Presentation Transcript

  1. N-Wave Network Monitoring Dave Hartzell david.hartzell@noaa.gov

  2. Current Network

  3. Agenda • Active Monitoring • Passive Monitoring • Traffic Volume

  4. Active Monitoring • PerfSonar • Network distributed nodes • Geographically distributed w/core nodes • Perform periodic testing • Minimally intrusive • Reveals problems passive testing cannot • https://ndb.ctc.nwave.noaa.gov/

  5. Passive Monitoring • GRNOC SNAPP • Netflow

  6. Passive: SNMP • GRNOC SNAPP • Collection • Interface stats, CPU util, device temperature • Archiving • Presentation • https://snapp.bldc.nwave.noaa.gov/nwave

  7. Passive: Netflow • Passively sampled (1:1500 packets) • Done at the core-network edge, outgoing • Exported for archive (nfdump) • Currently analyzed with Excel • (go to Excel)

  8. Applications • Monitoring reveals: • Health of the N-Wave • Usage patterns of N-Wave • User benefits • Overall, there is a general “agreement” across the monitoring methods

  9. Total Traffic Transported • 60-70 TB/day peaks (March 2012): • 1.4 PB in January • 1.5 PB in February • 1.7 PB in March • 0.8 PB in April

  10. Traffic Volume

  11. CLASS- Apr 2012 (Circos)

  12. CLASS- Apr 2012

  13. R&D HPCS March 2012 (Circos)

  14. R&D HPCS March 2012 (Circos)

  15. R&D HPCS Apr 2012

  16. R&D HPCS Apr 2012 (Normalized)

  17. All N-Wave March 2012

  18. All N-Wave April 2012

  19. Monitoring Futures • New PerfSonarflows? • Multicast • IPv6 • Netflow • Practical and/or tactical analysis tool, such as InMon,ManageEngine, SolarWinds ($) • J-Flow (at the Juniper edge?)

  20. The End.
