the tool flowgrind seems like it might be an interesting backend for flent to support: https://github.com/flowgrind/flowgrind
From its README:
> Unlike most cross-platform testing tools, flowgrind can output some transport layer information, which are usually internal to the TCP/IP stack. For example, on Linux and FreeBSD this includes among others the kernel's estimation of the end-to-end RTT, the size of the TCP congestion window (CWND) and slow start threshold (SSTHRESH).

These values Flent can already extract (using the 'ss' tool). Just enable --socket-stats :) Also from its README: > In contrast to similar tools like iperf or netperf it features a > distributed architecture, where throughput and other metrics are > measured between arbitrary flowgrind server processes. ...which makes me suspect it's not a very good fit for Flent. -- You are receiving this because you are subscribed to this thread.
