2019-07-01Cosmetic change when printing warningsProvoost1-1/+3
Warnings can be printed in the following cases: - When not enough packets are taken into account for measuring packet latency accuracy. - When there us a potential network throughput issue, meaning the generator is generating more packets than the the NIC can handle - When the generator cannot generate the requested load If there are no warnings for a certain measurement, nothing gets printed, suppressing an empty line Change-Id: Iee07c12142e28dcc0ac406bfed7626731ab08f98 Signed-off-by: Luc Provoost <luc.provoost@intel.com>
2019-06-30Multiple changes for June releaseLuc Provoost25-713/+861
- 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.

2019-06-14Increase window size for latency accuracyXavier Simonart3-15/+19
Accuracy of latency is obtained by writing TX accuracy for packet N in a later packet i.e. packet N + WINDOW. If this window is too small, packet N + WINDOW (conveying accuracy for packet N) might arrive before packet N, resulting in no accuracy for packet N. This change increases this window from 64 to 8K packets. This change should result in a higher number of packets used for latency measurements when packets are reordered. This change might have a performance impact as it uses more memory.

2019-06-14Support multiple tasks in "dp core stats" commandXavier Simonart2-10/+31
The "dp core stats" command supported, as other commands, multiple cores but not multiple tasks. It now supports both (e.g. dp core stats 1-2 0-1). This is necessary so that users can collect all statistics from PROX in one command line. It will return similar information on the screen or through the socket: - if the syntax is wrong (e.g. missing task, too many cores or tasks, ...) => an error message is printed on the screen, and the single error line "error: invalid syntax" is returned through the socket - if the syntax is correct => one line is printed or returned for each core/task pair => if the core/task pair is invalid, the line reports an error => otherwise, the line provides dataplane statistics for the core/task pair, with the core_id and task_id added, either at the end of the line returned through the socket, or at the beginning of the line printed on the screen. This means a change in behaviour when using the socket: before, when an error happened (e.g. bad task), then nothing was returned which made it difficult for the script to catch the syntax error. Similar behaviour could/should be implemented for other commands. However, care must be taken as some scripts like NSB might count the number of lines within the output, or the number of items within the line. This should not be an issue for dp core stats as NSB does not use it, and other PROX scripts do not count the number of items and will be adjusted to count the number of lines.

2019-06-14Add "total TX fail" count to "dp core stats" command outputPatrice Buriez3-4/+11
Warning: This change breaks backward-compatibility of PROX socket scripting API, because the "total TX fail" count is reported before the "last TSC" field. As a result, PROX scripts that make use of the "dp core stats" command, such as the core_stats() method in helper-scripts/openstackrapid/prox_ctrl.py, MUST be reworked to correctly parse the returned set of fields.

2019-03-08Fix PROX generator latencyXavier Simonart2-4/+23
When PROX fails to transmit packets (e.g. because switch or NIC is overloaded) some cleanup needs to be done related to packet id and latency. In addition, in some casesi, the clock estimate is slighly over-estimated which might result, in rare cases, in negative (hence very high) latencies, due to the extrapolation of timestamps. This has been workarounded bydecreasing the extrapolation, tolerating up to 1% clock estimate error Change-Id: I1ba17dfe0d5e2f9f9167f4f087ed0d96da1293c2 Signed-off-by: Xavier Simonart <xavier.simonart@intel.com>

2019-03-06PROX generator: performance optimization (2/4)Xavier Simonart8-162/+101
Improve PROX generator performance by pre-calculating bytes_to_tsc. This improvement is only implemented for non-pcap generator, where only few different packet sizes are usually generated. This change might have a negative performance impact in some cases, if many different packet sizes are generated, resulting in higher memory usage. This is the case for instance if random is applied to packet size. In addition, simplified the rx path, receiving now only MAX_PKT_BURST packets per handle loop. Before we were trying to empty the NIC looping on RX packets, ending up with many rx packets per handle loop. This was used to determine an lower bound for the time the packet was received. We now set the lower bound when less than MAX_PKT_BURST has been received. Change-Id: I1ce813d7e4ac1577ea412c590add5d6f94b36ec7 Signed-off-by: Xavier Simonart <xavier.simonart@intel.com>

2019-02-20Use link speed from device capability instead of negotiated speedaXavier Simonart4-13/+94
JIRA: SAMPLEVNF-151 link speed is used in gen and lat latency extrapolations. Using a link_speed value lower than the actual link speed might result in errors (e.g. negative latencies). Negotiated link speed might be reported slowly (as reported through irq) Hence it is better to use the device capability link speed. In addition, this remove the check for link speed changes in fastpath. Change-Id: I0f475fe5e139b046012de6cd0b710e4390735078 Signed-off-by: Xavier Simonart <xavier.simonart@intel.com>

Those timers values were hardcoded. They can now be configured through the configuration file (within the core section), using resp. "arp update time" and "arp timeout" keywords. Unit is milli seconds. The default becomes respectively 1 second and 2 weeks. Change-Id: I35e46e97df32ca44c2cdfae85a20ee015de5d6e1 Signed-off-by: Xavier Simonart <xavier.simonart@intel.com>
