Monitoring backbone networks

This presentation at the E-infrastructure Autumn Workshop in Chisinau discusses the importance of monitoring backbone networks and provides insights into the tools, facts, and best practices for implementing monitoring systems. Topics covered include industry standards for data collection, SNMP and NetFlow-based tools, and case studies of monitoring solutions in the Romanian Education Network.

Presentation Transcript

  1. Monitoring backbone networks Manuel Șubredu, Valeriu Vraciu – RoEduNet Chișinău, September 9, 2014

  2. Agenda • Why ? • What ? • How ? • Tools ? • Facts ! E-infrastructure Autumn Workshop, Chisinau, September 8-11, 2014

  3. Why ? A picture is worth a thousand words ! – Frederick R. Barnard, 20th century E-infrastructure Autumn Workshop, Chisinau, September 8-11, 2014

  4. 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

  5. How Always use Industry standards for collecting data like: • SNMP • NetFlow v5/v9 and IPFIX E-infrastructure Autumn Workshop, Chisinau, September 8-11, 2014

  6. 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

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

  8. NMIS (main page) E-infrastructure Autumn Workshop, Chisinau, September 8-11, 2014

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

  10. Cacti (custom temperature graph) E-infrastructure Autumn Workshop, Chisinau, September 8-11, 2014

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

  12. RoEduNetWeathermap E-infrastructure Autumn Workshop, Chisinau, September 8-11, 2014

  13. 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).

  14. Nfsen (main page) E-infrastructure Autumn Workshop, Chisinau, September 8-11, 2014

  15. Facts forRomanian Education Network ! • 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 E-infrastructure Autumn Workshop, Chisinau, September 8-11, 2014

  16. VTR E-infrastructure Autumn Workshop, Chisinau, September 8-11, 2014

  17. 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.
