What do network monitoring software systems do and why are they important? Show
Network monitoring software is designed to provide automated support for some or all of the network management functions. Network monitoring software systems are used to perform some of the functions of monitors and analyzers, identify errors, run diagnostic tests, monitor an entire network, compile statistics, and prepare real-time management reports. Network monitoring software systems are important because they signify improved or deteriorating conditions. There are dozens of network management tools available. Some software tools support configuration management, some support performance and fault management, while some attempt to do both. Some tools have modules to support the help desk providing end user support. Network Monitoring Tools TypesThere are three fundamentally different types of network management software.
These data can be sent to the network manager’s computer when the device receives a special control message. If the device detects a critical situation it can send a special control message (called an alarm) to the network manager’s computer. The two most commonly used network management protocol standards are SNMP and CMIP. What is the Simple Network Management Protocol (SNMP)? The simple network management protocol (SNMP) originally was developed to control and monitor the status of network devices on TCP/IP networks, but now it is available for other network protocols (e.g., IPX/SPX). Each SNMP device (e.g., router, gateway, server) has an agent that collects information about itself and the messages it processes, and stores that information in a database called the management information base (MIB). The network manager’s management station that runs the network management software has access to these MIBs. Using this software, the network manager can send control messages to individual devices or groups of devices asking them to report the information stored in their MIB. As the name suggests, SNMP is a simple protocol with a limited number of functions. Characteristics of good monitoring templates:
