1. A method for monitoring downhole, comprising:
routing a hydraulic control line to a downhole tool to enable hydraulic actuation of the downhole tool;
connecting a downhole pressure gauge to the hydraulic control line at a downhole location such that the downhole pressure gauge is less than 100 feet from the downhole tool;
determining a baseline pressure profile with respect to operation of the downhole tool by measuring pressure in the hydraulic control line during testing or initial operation of the downhole tool, wherein normal operation of the downhole tool provides the baseline pressure profile; and
using data from the downhole pressure gauge in comparison with the baseline pressure profile to identify deviations from the baseline pressure profile to determine operational characteristics of the downhole tool and for pre-failure identification.
