I realize there are several apps on the market that do this and visualize cycle times for you. I've reviewed most (if not all) of them, and find they're too restrictive. I need to be able to calculate my own fields, values and metrics.
Is there a way, perhaps using ReST APIs, that I can retrieve this data from my portal (or service desk) into a visualization tool or other scheduled output so that I can monitor cycle times myself?
Thanks in advance!
EDIT: Please read the full post - I AM NOT INTERESTED in new gadgets, tools, or add-ons. This limits the functionality that I need, I'm looking for API counsel only. The answer accepted gave me the best input for this (thank you!) but I'd love to hear from non-Atlassian-Partners who have endured this same workaround.
