Network Management Implementation
The organization should have an implemented network management system that is able to detect the defined
threshold values and report on the values for specified time periods. Use a RMON network management
system that can archive threshold messages in a log file for daily review or a more complete database solution
that allows searches for threshold exceptions for a given parameter. The information should be available to the
network operations staff and manager on a continuous basis. The network management implementation
should include the ability to detect software/hardware crashes or tracebacks, interface reliability, CPU, link
utilization, queue or buffer misses, broadcast volume, carrier transitions, and interface resets.

Network Operations Metrics
A final area of proactive fault management that overlaps with performance management is network operations
metrics. These metrics provide valuable data for fault management process improvement. At a minimum,
these metrics should include a breakdown of all problems that occurred during a given period. The breakdown
should include information such as:
metrics. These metrics provide valuable data for fault management process improvement. At a minimum,
these metrics should include a breakdown of all problems that occurred during a given period. The breakdown
should include information such as:
Number of problems that occur by call priority
•
Minimum, maximum, and average time to close in each priority
•
Breakdown of problems by problem type (hardware, software crash, configuration, power, user error)
•
Breakdown of time to close for each problem type
•
Availability by availability group or SLA
•
How often you met or missed SLA requirements
•
The help desk often has a reporting system with the ability to generate metrics or reports. Another means to
gather this data is the use of an availability monitoring tool. Overall metrics should be made available on a
monthly basis. Process improvement based on the discussion should be implemented in order to improve
missed service level agreement requirements or in order to improve how certain problem types are handled.

Performance Management Indicators
Performance indicators provide the mechanism by which an organization measures critical success factors.
Document the Network Management Business Objectives
This document could be a formal concept of operations for network management or a less formal statement of
required features and objectives. However, the document should assist the network manager as they measure
success.
required features and objectives. However, the document should assist the network manager as they measure
success.
This document is the organization network management strategy and should coordinate the overall business
(nonquantitative) goals of network operations, engineering, design, other business units, and the end users.
This focus enables the organization to form the long range planning activities for network management and
operation, which includes the budgeting process. It also provides guidance for the acquisition of tools and the
integration path required to accomplish the network management goals, such as SLAs.

This strategic document cannot focus too narrowly on the management of specific network problems, but on
those items important to the overall organization, which include budgetary issues. For example:

Identify a comprehensive plan with achievable goals.
•
Identify each business service/application that require network support.
