This patch removes dependencies on testrepository as stackviz is using stestr instead. Closes-Bug: 1735667 Change-Id: I1e1de567fae7a2f7985f51e35d71201be2ab787f

Python Data-Processing Module (stackviz-export)
|
|
===============================================
|
|
|
|
The main purpose of :code:`stackviz-export` is to parse subunit and dstat logs
|
|
in order to generate configuration files for the AngularJS front-end.
|
|
|
|
Installation
|
|
============
|
|
Once Stackviz has been cloned into a suitable directory, setting up the module
|
|
is as simple as::
|
|
|
|
sudo pip install .
|
|
|
|
Usage
|
|
=====
|
|
:code:`stackviz-export [options] <DEST>`
|
|
|
|
Where DEST is the output directory of the module. If DEST does not exist, a new
|
|
directory will be created. One of the following input options must be chosen:
|
|
|
|
**-f, --stream-file FILE**
|
|
Specifies a subunit stream file to be used with the exporter. This
|
|
argument can be used multiple times to specify additional subunit files.
|
|
|
|
**-i, --stdin**
|
|
Instructs stackviz-export to read a subunit stream from stdin.
|
|
|
|
**-r, --repository REPOSITORY**
|
|
Specifies a :code:`.stestr` to read subunit streams from. This
|
|
argument can be used multiple times to specify additional repositories.
|
|
|
|
Stackviz also visualizes machine utilization statistics using dstat. To attach
|
|
a dstat.csv log to the subunit output, specify the following option:
|
|
|
|
**--dstat FILE**
|
|
Specifies a csv-formatted dstat log file that corresponds with the
|
|
provided subunit stream file.
|
|
|
|
Additional options:
|
|
|
|
**-h --help**
|
|
Print help message.
|
|
|
|
**-z --gzip**
|
|
Enables gzip compression for data files.
|
|
|
|
Output
|
|
======
|
|
:code:`stackviz-export` outputs the following files to the destination directory.
|
|
Note that <source> in the details, raw, and tree logs refer to what stream
|
|
source the
|
|
|
|
**config.json**
|
|
Contains all the basic information about a dataset that the front-end needs.
|
|
There will be one `tempest` entry for every dataset that was generated in
|
|
:code:`stackviz-export`. Each `tempest` entry has general information about
|
|
each run, as well as the locations of the details, raw, and tree JSON files.
|
|
|
|
**dstat_log.csv**
|
|
This file will only be present if a dstat log was used in the corresponding
|
|
:code:`stackviz-export` run. Has a wide variety of system statistics
|
|
including CPU, memory, and disk utilization. This information is displayed
|
|
on the timeline graph.
|
|
|
|
**tempest_<source>_<id>_details.json**
|
|
The details log contains timestamp and status information for tests in
|
|
addition to all of the logs associated with the test (e.g. tracebacks).
|
|
These artifacts are displayed in the test details page.
|
|
|
|
**tempest_<source>_<id>_raw.json**
|
|
Contains nearly all information available about tests:
|
|
- :code:`status`: pass, fail, or skipped
|
|
- :code:`name`: full name of test
|
|
- :code:`tags`: which worker the test was run on
|
|
- :code:`details`: empty, this info is available in the details JSON
|
|
- :code:`duration`: how long the test took, in seconds
|
|
- :code:`timestamps`: timestamps at test begin and test end
|
|
|
|
This file is used in the timeline and test details page.
|
|
|
|
**tempest_<source>_<id>_tree.json**
|
|
Stores test names in a hierarchy for display on the deprecated
|
|
sunburst diagram. Not currently used by any page in Stackviz.
