It's an open source project ( NetTracer).It's independent from kernel version and configuration (Linux kernel 4.15 and higher).It's a high performance applicaton (written in C and C++).It can collect metrics about each traced connection.It can trace TCP events: connect, accept, and close.Binary that presents the data in a structured or semi-structured format.NetTracer is an open source tool for tracing TCP events and collecting network connection metrics on Linux. Extensive network traffic on particular nodes is a sign that you should consider scaling up the cluster. With network metrics added to your containerized hosts, DavisĀ® root cause analysis will leverage them and extend analysis to provide visibility into network-related issues. Extend network monitoring with network traffic metrics in containerized Linux hosts.
