Hm. My experience with Python for server use tells me that the problem with dynamic languages isn't the primarily the main execution paths, but the exceptional ones. Having to update a server because a request erroneously fails due to a logging statement (or typos in asserts or any other kind of debugging statement) is annoying.
Upon further reflection I think it is important to require logging to be a fail-safe transparent operation (conceptually close to an annotation).
I don't think monitoring statements should be able to cause runtime errors at all.
