Submodules

manafa.parsing.hunter.AppConsumptionStats module

class manafa.parsing.hunter.AppConsumptionStats.AppConsumptionStats(results_dir='/Users/ruirua/repos/emanafa/manafa/results/consumptions')

Bases: object

Class that stores method traces of apps registered with hunter.

This class parses and batterystats history events from files parsed using parseFile function. It starts by load information contained in the device power profile file and also the current state values known by the profiler, stored in definitions attribute.

app_traces

method traces.

Type

dict

results_dir

results’ directory.

Type

int

clean()

clears app_traces attribute.

get_output_filepath(test_id)

gets path of output file where the consumption info will be written. :returns: filepath :rtype: str

save_function_info(filename, filter_zeros=False)

save method traces contained in app_traces to file. :param filename: name of output file. :param filter_zeros: filter zeros

Returns

path of the output file

Return type

str

static write_consumptions(filename, consumption, function=None)

writes consumption info to file. :param filename: path of output file. :type filename: str :param consumption: consumption value. :type consumption: float :param function: option function name if the consumption is from a function.

manafa.parsing.hunter.HunterParser module

class manafa.parsing.hunter.HunterParser.HunterParser(boot_time=0)

Bases: object

Class that parses traces in log files generated by a custom hunter plugin.

This class parses method traces contained in log files generated by a custom hunter plugin.

trace

method traces.

Type

dict

boot_time

timestamp of the device’s last boot.

Type

float

end_time

timestamp of the last trace.

Type

float

add_consumption(function_name, position, consumption, per_component_consumption, metrics)

updates consumption stats when a line referring a function is parsed. :param function_name: name of the function to update. :param position: index in stats. equivalent to number of function calls so far. :param consumption: consumption value. :param per_component_consumption: consumption per component. :param metrics: batterystats during function execution.

add_cpu_consumption_to_trace_file(filename, functions, instrument=False)

parse_file(filepath, functions, instrument=False)

function to parse traces from filepath file. :param filepath: logfile with app traces. :param functions: list of function names to filter. :param instrument: optional paramm to enable or disable function filtering.

parse_history(lines_list, functions, instrument=False, start_time=0, end_time=9223372036854775807)

function to parse app traces from a list of lines (lines_list). :param lines_list: list of lines from log file. :param functions: list of function names to filter. :param instrument: optional paramm to enable or disable function filtering. :param start_time: lower timestamp bound. :param end_time: upper timestmp bound.

return_cpu_consumption_and_time_by_function(function_name, checked)

returns energy consumed and elapsed time of function with function_name- :param function_name: name of the function. :param checked: if the start and end time of the function was determined.

Returns

da_time:

Return type

cpu_consumption

update_trace_return(function_name, end_time)

updates function return time. :param function_name: name of the function. :param end_time: function end time.

static verify_function(function_name, functions, add_function=False)
