Organising of the NetIIS System

This article discusses the importance of organizing the NetIIS system for efficient monitoring and successful network performance measurement. It covers best practices for organizing data hierarchy, monitoring communication links, and device monitoring. Graphs and visual representation of the network topology are also explored.

  1. Organising of the NetIIS System Information System Monitoring System

  2. Organising The Information System • Defining the data information system hierarchy • Solid data organisation is a precondition for simple and efficient use of the NetIIS system and successful network performance measurement • Good practice - Folders into a logical division: • Geographical regions, cities or parts of the network • Types of locations in the network (e.g. faculties, institutes, libraries etc.) • Services and technology that are used in some part of the network (LAN, WAN, dial-up, wireless etc.)

  3. Database hierarchy

  4. Good practice • Locations should be configured on lower levels of hierarchy • Device • Users • Special Folders (LAN, WAN, Servers) • Folders at the top of the hierarchy that would contain pages with data overview • Groups for Monitors • Graphs • Looking Glass Groups • Reports • Faster access to objects of interest • External links • Backbone • Most important devices, servers and services

  5. Links topology

  6. Organising The Monitoring System • Communication links monitoring - basic monitoring in computer network • In a case of communication link break down, the devices and part of the network on the other side of the link will remain unavailable to the NetIIS server, unless there is an alternative line

  7. Organising The Monitoring System • On the near end port: • Port Monitor • Traffic Monitor • Packet Monitor • BGP Monitor (optionally) • On the far end port/device: • Ping Monitor

  8. Organising The Monitoring System • For the status of the connection to the remote Location it is recommended to group all of these Monitors • This Group can be set below the Location that it is related to

  9. Device Monitoring • Various SNMP Monitors or Reports: • processor usage • memory usage • temperature of individual components queue size • frame-relay interface status • modem lines

  10. Device Monitoring • Server Monitoring • CPU usage • Memory usage • Disk Partitions • Processes • TCP Connections • Services • Logs • Network Printer • Number of pages printed • Toner status • Estimated number of pages to next service

  11. Graphs • Best overview of the network topology and status. • Created for most important network parts, such as external links, network backbone, regional centres etc. • Links between Locations - adding individual Locations into the Graph • More detailed illustration with Devices • add chosen Devices to Graph • locations will represent a rectangular area that adjoins belonging Devices • individual Ports can be added to Groups, but they will additional burden the picture, so they should be shown only when multi-links are being sorted amongst Devices
