Overview
ISO/IEC 10164-4:1992/Cor 2:1999 is an international standard developed by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC). It provides a technical corrigendum to the ISO/IEC 10164-4:1992 standard, which defines the alarm reporting function within Systems Management as part of Open Systems Interconnection (OSI). This technical corrigendum clarifies and amends specific aspects of alarm reporting, an essential function for effective network management in information technology environments.
As part of the broader OSI Systems Management framework, the alarm reporting function ensures reliable event notification and problem detection across open and interoperable systems. The corrigendum was prepared by Joint Technical Committee ISO/IEC JTC 1, focusing on adjustments that enhance the effectiveness and clarity of alarm notifications and their resolution.
Key Topics
- Alarm Reporting Function: The standard addresses mechanisms for generating, transmitting, and clearing alarms in distributed networked systems.
- Severity Level - Cleared: Clarifies the "cleared" severity level, specifying how previously reported alarms are marked as resolved or cleared within management systems.
- Parameters for Alarm Clearing:
- Managed object
- Event type
- Probable cause
- Specific problems
- Correlated notifications
- Alarm Correlation: Details how correlated notifications and problem parameters interact to define which alarms are to be cleared.
- Interoperability: Reinforces compatibility with related ITU-T Recommendations (specifically ITU-T Rec. X.733).
Applications
Implementing the ISO/IEC 10164-4:1992/Cor 2:1999 corrigendum provides significant benefits in:
- Network Management Systems (NMS): Enhances an IT manager's ability to monitor, detect, and respond to fault conditions within enterprise networks by delivering clear alarm reporting and resolution procedures.
- Telecommunications: Supports telecommunication operators with standardized methods for alarm generation and clearance, improving fault isolation and recovery.
- IT Service Management: Enables organizations to maintain high service reliability by ensuring alarms are accurately reported and promptly cleared, minimizing downtime and service disruption.
- Vendor Interoperability: Promotes the use of standardized alarm reporting methods between different vendors’ network components and management systems, fostering vendor-neutral integration.
Related Standards
- ISO/IEC 10164-4:1992: Foundation standard for Systems Management - Alarm Reporting Function, detailing how alarms are defined, reported, and managed in OSI environments.
- ITU-T Recommendation X.733: Closely related specification that harmonizes alarm reporting requirements for telecommunication and data networks.
- ISO/IEC 10040: Establishes the Systems Management framework for OSI, within which alarm reporting is a critical function.
- Other Corrigenda/Amendments: Updates and corrections to OSI Systems Management standards ensure consistency and relevance as network technologies evolve.
By adhering to ISO/IEC 10164-4:1992/Cor 2:1999, organizations achieve robust, standardized alarm reporting practices that enhance network reliability and management effectiveness in complex, heterogeneous IT environments.
