2020-09-16ramp generator traffic & prox.log copyLuc Provoost1-0/+47
A new parameter can be put in the *.test files so that the requested traffic is not generated at once, but slowly increasing up to the requested traffic. This is important for some SW switched that adapt and learn from the applied traffic. When suddenly applying a high traffic, the switch might not have enough time to learn and lose packets. Only after a period of time (up to 10 seconds?), the switch can cope with the traffic without packet loss. In order to get reproducible results in this case with low packet loss, please put the parameter ramp_step in the test section of the *.test file. The step is expressed in percentage of a 10Gb/s traffic. If the parameter is not present, the load will be immediately applied. When the runrapid.py script is now finished, it also copies the prox.log files from all the prox instances. In case of issues, please investigate this log file. When using background traffic, the tool will also print the average background traffic for each step in the DEBUG log. In this way, you can check that the background traffic is actually dealing with the same amount of traffic as the foreground. The tool is printing the packet reception rate of the background generators. A bug was also fixed regarding the latency percentile reporting. When using tests involving l2gen.cfg, the values of the percentile latency were wrong. Change-Id: Id3dd02ed5cab084414c717cf898b30e6980ddf31 Signed-off-by: Luc Provoost <luc.provoost@intel.com>
2020-08-06fix: IPV6 packet generation, packet loss reportingLuc Provoost1-1/+1
UDP and IP packet length and source UDP port and destination UDP port were wrongly set for IPv6 packets. In the *.test files, there is now an optional boolean field (ipv6) in the [TestParameters] section. When set to true, the generator will use the IPv6 packet layout to place the right values at the proper offset in the packet. If not present or set to false, the IPv4 layout will be used. Note also that packet size needs to be at least 84 bytes for IPV6 traffic since we need space for latency and other information in each packet. Packet loss ratio is now printed as a percentage of the total packets sent. Change-Id: I2136e87f3032348ae95b69052be7da8461c6303c Signed-off-by: Luc Provoost <luc.provoost@intel.com>
2020-08-03Improved IRQ measurements and pushing resultsLuc Provoost1-6/+81
The IRQ test has been reworked to increase the accuracy of the IRQ measurements. Results can now also be pushed to a Prometheus push gateway or to OPNFV's Xtesting. In order to do so, a new file format.yaml has been introduced. Please use this file now to specify the details of the PushGateway or the Xtesting server. Added new test: increment_till_fail.test Change-Id: I111aae3e099bc03e3d2ddd1014a0301bac356e0b Signed-off-by: Luc Provoost <luc.provoost@intel.com>
2020-07-05Adding vdev support and vfioLuc Provoost1-1/+12
Using vfio in stead of igb_uio. DPDK 2020.5 is NOT compiling the igb_uio driver by default any more. For the l3 mode, we are now using the new PROX vdev feature. This is achieved by adding the vdev parameter in the port section of the PROX config files. One of the advantages is that we can now ping a port managed by PROX: the requests will be forwarded by PROX to the LINUX stack, who will reply to the ping. A tap device is being created by PROX to support this feature. Installing old version of nasm since latest causes some issues. If not pushgateway is being used, it should be commented out in the config_file. vfio is now loaded by specifying the module in /etc/modules-load.d There is also an after_boot.sh script that will be run by check_prox_system_setup.sh, which can be used for further configuration of the instance after boot. There is now also a file created /opt/rapid/system_ready_for_rapid by the check_prox_system_setup.sh script. This file is created once all configuration is done. The runrapid.py script will wait till this file is created before executing any tests. Change-Id: Ic5c41af82642066af42134c3323297f5a06f6f72 Signed-off-by: Luc Provoost <luc.provoost@intel.com>
2020-05-29Fixing some more copyright datesLuc Provoost1-1/+1
New files created in 2020 have now the right date in the copyright notice. Change-Id: I8eb244beec3d793e819cce1f63c39671f18286a1 Signed-off-by: Luc Provoost <luc.provoost@intel.com>
2020-05-28IPV6 testing & minor changes and fixesLuc Provoost1-4/+16
IPV6 test has been added. The generator will now generate IPV6 packets using NDP to resolve MAC addresses. The hex IP addresses in the inline definition of the packets in the cfg files is now calculated by a lua function called in parameters.lua. The hard-coded path /home/centos has been replaced by ~. An error in the speed calculations has been fixed. See the RapidTest class for details. The actual number of generated flows is now reported. If the requested number of flows is not a power of 2, the lowest power of 2 that is larger than the requested number of flows will be used and reported.

2020-05-15Support for imix packet sizesLuc Provoost1-2/+3
All packet size in the *.test files have been replaces with imix sizes. imix is now a list of packet sizes. If you want to run with only a pakcet size of 64, you need to specify a list containing only 1 size: [64]. You can also specify multiple imix values by specifying a list of list of sizes. The keyworkds in the test files are now imix & imixs. Change-Id: Iea47c0266b022133b7bbfc9a6811e3199ae41521 Signed-off-by: Luc Provoost <luc.provoost@intel.com>
2020-05-15Code rewrite and Python3 supportLuc Provoost1-0/+290
The code has been rewritten in multiple classes and files for better readability and maintainability. You should now also use Python3 to run the scripts. Some of the variables in the config files have moved to other sections. The pushgateway parameter moved to the [varia] section of the rapid environment file.
