Triggered task POSTed parameters - how to view in execution statistics/logs

Thanks both, is there nothing out of the box that allows us to view the payload - from the logs or monitoring? 

To give some context I'm simply trying to troubleshoot pipelines called via triggered tasks and would like to determine what values are being passed in to assist with this.  I have many of these pipelines and want to avoid having to create  database for these to all write to - i'm quite surprised this functionality isn't built-in.

Thanks
