboards No extra plugin needed for basic workspace Workspace Tabs: Home Intelligent Search (NLQ – Natural Language Query) CI overview & recent CI trends My Work Deduplication tasks Attestation & certification tasks CMDB 360 Multi-source CI visibility (requires plugins & property enablement) Insights Adoption rate of CMDB features Recommendations to improve usage Management Governance & configuration controls ✅ CMDB Health – The 3C Model CMDB health is measured using three parameters: Completeness Required fields are populated Correctness Data values are valid and meaningful Compliance CI meets defined governance rules Important Points: Health metrics are job-driven Jobs typically run daily (can be triggered manually) Health rules are configured in Class Manager Required vs Recommended fields must be explicitly defined 🔄 Governance Activities Deduplication Tasks Created when multiple data sources create duplicate CIs Attestation / Certification Tasks Periodic validation of records by owners or managers Data Manager Used for governance enforcement Customizing health rules is NOT considered risky customization 📊 Insights & Adoption Dashboard ServiceNow provides an Adoption Blueprint Shows how effectively CMDB features are used Adoption score increases as you enable: Query Builder CMDB Dashboards Data Manager Multi-source data Discovery & Integrations Plugin installation and system properties can raise adoption to 100% 🧩 Services vs CIs – Key Understanding ServiceNow instance itself is NOT a CI CI = Infrastructure components (servers, DBs, clusters) Service / Application Service What customers actually consume (e.g., Email, ADP Payroll) Users raise incidents on services, not underlying hardware 🎯 Key Takeaways CMDB is not just about storing data—it’s about continuous data quality Everything in ServiceNow is configured, not automatic CMDB Workspace is critical for: Exams (20–30 questions) Real-world consulting work Clear distinction between: Business Application Application Service Infrastructure CI is essential for successful CMDB implementation
