Monitoring backbone networks

Why ?

A picture is worth a thousand words ! – Frederick R. Barnard, 20th century

E-infrastructure Autumn Workshop, Chisinau, September 8-11, 2014


What to monitor

What to monitor ?

  • Backbone and critical equipment – routers, switches, firewalls, load-balancers, etc

  • Servers and services

  • Values of traffic

  • Error rates

  • Transport network equipment, if available

E-infrastructure Autumn Workshop, Chisinau, September 8-11, 2014


Monitoring backbone networks

How

Always use Industry standards for collecting data like:

  • SNMP

  • NetFlow v5/v9 and IPFIX

E-infrastructure Autumn Workshop, Chisinau, September 8-11, 2014


Tools

Tools

  • OSS Software largely available

    • SNMP based:

      • NMIS

      • Cacti

      • Weathermap

    • NetFlow based:

      • NFSEN/NFDUMP

  • Custom software

    • Maps using free API from Google Maps (CEENGINE VTR)

    • Maps using different technologies: JS, ActionScript, PHP, SVG, etc(RoEduNetWeatherMap)

  • Proprietary software

    • For optical network

E-infrastructure Autumn Workshop, Chisinau, September 8-11, 2014

Facts forRomanian Education Network !

  • NMIS:

    • home: https://opmantek.com/network-management-system-nmis/

    • 90 routers and 20 switches monitored

    • Uses SNMP for collection of data

    • Xen based VPS - 1 x Xeon 2.4Ghz, 1G of memory, 64G of disk

    • OpenSuSE (64 bits)

    • Average load of the server – 2-3

    • 3G of disk space for data since 2009 (5 years)

    • Requires some knowledge of Linux system and services for setup

Facts forRomanian Education Network !

  • Cacti

    • home: http://www.cacti.net/

    • Uses SNMP for collecting data

    • Can easily monitor any OID that returns an integer (think about temperature, number of routes, etc)

    • Easy deployment and small requirements (web server with PHP)

    • Easy administration using a web interface

    • Authenticated access, configurable per user views

Facts forRomanian Education Network !

  • Weathermap

    • home: http://www.network-weathermap.com/

    • Uses RRDs from NMIS

    • Can be build using only OSS technologies like SVG and JavaScript

    • Is very flexible and can accommodate all kind of data visualisation

    • Major downside – requires some programming skills

Facts forRomanian Education Network !

  • Nfsen/nfdump

    • home: http://nfsen.sourceforge.net/

    • Uses NetFlow (v5 or v9)

    • Can have profiles of subset of data (think about graphs by service type or by IP addresses)

    • Supports plugins (Perl knowledge is required)

    • Supports alerts based on threshold or deviation from the mean

    • Major downside – lots of hardware needed on big networks: 1 server for data processing (8 x Xeon E7000 2.8Ghz with 64G of memory) and 22T of storage for 6 month of NetFlow’s exported by 13 core routers (8-12Gbps average traffic).

  • CEENGINE Visual Traceroute

    • home: https://noc.ceengine.eu/vtr/

    • Based on Google Maps

    • Heavy use of JS and custom web services

    • Backend and data collector written in Perl

Facts forRomanian Education Network !

  • Custom maps

    • home: N.A.

    • Frontend based on JS and HTML5

    • Backend uses multiple OSS services and technologies:

      • Lots of data input points: email, http, logs, other databases.

      • PostgreSQL as database server

      • Perl for data processing

      • REST API

    • Low hardware requirements: 1 Xen based VPS with 1 Processor and 4G or memory.
