Network management is a service that makes use of a variety of tools, devices and applications to assist network managers in the maintenance and monitoring of large-scale computer and telecommunications networks.
The network management tools assist you in simplification, automation, and integration of the network to reduce the over all operational costs and improving productivity.
Network management is execution of a set of functions required for controlling, planning, allocating, deploying, coordinating, and monitoring network resources, including performing functions such as:
Gathering network elements Data Storage Analysis and Prediction Configuration and control of network elements Performance and system planning management Initial Network Planning Frequency Allocation Cryptographic Key Distribution Authorization Configuration Management Fault Management Security Management Performance Management Bandwidth Management Accounting Management
Key Features of Network Management:
> A cost-effective, open source solution integrating with other leading open source tools. > Visibility into the availability and performance of entire infrastructure > Easy and cost-efficient to deploy and maintain > A single point of access for consolidated information from monitoring systems > Helps network administrators track machine uptime, outage and usage information so they can keep their operations healthy
Network elements such as interfaces on switches and routers Services which network resources provide such as web pages, database access, DNS, DHCP, etc.

Monitoring of network services (SMTP, POP3, HTTP, NNTP,PING, etc.) Monitoring of host resources (processor load, disk and memory usage, running processes, log files, etc.) Monitoring of environmental factors such as temperature. Ability to define network host hierarchy, allowing detection of and distinction between hosts that are down and those that are unreachable Contact notifications when service or host problems occur and get resolved (via email, pager, or other user-defined method) Optional escalation of host and service notifications to different contact groups Ability to define event handlers to be run during service or host events for proactive problem resolution Support for implementing redundant and distributed monitoring servers External command interface that allows on-the-fly modifications to be made to the monitoring and notification behavior through the use of event handlers, the web interface, and third-party applications Retention of host and service status across program restarts Scheduled downtime for suppressing host and service notifications during periods of planned outages Ability to acknowledge problems via the web interface Web interface for viewing current network status, notification and problem history, log file, etc. Simple authorization scheme that allows you restrict what users can see and do from the web interface
