1. A system comprising:
a processing device, and
a memory device configured to store a computer program having instructions that, when executed, enable the processing device to
in response to analyzing optical signals propagating in an optical line system, determine whether one or more channels of a spectrum of the optical signals are problematic, whereby the one or more problematic channels are determined to be problematic based on severity of a negative impact that the one or more problematic channels have on spectrum health, the severity determined based on a combination of a plurality of i) overshoot from a target launch power, ii) amount of gain-saturation caused in amplifiers, and iii) amount of tilting caused in the spectrum, and
auto-squelch the one or more problematic channels by replacing the one or more problematic channels with one or more Amplified Spontaneous Emission (ASE) channel holders.
