PhixFlow generates processing statistics which are saved to the database. These statics are for use by administrators and designers who are tuning for performance.

See System Configuration for how to enable and manage stats generation.

Database Statistics Record Structure

The table structure for STATS is as follows:

Member	Class	Description
stats_type	enum	Statistics Type: E.g. 'Activity, Pipe, PipeLookup, PipeQueue, Stream'
fromDtm	Datetime	The start time of the period that this measure refers to
toDtm	Datetime	The end time of the period that this measure refers to
initiator_type	String	The object initiating the activity - eg. "TaskPlan", or "Action"
initiator_id	Uid	The ID of the initiating TaskPlan or Action / other object.
initiator_name	String	The name of the initiating TaskPlan or Action / other object.
context_type	String	The activity triggered by the initiator. eg "Stream"
context_id	Uid	e.g. The "Streams" ID that Analysis was run on.
context_name	String	eg. The name of the stream that Analysis was run on.`
full_context	String	This a dotted notation indicating the full context. eg. TaskPlan1.Stream X.in
data_type	String	The type of statistics data being recorded for this stats type. Eg. totalRecordsWritten, totalWriteTime.
data_value	Double	The value of the statistic being recorded for the given data_type.
