class lisa.wa.WACollectorBase(wa_output, df_postprocess=None)

Bases: StatsProp, Loggable, ABC

Base class for all Workload Automation dataframe collectors.

Parameters:

• wa_output (WAOutput) – WAOutput parent object.

• df_postprocess (collections.abc.Callable) – Function called to postprocess the collected pandas.DataFrame.

See also

Instances of this classes are typically built using WAOutput.get_collector() rather than directly.

df	pandas.DataFrame containing the data collected.
logger inherited	Convenience short-hand for self.get_logger().
stats inherited	Short-hand property equivalent to self.get_stats().

Methods

get_logger() inherited	Provides a logging.Logger named after cls.
get_stats() inherited	Returns a lisa.stats.Stats loaded with the result pandas.DataFrame.
log_locals() inherited	Debugging aid: log the local variables of the calling function.
