Running validation sanity check only

Hi all, I’m new to pytorch lightning here.

I want to get all of the logged value before actually running the training, as I understand it currently one way to do this is to run validation sanity check. But I could not find any documentation stating how to run it without
is it possible to run only the validation sanity check without running or is there a better way to get all the logged value from LightningModule without running the entire training pipeline?
