    Study Notes

    Configuration Items (CIs)

    • Configuration Item (CI) is any physical or logical component that needs management for delivering a product/service, like servers or applications.
    • Attributes define CIs further, including features like name, serial number, and operating system.
    • Relationship Types establish connections between CIs, such as an application depending on a database.

    CI Classifications

    • CI Classes categorize CIs sharing common attributes (e.g., Windows Server, Database).
    • CI Reclassification occurs when the class of a CI changes, affecting its properties.
    • CI Class Upgrade and Downgrade modify the specificity of a CI’s classification, impacting its attributes.

    Configuration Management Systems

    • Configuration Management Database (CMDB) holds configuration records throughout their lifecycle, maintaining essential CI attributes and relationships.
    • Configuration Management System (CMS) utilizes tools and databases for managing configuration data.

    Asset Management

    • Hardware assets and CIs connect through their lifecycle; each asset creation often leads to a corresponding CI.
    • Asset DB focuses on inventory and financial data, while CMDB emphasizes inventory and relationships.

    Data Integrity and Management

    • Stakeholders are crucial for defining CI requirements and ensuring organizational support during CMDB implementation.
    • Identification and Reconciliation rules maintain data integrity amidst multiple sources by validating updates and preventing duplicates.

    CMDB Health and Governance

    • CMDB Health Dashboard evaluates data quality using scores for completeness, correctness, and compliance.
    • Effective governance structures and team building are vital for sustaining the configuration management process and fostering long-term trust.

    Discovery and Data Population

    • Discovery involves identifying and classifying infrastructure components, with phases including Scan, Classify, Identity, and Explore.
    • Accurate data population is facilitated by agent-less auto-discovery and integrations with various data sources.

    Role of Auditing

    • Auditing types, like Compliance and Desired State audits, help validate CI data and maintain effectiveness.
    • Health Inclusion Rules guide computations for the CMDB Health Dashboard, ensuring only pertinent CIs are assessed.

    Metrics and Reporting

    • Metrics such as Duplicate and Orphan counts help gauge CMDB data quality and highlight issues within CI management.
    • Compliance Scorecard results arise from various audit types, with Desired State audits presenting the most accessible configuration results.

    Technical Operations

    • Integration with tools like SCCM for CI import updates involves specific configurations and identifiers like Correlation ID.
    • Parameters for discovering virtual machines (VMs) encompass VMware Credentials, MID Server, and access control measures.

    Common Services Data Model (CSDM)

    • CSDM provides a consistent framework of service-related definitions to enhance reporting and service modeling across the ServiceNow platform.

    Summary of CI Management Strategies

    • Configuration management should always start with clear goals, including what to track (CIs), method of management, rationale, and measures of success.
    • Standard roles within configuration management, like Configuration Manager and System Analyst, delineate responsibilities and oversight in managing CIs.

    Challenges in CI Identification

    • Duplicate CIs arise from ineffective identification rules, necessitating precise identifier criteria for clarity.
    • Overloaded CIs occur when multiple CIs are incorrectly identified as one, indicating a need for stringent classification methods.

    Final Insights

    • The relationship between assets and CIs is essential for managing financial and operational workflows effectively within the organization.
    • Understanding CI classes and relationships enables more efficient discovery and management within the CMDB framework.### Duplicate and Staleness Metrics
    • The Duplicate metric is linked to a CMDB Group specifically for the Server class.
    • Stale CIs are identified as those not updated within a predefined time frame, implying potential outdated data.

    Orphan and Staleness Rules

    • Orphan rules are defined based on specific attributes and relationships; a CI can be labeled as orphan if it lacks an owner or asset.
    • The number of orphan rules in a base system is contingent on the enabled plugins.

    Reclassification Behaviors

    • Reclassification involves changing a CI's class; it can lead to data loss, particularly during downgrade or switch actions.
    • Reclassifying from a higher to a lower class is termed Downgrade, while the opposite is known as Upgrade.

    Effective Duration and Health Metrics

    • The default Staleness rule is set to a duration of 60 days.
    • Health Metrics require specific configurations, including rule definition and task creation enablement.

    Duplicate CI Detection and Management

    • Duplicate CIs are identified during the identification and reconciliation processes, utilizing tools like the Duplicate CI Remediator for resolution.
    • The Master CI is retained actively while considering retirement or deletion of other duplicates.

    Remediation Workflow

    • Remediation workflows are referenced from CMDB Remediation Rules, allowing for task initiation that follows specific remediation procedures.

    CI Query Types

    • CMDB Query Builder enables intricate infrastructure and service queries across multiple classes with various relationships.
    • Service Mapping Queries necessitate the activation of Service Mapping, linking applications to their respective technical services.
    • Combination Queries blend Service Mapping and CMDB Queries for comprehensive insights into the CI landscape.
