* Add some input data validation when parsing the output histogram from cyclictestwork/v2.0David Sommerseth2014-01-221-0/+8
| | | | | | | Backport of commit e0ca74e9c9f7f83a9db08d062b5ca8bdf05ff748 from v1.3x Signed-off-by: Clark Williams <clark.williams@gmail.com> Signed-off-by: David Sommerseth <davids@redhat.com>
* Fix --onlyload and reportdir being set to NoneDavid Sommerseth2013-11-081-1/+1

* Added new measurement module, sysstatDavid Sommerseth2013-06-174-3/+176
| | | | | | | | | | | | This module runs in parallel with cyclictest and will every minute use sysstat/sadc to collect all available system statistics. These statistics is both added as a single file to the tarball and embedded into the summary.xml. Also changed the polling time which checks if measurement and load modules are alive from every second to every minute. Signed-off-by: David Sommerseth <davids@redhat.com>
* cyclictest: Added trace-cmd extract when breaktrace aborts exectionDavid Sommerseth2013-05-021-0/+10
| | | | | | | | This adds a dependency of the trace-cmd package as well, but it will improve the ability to better understand what happened when this the threshold broke. Signed-off-by: David Sommerseth <davids@redhat.com>
* cyclictest: Don't bother reporting 'variance'David Sommerseth2013-04-152-15/+2
| | | | | | | | | | | | | | | | | | | | | The data used to do the mathematical reporting is based on histogram data, where the calculated variance will be rather pointless to gather. Imagine you have 3 samples in the historgram in the 2000µs slot, even if you have quite a lot of data with the average measurements around 50µs, the calculated "variance" for that time slot will be (1950^2)*3. Even though the final variance calculation will divide on number of samples gathered, it will take an enormous amount of samples within a the lower time slots to make this value interesting. So rather, don't report or save the calculated variance. However, the standard deviation is based on the variance, that value is far more sane due to the needed square root function on the final variance value. So it gives a far more sane and interesting value. The applied math in the cyclictest module should be fine itself, it's just the variance value that isn't much interesting on this kind of data source.

* Added timestamps tracking when each module starts and stopsDavid Sommerseth2013-03-142-0/+33
| | | | | | | | Currently ignoring load modules in general, as the <loads/> tags isn't easily extended. Not convinced it makes any sense to track these time stamps on load modules anyway. Signed-off-by: David Sommerseth <davids@redhat.com>
* Migrated from libxslt to lxmlDavid Sommerseth2013-03-132-22/+60
| | | | | | | To avoid depending on libxslt-python, use the more standard Python lxml module for XSLT processing. Signed-off-by: David Sommerseth <davids@redhat.com>
* hackbench: Adjusted the clean-up after running the load runs have completedDavid Sommerseth2013-01-311-3/+6
| | | | | | Ensure that hackbench really is stopped before continuing further. Signed-off-by: David Sommerseth <davids@redhat.com>
* hackbench: Wait for hackbench to completeDavid Sommerseth2013-01-311-0/+2
| | | | | | | | | | | As the rtevalModulePrototype::run() method will call Hackbench::_WorkloadTask() every second without ensuring hackbench is running first - wait for hackbench to complete before returning from _WorkloadTask(). This approach was chosen here as Hackbench is normally a shortliving process anyway. Signed-off-by: David Sommerseth <davids@redhat.com>
* cyclictest: Clean-up more object internal variablesDavid Sommerseth2013-01-291-68/+68
| | | | | | | Also resolvs some potential naming conflicts with the 'id' and 'type' variables. Signed-off-by: David Sommerseth <davids@redhat.com>

* cyclictest: Only log and show statistic data when samples are collectedDavid Sommerseth2013-01-182-63/+66
| | | | | | | | Avoids saving misinformation in the report, by just reporting the latency statistics when samples have been collected. In addition also avoid displaying these empty fields in the summary report. Signed-off-by: David Sommerseth <davids@redhat.com>

