From b12d21d5850ade955a54e6296e387871c4b7560f Mon Sep 17 00:00:00 2001 From: Ancuta Enache Date: Fri, 28 Feb 2020 10:24:21 +0200 Subject: Ixia Live Results This patch collects Ixia live results and copy the results file from generator machine to local server 1. Traffic Item Statistics are collected during traffic running 2. Results file is copied from traffic generator machine to local server 3. Fixed pylint errors and made b2b test running working 4. Replacing sleeping times with traffic state verifications JIRA: VSPERF-609 Signed-off-by: Ancuta Enache Change-Id: I351c3a5435a71acfd1b6bc85bc6c0731d2529cd8 --- tools/pkt_gen/ixnet/ixnet.py | 76 ++++++++++++++++++++++++++++++++------------ 1 file changed, 56 insertions(+), 20 deletions(-) (limited to 'tools') diff --git a/tools/pkt_gen/ixnet/ixnet.py b/tools/pkt_gen/ixnet/ixnet.py index 87fb2c65..93d9bb47 100755 --- a/tools/pkt_gen/ixnet/ixnet.py +++ b/tools/pkt_gen/ixnet/ixnet.py @@ -83,6 +83,7 @@ import logging import os import re import csv +import random from collections import OrderedDict from tools.pkt_gen import trafficgen @@ -129,7 +130,7 @@ def _build_set_cmds(values, prefix='dict set'): if isinstance(value, list): value = '{{{}}}'.format(' '.join(str(x) for x in value)) - yield ' '.join([prefix, 'set', key, value]).strip() + yield ' '.join([prefix, key, value]).strip() continue # tcl doesn't recognise the strings "True" or "False", only "1" @@ -176,10 +177,9 @@ class IxNet(trafficgen.ITrafficGenerator): :returns: Output of command, where applicable.
