1. A system for controlling hydraulic pressure at a swage tool, the system comprising:
a pressure sensor configured to monitor hydraulic pressure of a tool that is installing a fastener; and
a controller configured to detect that the hydraulic pressure has dropped by more than a threshold amount within a period of time, determine that a pintail of the fastener has snapped in response to the detecting, automatically reduce the hydraulic pressure in response to the determining, and confirm a state of the fastener based on additional monitoring of the hydraulic pressure.
