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:

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


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
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 ???
