These are collected on two different clouds, one performing many ironic operations constantly as a benchmark, one simply left alone over the weekend. Resets line up with restarting the ironic conductor service, these are stock TripleO deployments with Newton, nothing special required to reproduce.
If you zoom in some it seems to be related to periodic conductor tasks like updating node status.

This dashboard shows a very slight upward trend in average introspection times as the cpu load trends up. About 30 seconds, so you'd be hard pressed to call it a serious performance issue at this point, but if the trend continues over lets say a couple of months it would be concerning.
