De plus, le collecteur peut ex\u00e9cuter des scripts personnalis\u00e9s lorsque des seuils sont d\u00e9pass\u00e9s.

Une pr\u00e9-agr\u00e9gation se fait au sein du collecteur.\n<li class=\"l\"> Le collecteur prend en charge par d\u00e9faut un ensemble de champs Netflow de base, mais il est possible d\u2019ajouter presque n\u2019importe quel champ.\n<li class=\"l\"> La performance du collecteur, en fonction de la nature du trafic et des rapports, peut atteindre plusieurs centaines de milliers \u00ab flows per second \u00bb sur un CPU. Le mod\u00e8le de r\u00e9partition de la charge est bas\u00e9 sur l'appareil (routeur) par flux.\n<li class=\"l\"> Le collecteur utilise des moyennes glissantes pour calculer l\u2019exc\u00e8s de vitesse du trafic.\n<li class=\"l\"> Le collecteur peut \u00eatre utilis\u00e9 pour rechercher des h\u00f4tes infect\u00e9s (envoyant du spam, \u00e9tant \u00e0 l'origine de flood HTTP(S), scanneurs SSH), pour identifier des pics soudains lors d'attaques DoS\/DDoS.\n<li class=\"l\"> Les rapports r\u00e9seau peuvent \u00eatre visualis\u00e9s \u00e0 l'aide de diff\u00e9rentes utilitaires : gnuplot, scripts en Python + Matplotlib, en utilisant Grafana.\n<li class=\"l\"> Contrairement \u00e0 de nombreux collecteurs modernes, le projet n'utilise pas Apache Kafka, Elasticsearch, etc., les principaux calculs se font \u00e0 l'int\u00e9rieur du collecteur lui-m\u00eame.  <\/ul>\n<p>Source : <a content=\"nofollow\" rel=\"nofollow\"
