Presentation Transcript

  1. Network Monitoring at FermilabCMS Computing Meeting Andrey Bobyshev DCN/CCF Fermilab, March 2003

  2. Outline of the talk: • What do we monitor for CMS • Switch port statistics • External connectivity (pinger) • topN - top 20 hosts, scanners, pairs • Local groups, external sites traffic (netflow based) • CMS traffic • Summary

  3. CERN UCSD U.WISC S-CMS-FCC1 Connectivity map UFL Off-site CALTECH Fermilab Core Network S-S-HUB-FCC CMS Computing Farms 2Gbps

  4. Start Point for Network Statistics HTTP://www-dcg.fnal.gov Requires userid/password to access from Offsite

  5. Monitoring of local traffic HTTP://www-dcg.fnal.gov/ Statisics -> Node Locator or MRTG data Uplinks to the core are ports 1/1 and 1/2

  6. MRTG Data for s-cms-fcc1- port 1/1

  7. External Connectivity HTTP://PINGER.FNAL.GOV We are hep.net

  8. Fermilab -Caltech graphs

  9. TopN - top 20 outbound/inbound hosts

  10. Traffic of Local Groups and Remote Sites

  11. Breakdown of CMS traffic to/from Remote sites

  12. IEPM-BW http://dmzmon0.deemz.net/~wanbanmon/html/slac_wan_bw_tests.html http://www-iepm.slac.stanford.edu/bw/

  13. Summary: • Start point http://www-dcg.fnal.gov • Node Locator & MRTG - local traffic & troubleshooting • topN - top 20 inbound/outbound talkers • pinger - RTT & packet loss • Local groups and remote sites traffic (netflow based) • Breakdown of CMS traffic • IEPM-BW - active performance measurements
