Agenda

• Active Monitoring• Passive Monitoring• Traffic Volume

For Official Use Only

Active Monitoring

• PerfSonar– Network distributed nodes • Geographically distributed w/core nodes• Perform periodic testing• Minimally intrusive• Reveals problems passive testing cannot

Passive Monitoring

• GRNOC SNAPP• Netflow

For Official Use Only

Passive: SNMP

• GRNOC SNAPP– Collection• Interface stats, CPU util, device temperature

– Archiving– Presentation

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)

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

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

Monitoring Futures

• New PerfSonar flows?– Multicast– IPv6

• Netflow– Practical and/or tactical analysis tool, such

as InMon, ManageEngine, SolarWinds ($)– J-Flow (at the Juniper edge?)
