To get simple information from a workflow, such as the name, run start date/time and run end date/time is far more complex than it should be. Ideally the log, in separate line items distinctly labelled, would have the workflow path & name, the start date/time, and end date/time and potentially the run time to save having to do a calculation. Also having an overall module status would be of use, i.e. if there was an Error in the run the overall status is Error, if there was a warning the overall status is Warning otherwise Success.
Parsing out the workflow name and start date/time is challenge enough, but then trying to parse out the run time, convert that to a time and add it to the start date/time to get the end date/time makes retrieving basic monitoring information far more complex than it should be.
