From my experience, story points work best for user stories. So what about other issue types? In past teams (and the current one), we've had success with time-boxes, especially for "spike solution" tickets. However we're experimenting with time-boxes for ticket types such as tasks (and potentially, bugs).
Is there a way to track a second velocity metric in Jira (in our case, a time-based one)?
Also, what are peoples' opinions on such a practice? Any comments / concerns?
