Ethr
ethr ist ein CLI-Netzwerkdiagnosetool und Performance-Analyzer, das darauf ausgelegt ist, Durchsatz, Latenz und Paketverlust über TCP-, UDP- und ICMP-Protokolle zu messen. Es fungiert als Multi-Threaded-Netzwerk-Durchsatztester und Diagnosewerkzeug zur Analyse der Verbindungsqualität zwischen Client- und Server-Endpunkten.
Das Projekt zeichnet sich durch spezialisierte Diagnosen wie die Überwachung von TCP-Retransmissionen und bidirektionale Pfadanalyse aus, um asymmetrische Performance-Unterschiede zu identifizieren. Es bietet die Möglichkeit, den Overhead verschlüsselter HTTPS-Verbindungen zu bewerten und spezifische IP-Versionen zu erzwingen, um protokollspezifische Engpässe zu isolieren.
Die breiteren Funktionen umfassen Netzwerk-Pfadverfolgung, Jitter- und Verzögerungsanalyse sowie Kapazitätstests zur Bestimmung maximaler Paket- und Verbindungsraten. Das Tool extrahiert zudem Rohdaten aus dem Betriebssystem und liefert Echtzeit-Schnittstellenstatistiken.
Messergebnisse und Systemereignisse werden in strukturierten Terminal-Tabellen dargestellt und können für Offline-Audits in JSON-Dateien exportiert werden.
Features
