A monitoring process includes a file system representation (FSR) of a file system. The FSR comprises a plurality of nodes corresponding to a respective one of a plurality of elements of the file system. The monitoring process receives a notification of a change to a first element of the file system, caches information associated with a second element of the file system to provide cached information, and processes the FSR in response to the change.
