2020-09-16ramp generator traffic & prox.log copyLuc Provoost1-0/+1
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>
2020-07-05Adding vdev support and vfioLuc Provoost1-1/+1
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>
2020-05-29Fix for container .env file and small updatesLuc Provoost1-1/+1
Since runrapid.py is now supporting more than 1 dataplane interface, we need to use a port index in the rapid.env file for the dataplane ports. In k8sdeployment.py, we only support 1 dataplane port, but we are writing dp_ip1 and dp_mac1 in the environment file. The copyright dates are also updated. Some references to VM have also been changed to instance. Change-Id: Ie1d036c13ef5d6f0aa1f35aa068a9760a1cfc2a9 Signed-off-by: Luc Provoost <luc.provoost@intel.com>
2020-05-28IPV6 testing & minor changes and fixesLuc Provoost1-2/+6
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/+2
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 Provoost1-17/+23
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.

2020-01-13Initial support for percentile latency measurementsLuc Provoost1-5/+7
We are now reporting a percentile number for the round-trip latency. The numbers are only correct for processors running at 2GHz. Will fix this next so it runs for any freqency. We only report 1-127 usec. If the latency goes higher, we are now reporting "VERY HIGH". Change-Id: If9fda63cea8616febcc0f24dc52590976cf39f3d Signed-off-by: Luc Provoost <luc.provoost@intel.com>
2019-11-26rapid november release combining changesLuc Provoost1-6/+5
-Renamed monitorswap.test into corestats.test. This is a more generic test case that can monitor the core statistics of all PROX instances -New portstats.test which can monitor the port statistics of all PROX instances -Removed the tasks parameter in the [DEFAULT] section of the *.test files. Runrapid.py is now scaning the PROX configuration files to automatically detect the PROX tasks that are being used. -There is now an option to add the PushGateway parameter in the [Default] section of some *.test files. This will push the measurements to the Gateway, so they can be used by tools like Grafana. The logging of the data in a csv file has also been improved. Results can now be found on the screen, in the RUN*.log files, in the *.csv files and are being pushed to the PushGateway. -In the *.test files, replaced the swapcores, irqcores and impaircores by the cores parameter since they are not treated differently by the code. For a generator, we are still using the gencores and latcores parameters since we need to treat them differently in runrapid.py -devbind.sh is removed from the repository since this file is now created by runrapid.py -renamed the rapidVMs.vms file into rapid.vms -image is now built without ssh access for root. Only using centos user. runrapid.py is now using centos user for ssh sessions. PROX tools are strted using sudo -using new DPDK, mb_lib and PROX versions as defined in deploycentostools.sh -installing missing yum-utils package in image -added flowsize parameter to the impairtest -added list of flowsizes to the fixed_rate testing (l3framerate.test) -the irqtest can now loop through multiple Test Machines in stead of only checking the irq of one. Note that we should have the same cores parameter for all Test machines -changes in prox_ctrl.py to support setting the speed of a generator on a combination of mulitple cores and tasks. Also added the multi_port_stats function to support the new portstats.test -Updated version to 19.11.21 -Fixed some power of 2 in the flow table Change-Id: Ia14543bf3195a2b1bd4184b455da6940f1777fc9 Signed-off-by: Luc Provoost <luc.provoost@intel.com>

2019-06-30Multiple changes for June releaseLuc Provoost1-17/+14
- Change inittest in warmuptest. This has now a warmuptime, warmupspeed, packet size and flow size. - Change in centos.json. This will now also copy deploycentostools.sh during image building so that it can be used to re-compile prox in the VM by typing "./deploycentostools.sh compile" - runrapid.py parameters needing a file name, need to be complete file names: no extensions will be added any more by the scripts. - Changes in createrapid.py to handel the openstack CLI output in a simpler way. - The management interface of the VMs can now also be an SRIOV interface. We have now an extra optional parameter in the VM sections of the rapiVMs.vms file: SRIOV_mgmt_port - Changed the name of some sections and keys in the environment file since runrapid.py will not always communicate to OpenStack VMs. This could be containers or any other (virtual) machine. - The previous MachineMap.cfg has been renamed to machine.map - A new test has been added: monitorswap is just showing the statistics of a swap (virtual) machine, without generating any packets. This is useful in situations where an external tester is used. - Latency and core statistics can now be measured even if there are multiple PROX cores and tasks running. A new parameter has been added in the test files with following default value: tasks=[0]. During the collection of statistics, all tasks in this list will be queried. It is ok to have a non-existing task in such a query since it will be ignored. - A --screenlog parameter was added for runrapid.py allowing for more detailed output on the screen during debugging. No need to check the log file. - Previous tests to run multiple packet size with a given flow size and to run multiple flow size, with a given packet size are now combined by specifiying 2 lists: packetsizes & flows - The screen output of this test has also been reworked with more meaningful column names and the test result is now in the field "core received". This allows also for faster termination of the test: When the all packets sent by Gen NIC are received by the cores within the thresholds for packet loss and latency, the test is now stopped, even we were requesting more packets to be sent.
