Additionally, the collector can run custom scripts when thresholds are exceeded. The project core is written in C, and the code is distributed under the ISC license.    <\/p>\n<p>Collector Features:  <\/p>\n<ul>\n<li class=\"l\"> Aggregated data by the necessary Netflow fields is exported to PostgreSQL. Preliminary aggregation occurs within the collector.\n<li class=\"l\"> Only a basic set of Netflow fields is supported out of the box, but almost any field can be added.\n<li class=\"l\"> The performance of the collector, depending on the type of traffic and reports, can reach several hundred thousand \"flows per second\" on a single CPU. The load distribution model is per device (router) per flow.\n<li class=\"l\"> The collector uses moving averages to calculate traffic speed exceedances.\n<li class=\"l\"> The collector can be used to identify infected hosts (sending email spam, HTTP(S) floods, SSH scanners) and detect sharp spikes during DoS\/DDoS attacks.\n<li class=\"l\"> Network reports can be visualized using various utilities: gnuplot, Python scripts + Matplotlib, or Grafana.\n<li class=\"l\"> Unlike many modern collectors, this project does not use Apache Kafka, Elastic, etc.; most calculations are performed within the collector itself.  <\/ul>\n<p>Source: <a content=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=58958\">opennet.ru<\/a>
