Output Processing API Example
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
To demonstrate how we can use the output API if we have an existing WA output
called ``wa_output`` in the current working directory we can initialize a
``RunOutput`` as follows:
.. code-block:: python
In [1]: from wa import RunOutput
...:
...: output_directory = 'wa_output'
...: run_output = RunOutput(output_directory)
From here we can retrieve various information about the run. For example if we
want to see what the overall status of the run was, along with the runtime
parameters and the metrics recorded from the first job was we can do the following:
.. code-block:: python
In [2]: run_output.status
Out[2]: OK(7)
# List all of the jobs for the run
In [3]: run_output.jobs
Out[3]:
[<wa.framework.output.JobOutput at 0x7f70358a1f10>,
<wa.framework.output.JobOutput at 0x7f70358a1150>,
<wa.framework.output.JobOutput at 0x7f7035862810>,
<wa.framework.output.JobOutput at 0x7f7035875090>]
# Examine the first job that was ran
In [4]: job_1 = run_output.jobs[0]
In [5]: job_1.label
Out[5]: u'dhrystone'
# Print out all the runtime parameters and their values for this job
In [6]: for k, v in job_1.spec.runtime_parameters.iteritems():
...: print (k, v)
(u'airplane_mode': False)
(u'brightness': 100)
(u'governor': 'userspace')
(u'big_frequency': 1700000)
(u'little_frequency': 1400000)
# Print out all the metrics avalible for this job
In [7]: job_1.metrics
Out[7]:
[<thread 0 score: 14423105 (+)>,
<thread 0 DMIPS: 8209 (+)>,
<thread 1 score: 14423105 (+)>,
<thread 1 DMIPS: 8209 (+)>,
<thread 2 score: 14423105 (+)>,
<thread 2 DMIPS: 8209 (+)>,
<thread 3 score: 18292638 (+)>,
<thread 3 DMIPS: 10411 (+)>,
<thread 4 score: 17045532 (+)>,
<thread 4 DMIPS: 9701 (+)>,
<thread 5 score: 14150917 (+)>,
<thread 5 DMIPS: 8054 (+)>,
<time: 0.184497 seconds (-)>,
<total DMIPS: 52793 (+)>,
<total score: 92758402 (+)>]
We can also retrieve information about the target that the run was performed on
for example:
.. code-block:: python
# Print out the target's abi:
In [9]: run_output.target_info.abi
Out[9]: u'arm64'
# The os the target was running
In [9]: run_output.target_info.os
Out[9]: u'android'
# And other information about the os version
In [10]: run_output.target_info.os_version
Out[10]:
OrderedDict([(u'all_codenames', u'REL'),
(u'incremental', u'3687331'),
(u'preview_sdk', u'0'),
(u'base_os', u''),
(u'release', u'7.1.1'),
(u'codename', u'REL'),
(u'security_patch', u'2017-03-05'),
(u'sdk', u'25')])
