v0.14.028c9c3ae · ·
Flent v0.14.0. This release adds mixins for capturing qdisc stats and CPU usage, adds some convenience functions to the GUI and fixes a bunch of bugs, most notably making the GUI work on Windows. - Batch mode: Try to estimate the total runtime of a batch and print it before executing the batch itself. - GUI: Add support for pinning a metadata item open when flipping between tabs, and support adding columns to the open files view from the metadata view. Both functions are available from the context menu when right-clicking in the metadata view. - Add test mixins to a bunch of tests making it possible to simultaneously capture qdisc stats and/or CPU stats of one or more hosts while the test is run. This works by setting the test parameters qdisc_stats_hosts, qdisc_stats_interfaces and cpu_stats_hosts to comma-separated lists of hosts and interface names. The functionality relies on the tc_iterator and stats_iterator helper scripts. - Add a C implementation of the tc_iterator helper script that works on OpenWrt and also gives higher polling accuracy than the shell script. - Add a kill_timeout setting for runners in test definitions which will forcibly kill a subprocess after an interval (if it hasn't exited already). - Add the tcp_upload_1000 test for seriously overloading things. On most systems, increasing the ulimit is necessary to run this test. - Support globbing selectors in plot configuration when specifying datasets for a plot. - Record number of failed runners (non-0 exit status) as a metadata key. - GUI: Fix bugs in plot blitting on older matplotlibs, fix test running without a pre-set HOST, fix bugs in draw cache handling, and restore the GUI to a working state on Windows. - Various bugfixes.

v0.13.0eb231fa0 · ·
Flent v0.13.0. This release of Flent adds a couple of new features to the GUI, updates Iperf support and adds a bunch of bugfixes. - GUI: For line graphs (timeseries and CDF plots), highlight data series when the mouse is hovering over the lines themselves or their corresponding legend items. This makes it easier to pick out specific data series when browsing graphs. There's a toggle to turn off this feature, since it can perform badly on slow systems and/or causes flicker in some instances on OSX. - GUI: Experimental feature to run tests from the GUI. Fairly basic thus far, but it is possible to run a simple test from the GUI which will subsequently be loaded in the graph view. - File format: Bump file format to v3. The file format now uses UTC timestamps everywhere internally, which is an incompatible change; hence the version bump. Old data files will be loaded assuming local times and converted appropriately on load. File name date stamps are still done in local time for the box running the test. - Bring Iperf support up-to-date. The newest git version of Iperf (2) adds support for sub-second timestamps. Flent now detects this and can use and parse Iperf results when this support is detected. So far, no tests actually use Iperf, though. - Flent will now capture the module version of a running Cake shaper module as part of extended metadata. TCP buffer size limit sysctls are now also captured. - Some bug fixes related to matplotlib and Qt version compatibility and weirdness of the OSX file selector dialog.

v0.12.49da2975a · ·
Release v0.12.4. This is a small bugfix release. Changes since v0.12.3: - Packaging fixes for Debian. - Support for Python 2.6 has officially been dropped (it had already bitrotted, so now a nicer error message is shown straight away). - Bug in local_bind for ping commands fixed. - More graphs for tcp_* tests and fixed labels on HTTP test graphs. - Catch unhandled exception that caused crashed when using a null output formatter.
