Connect Communicate Collaborate E 2 ECU and Perf

Connect. Communicate. Collaborate E 2 ECU and Perf. SONAR Emma Apted, DANTE Operations LHC OPN Meeting, 20 April 2007

Monitoring Overview 1 Connect. Communicate. Collaborate • Each domain installs own/3 rd party software to capture status from network hardware • This status info sent to Perf. SONAR MP or MA • Measurement Point (MP) – Lightweight web service – Collecting network status info [UP / DOWN only] – XML file • Measurement Archive (MA) – Mainly historical archive for network status info – Also same functions as MP – SQL Database • MP / MA checks info and reformats into XML for collection by E 2 EMon

Perf. SONAR LHC Rollout Connect. Communicate. Collaborate

Monitoring Overview 2 Connect. Communicate. Collaborate • E 2 ECU Monitoring Instance queries Perf. SONAR MPs & MAs • E 2 EMon sends SNMP traps to Nagios plug-ins • Nagios sends status info to “dashboard” = Network Event Broker (NEB) • E 2 ECU watches NEB for faults • E 2 ECU opens ticket & contacts NRENs & ENOC • NREN can also send email / telephone E 2 ECU with fault • Right now only LHC OPN & IGTMD (IN 2 P 3 -Fermilab), later DEISA • DANTE has ongoing co-op with E 2 EMon developers

Future Plans / Questions Connect. Communicate. Collaborate • E 2 ECU is contacting NRENs / domains regarding : – Measurement Points availability – Consistency in naming of Monitored. Links / Demarcs • Further Implementation of MPs at Tier 1 centres • 24 x 7 E 2 ECU – US collaboration • Improvement of data accuracy from all domains • Should E 2 EMS be considered public info? • Matthias & Mark are working on software development • Presentation from E 2 ECU • Any questions? • See http: //wiki. perfsonar. net/jra 1 -wiki/