* cyclictest: Report if breaktrace was triggeredDavid Sommerseth2013-01-182-4/+47
| | | | | | | Adds a note in the summary report if breaktrace was triggered with some info related to that. Signed-off-by: David Sommerseth <davids@redhat.com>
* cyclictest: Use a tempfile buffer for cyclictest's stdout dataDavid Sommerseth2013-01-181-5/+13
| | | | | | | | | | | | | | Using subprocess.PIPE doesn't allow cyclictest to completely exit before the pipe is emptied. When using cyclictest with --breaktrace, rteval will then not see that cyclictest isn't measuring and will wait until the complete measurement duration has completed instead of doing an earlier exit. By using tempfile.SpooledTemporaryFile(), subprocess have a valid file descriptor it can write the stdout data too. This makes also cyclictest exit instantly when it needs to. Signed-off-by: David Sommerseth <davids@redhat.com>
* cyclictest: Removed --cyclictest-distance optionDavid Sommerseth2013-01-171-5/+0
| | | | | | | As rteval depends on cyclictest running in histogram mode, the distance argument doesn't make sense as cyclictest enforces it to 0. Signed-off-by: David Sommerseth <davids@redhat.com>
* cyclictest: Added --cyclictest-breaktrace featureDavid Sommerseth2013-01-171-3/+40
| | | | | | | | This enables the --breaktrace feature in the cyclictest tool, but rteval will also collect the trace data and put it in the resulting tarball. Signed-off-by: David Sommerseth <davids@redhat.com>

* Add a 30 seconds sleep before unleashing the measurement threadsDavid Sommerseth2013-01-171-0/+2
| | | | | | | | | | | This is to help the system to settle down before kicking off the realtime measurement workload. Otherwise some abnormal latency spikes might be logged, which would be false alarms. Considering that the a measurement run should run for several hours, this time-shifting for 30 seconds shouldn't really change the overall results. Signed-off-by: David Sommerseth <davids@redhat.com>

* Reworked the run logic for modules - allow them to flag they won't runDavid Sommerseth2013-01-153-33/+50
| | | | | | | | | | If a module sets the self._donotrun flag to True, the module logic will take care of not running this module at all. This also sorts out some issues when hackbench is not run, where some of the log file descriptors are not found when cleaning up in the end. Signed-off-by: David Sommerseth <davids@redhat.com>

* Fix up type casting in the core module codeDavid Sommerseth2013-01-141-4/+4
| | | | | | | If rteval is used as a library, it would easily throw an exception due to the wrong data type. This patch makes it a bit more flexible. Signed-off-by: David Sommerseth <davids@redhat.com>
* Put the rteval version into a separate importable fileDavid Sommerseth2013-01-102-2/+27
| | | | | | | | | | | | This is to avoid having massive build requirements just to retrieve the rteval version. The version string is also still available via the rteval module as well, to avoid other external implementations to fail with this change. But that variable is basically just a "re-export" of the value found in rteval/version.py Signed-off-by: David Sommerseth <davids@redhat.com>

* Corrects RuntimeError behavior using a new rtevalRuntimeError for modulesRaphaël Beamonte2013-01-042-9/+35
| | | | | | | | | | | Previously, when a module was raising a RuntimeError, parent threads weren't using it to stop the execution of the program. As RuntimeError are frequently fatal for what we want to set for the execution of rteval, this patches proposes to use a new rtevalRuntimeError which will set a flag on a module when raised to allow its parent to raise a RuntimeError to the main thread.

* Added infrastructure to add command line arguments from modulesDavid Sommerseth2012-12-183-10/+70
| | | | | | | | | | | | | | All rteval modules must now provide a ModuleParameters() function which returns a dictionary containing the option setup it expects. Each module will get a separate option group, and all its options will be prefixed with the module name. These option variables will be stored as well, prefixed with the module name. So if the a module 'dummy' configures an option 'value1', it will be stored as 'dummy_value1' in the option container. To set this option, you will need to use --dummy-value1 from the command line.
