2019-09-24Add support for HDRhistogramVratko Polak1-15/+17
+ Enable hdrh in trex server. + Append hdrh coded output after min/avg/max/. + Read (not show nor decode) hdrh value in PAL. + Also, remove old ndrpdrdisc code. Change-Id: I99d99f10386a621772b5419ca1f36080fa15aca7 Signed-off-by: Vratko Polak <vrpolak@cisco.com>
2019-09-24Reconf tests: Fix async measurementsVratko Polak2-6/+32
TRex does not zero the server counters. It copies the values to use as reference, and subtracts them when asked for results. But the reference is stored in the client (not the server). And CSIT uses different scripts to start and stop async traffic, which means different clients. This patch introduces a workaround. Async start will return xstats objects to use as reference, and async stop will use the objects to compute the correct results. The xstats objects are stored in TrafficGenerator instance. Sync measurement does not export the counters, to shorten logs. Other improvements: + Make stop_traffic_on_tg return measurement results directly. + Rename --async to --async_start as "async" is reserved in Python 3.7 + Minor pylint, docstring and typo fixes.

2019-08-23Introduce reconfig suites, for dot1q+ip4+vxlanVratko Polak1-13/+26
Ticket: CSIT-1551 + Config copied from other suites. + Layer keywords prepared for additional chains. + Renamed "create" argument to "vlan_per_chain". + TrafficGenerator result extraction improvements. + Also unified TG type and subtype checking. + Throughput estimated as PDR for zero PLR. + Actual Qemu start is skipped. + Parse xstats instead of stats in trex stop scipt. - Because stats are unconditionally cleared on each script connect. + Remember start values to get better ReceiveMeasurementResult at stop. + Expose loss count and time as appropriate test message. + Autogen support. + Multiple chain amounts and core densities. - Only 1 additional chain. + Proper TAGs. Documented. + Clarified min framesize tags are for TG-DUT. + Added a TODO concerning overhead values. + Added 118B tag. + Robot performance keywords improvements. + Added missing return value documentation. + Frame size as required test variable, not an explicit argument. + MLRsearch keyword to store result (not into test message). - TODO: De-duplicate: main keyword to measure, minor to set test message. - But implementation uses the fact default arguments are different. + Keywords for starting and stopping background traffic. - No checks whether start-stop pair is complete. + Multiple minor indentation and logging improvements. - Missing / TODOs: - Support also vlan_per_chain=True? - Support dot1q without vxlan? - Support also deletion? - How to package config steps so -reconf can be generated from -ndrpdr?

2019-05-10PLRsearch: Use stat trackers to shorten IntegratorVratko Polak1-3/+3
+ Extract several tracker classes and use them in Integrator. + Apply next_rate workarounds to focus more on critical region. + Rewrite stretch function, as the previous implementation was wrong. + Rework logging: ++ Use injected trace() function in Integrator. ++ Inject function that skips trace logging on default initialization. ++ Use the same multiprocessing-safe passing, but separate queue. + Set duration to 120m in Robot, but keep at 30m in Python. + Apply minor changes to make computations more reproducible: ++ Attempt to log everything needed by reproducibility in one line. ++ Log samples used, and make it settable as upper limit. ++ Use repr output in TRex scripts, to avoid rounding when copypasting. +- Numpy seems to be sharing PRNG between processes. +-- An edit to disable one thread is needed for full reproducibility. +-- Such an edit is prepared, but will not be merged anytime soon.

2019-02-26De-duplicate unidirection supportVratko Polak1-221/+46
- Latency is now reported in both directions. -- For unidirection that means additional -1/-1/-1. + Changed function argument wrapping to save vertical space. + Changed trex command synthesys to save vertical space. + Fixed handling of command line arguments to avoid superfluous spaces. + More care distinguishing (0, 1) from (port_0, port_1). - Not renaming the original port arguments.
