eHealth @ ISISeHealth @ ISIS Traffic Accountant (TA)

1999: LAN probe based – but probe data was incorrect Late 1999: Migration from probe to Cisco Netflow based TA eHealth Netflow Import for accounting internet customer traffic Big amount of data: over 100,000 nodes in database in a few days Server and database encountered growth problems:

Polling can’t complete before next poll begins Rollups not completing at night – takes up to 12 hours !!! “Fork failed for netflow import”, “NH Server stopped unexpectedly” and restarts often a day

Result: TA / Netflow import disabled since early 2000 Workaround: script and cron based TA, developed at ISIS Working together with Concord to solve the problem

Summer 2001: Participated in beta test cycle for Release 5.x Still the same problems - TA / Netflow import still disabled To be continued … never ending story ???


How it works together ...How it works together ... eHealth:

Historical and trend reporting Customer & SLA reporting (Traffic Accountant)

HP Open View NNM: Graphical network view and node status

Other element managers Lucent, Marconi, Siemens, ...

HP Open View Operations (OVO): Main management console Event manager for all systems and element

managers Agilent Advisor

Real time network analysis and 7 layer protocol decoding, LAN/WAN


ROIROI

SLA monitoring for: Customer circuits Server systems

Reporting for circuits / leased lines per customer request

Proactive bandwidth control (Health Reports)

eHealth reports gives the answer to the statement:

“I can’t work – there must be a problem with the network.”

“The fault is not the network.” “The fault is not the server.”


Future PlansFuture Plans

Upgrade to eHealth 5.0.2 Server- and process monitoring in firewall

protected internet segment Integration of Marconi SDH (MV38)

Non IP and non SNMP based !!! Proprietary protocol (Q3) ASCII-Import (Concord / Partner ?)

Integration of Lucent Anymedia DSL Testing Application Response VLAN monitoring and reporting
