Dave have recently found that there are a small collection of EPICs settings that are both NOT touched by Guardian and NOT monitored in the SDF system (see O3SDFReview in the CDS wiki). Today, during the commissioning period, I reviewed and either monitored or justified why to leave them unmonitored for those channels in the SUS models. Below are detailed notes, but the grand summary is that most of those channels can be monitored and were not, to-date, because they were 
    - old defunct channels that are no longer in use and don't impact the IFO, 
    - controlled by another settings channel via the front-end filter modules with control, or 
    - changing them would not affect the IFO in any substantial way. 
The remaining channels that I'm leaving unmonitored are 
    - the OPTICALIGN_$(P/Y)_OFFSET channels which are used for alignment and will necessarily be different from lock stretch to lock stretch
    - the HWWD_STATE channels on the QUADs which are actually readbacks not settings, and are known to be glitchy
    - the violin mode damping filter settings, which can be tuned during observation.

SUS TMSX/Y
    Now monitored.
        H1:SUS-TMSX/Y_COMMISH_$(MESSAGE/STATUS)    (old defunct dummy EPICs variables to indicate that the suspension was in used for aLIGO install testing and commissioning. Doesn't matter at all, so we'll monitor it just to make this check happy.) 
        H1:SUS-TMSX/Y_M1_OPTICALIGN_P/Y_TRAMP      (won't affect anything if changed, but shouldn't be changing, Monitor it just to make the check happy.)
        H1:SUS-TMSX/Y_M1_TEST_P/Y_TRAMP            (won't affect anything if changed, but shouldn't be changing, Monitor it just to make the check happy.)

        H1:SUS-SR2_BIO_M3_$(OSEMDOF)_MSDELAYOFF   (addes a delay to the digital compensation half of turning OFF coil driver switchable frequency response. We want these fixed and monitored.)
        H1:SUS-SR2_BIO_M3_$(OSEMDOF)_MSDELAYON    (same as above, but for turning ON the coil driver switchable frequency response.)
        H1:SUS-SR2_BIO_M3_$(OSEMDOF)_STATEREQ     (master control variable for switching the coil driver frequency response. We want these fixed and monitored.)

        H1:SUS-SR2_M3_EUL2OSEM_TRAMP              (ramp time for the M3 EUL2OSEM matrix. wouldn't affect anything to have it change, but monitor it just to make this check happy.)
        H1:SUS-SR2_M1_LOCK_P/Y_SW1S_INPT          (formerly guardian controlled filter module in filter bank, but shouldn't be changing when in observe, so we want monitored. )
        H1:SUS-SR2_M3_EUL2OSEM_SETTING_$(ROW)_$(COLUMN)  (M3 EUL2OSEM matrix values *to be loaded if load was hit*. Should be fixed in observe anyway, so we want monitored.)

        H1:SUS-ITMY_L2_DRIVEALIGN_$(P/Y)2L_GAIN    (A2L gains. shouldn't be changing during observe anymore, a relic of when we weren't constantly controlling the spot positions on the test masses. Also, not replaced by $(P/Y)2L_SPOT_GAIN, which is already monitored.)
        H1:SUS-ITMY_$(L1/L2/L3)_CAL_LINE_$(CLKGAIN,COSGAIN,SINGAIN,FREQ,TRAMP) (parameters for calibration line injection points. For ITMs we want these OFF and monitored.)

    Still under question (why isn't this touched by the guardian?):
        H1:SUS-ITMY_L2_DAMP_MODE16_SW1S            (filters for control of MODE16 violin mode damping filter. Maybe this mode is no longer in used, or not touched by guardian? Seems like it should be,)
