Adaptive Models in Pega Marketing 7.31 can be monitored in the Analytics Center, see: https://docs-previous.pega.com/pega-marketing-731-release-notes

The best place to check which predictors are never used or always have a low univariate AUC is in the 'Predictors Overview'. See also: https://docs-previous.pega.com/introduction-adaptive-models-reporting-72

Please note that the total list of 30 predictors, is a list of candidate predictors. ADM will decide for itself for each model (proposition) which predictors will become active. For more info, there's a Predictors 101 at: https://mesh.pega.com/docs/DOC-127801

Be careful to withdraw a predictor too quickly because for a proposition you might add in the future it might still have predictive power. I would only withdraw it from the list of candidate predictors if you're sure it's never going to be used. It doesn't do harm to have a larger set of candidate predictors (e.g. 200), although there is a slight performance overhead.
