    Netflow problem with big traffic

      NTA 2.1 with all hotfixes; SQL 2005 EE 64 bit (located on different server); daily traffic counted by NTA is about 160 GB. Server on which Orion is installed - 2xXeon 2.4Ghz, 4GB RAM. Only 1 Netflow source.

      NTA doesn't show all data when I select time range more than few hours.

      It shows all when:

      1) Time range is small - "Last 15 minutes", "Last hour" works fine.

      2) "Top XX transmitters", "Top XX receivers" - XX=5, but it's definitely not enough - we need to see at least top 25 downloaders.

       

      When I try to view data with conditions not satisfied with mentioned above, NTA shows "No protocol traffic information available for the selected time period.", "No application traffic information available for the selected time period.", "No endpoint traffic information available".
       

      We need to analyze traffic by previous day, sometimes by previous week but NTA can't help us at all.
