Description

Python wrapper to run multiple simultaneous netperf/iperf/ping instances and aggregate the results. This package contains the command-line tools. "pkg_add flent-gui" for the PyQt-based GUI. Several commands can be run in parallel and the test data points can be aligned with each other in time, interpolating differences between the actual measurement points. This makes it possible to graph (e.g.) ping times before, during and after a link is loaded. Aggregated data can be saved in a json format, output as csv values, emacs org mode tables, or graph plots. Each test can specify several plots, including time-series plots of the values against each other, as well as CDF plots of (e.g.) ping times. For basic use: install netperf on the server and run "netserver", then various tests can be run from a client machine with the flent package installed.
