Monitoring Appliance Status

This agenda covers monitoring parameters, deployment process for the LHCOPN, and features of perfSONAR MDM v3.0 and E2EMON. It also includes metrics collected and scheduling for delay, achievable bandwidth, traceroute, router interface statistics, and L2 circuit status.

  1. Monitoring Appliance Status Otto Kreiter, DANTE LHCOPN, Geneva, 17.06.2008

  2. Agenda • Monitoring parameters & monitoring scheduling (proposal) • Deployment process for the LHCOPN • perfSONAR MDM v3.0 & E2EMON features

  3. Monitoring parameters & Monitoring scheduling (proposal)

  4. Box-1 LHCOPN Box-2 Box-3 Typical T0-T1 measurement appliance installation reminder HADES Agent (delay) Pinger/Tracert-MP Cacti, RRD-MA (count) SQL MA(L2 stat) E2ESync Lookup service BWCTL tool – MP(TCP) perfSONARBuoy Auth. Service

  5. Metrics collected & scheduling • Delay - scheduled measurements • Owe-Way Delay (OWD), IP Packet Delay Variation (IPDV), One Way Packet Loss (OWPL) • Every 60s • Achievable Bandwidth - scheduled measurements • TCP throughput transfer (max. 950Mbit/s) • Every 6h • Achievable Bandwidth - on-demand measurements • TCP and UDP throughput transfer (max. 950MBit/s) • Traceroute - scheduled measurements • Hop list • Every 5 min

  6. Metrics collected & scheduling cont. • Router Interface statistics • Link capacity • Link utilisation • Interface input errors • Interface output drops • Every 5 min • L2 circuit status • domain and/or inter-domain circuit status (UP/DOWN) • Every 5 min

  7. Delay - scheduled measurements Enable • to identify routing issues (OWD) • to identify congestion (w/ or w/o packet loss) (OWD, IPDV, OWPL) • to identify high packet loss rate (OWPL) • to identify path instability (IPDV) • to keep a historical trace of the changes at a finer grained granularity (60s) • to validate the recovery of the service after failure • to verify consistency before and after maintenance

  8. Achievable Bandwidth -scheduled measurements Enable • to identify performance degradation • to compare data transfer rate against historical baseline from a well tuned host • to validate the recovery of the service after failure

  9. Achievable Bandwidth on-demand measurements Enable • to troubleshoot TCP throughput performances by running tests from a well tuned host and compare them against a historical information • to validate the recovery of the service after failure • to verify consistency of the performances before and after maintenance

  10. Traceroute - scheduled measurements Enable • to identify IP path stability over time • to identify routing issues • to validate the path recovery of the service after failure • to verify the path consistency before and after maintenance

  11. Router Interface statistics Enable • to identify traffic load for troubleshooting (congestion, heavy utilisation), long term trend and planning • to estimate the available bandwidth • to identify short term and long term congestion with losses (output drops) • to identify faulty links (input errors) • to verify traffic recovery after failure • to verify consistency before and after maintenance

  12. L2 circuit status Enable • to identify the status of a circuit segment in a given domain.

  13. Conclusion • Parameters and scheduling wel estalished but not nailed. • Scheduling can be customized as per customer needs. • Next step to demonstrate UI – next LHCOPN

  14. Deployment process for the LHCOPN

  15. perfSONAR MDM LHCOPN Site Deployment Site Deployment Steps: • Site survey • Hardware purchase • Shipment of the hardware to site • Hardware installation • Software installation • Service configuration

  16. perfSONAR MDMLHCOPN deployment steps • Deployment planned in phases • Each phase involves 4 sites • Each site will: • Be addressed individually • Have a dedicated Service Desk person • Successful deployment depends upon site collaboration

  17. perfSONAR MDM v3.0 & E2EMON features

  18. perfSONAR MDM 3.0 • Significant improvements to software installation • rpm and Debian packages • New 'Web Admin' interface • slick web based configuration interface for ease of configuration, administration and support of software. • Authentication and Directory services (Lookup) • validation of identities specified by eduGAIN • identity from various Identity Providers • The bundle contains 10 different web service software. http://wiki.perfsonar.net/jra1-wiki/index.php/PerfSONAR_v3.0

  19. E2EMON enhancement • SNMP trap for Nagios sensors / per project and per link to selected recipients (requested by PIC and IN2P3) • Feature available mid July.
