5.3.0 

April, 2024


NETFLOW ANALYZER

5.2.0 

January, 2024 

NETFLOW ANALYZER

  • Until NetVizura 5.2, data were aggregated in 5-minute intervals. Now, we have reached a huge milestone – besides 5-minute it is possible to have data aggregated in 1-minute intervals. Henceforth you can monitor your traffic near real-time. Set up your desired data aggregation interval by following instructions on the page Data aggregation interval
  • Elasticsearch database becomes the main database. To learn more about its strengths and benefits, visit Elasticsearch
  • We have developed the Migration tool, an instrument for the swift transfer of data from PostgreSQL to Elasticsearch. Find out more on the following page NetVizura Data Migration
  • Charts and tables offer the functionalities you already use, however, they are now more modern, visually appealing and interactive

Data migration is only required if you are using previous versions of NetVizura (NetVizura 4.7.4 and older). Once you complete data migration, it is not possible to migrate data back to NetVizura 4.x version.


IMPORTANT NOTE: If you have both NetFlow Analyzer and EventLog Analyzer modules, please contact support@netvizura.com before clearing data from PostgreSQL.
