The Files / File Entity screen presents the MEASURE File Entity.
The MEASURE File entity is I/O activity on a file. A file is a communication path from one process to another and is not necessarily to a disk file. This entity is unique with its ability to track and report on all sorts of different I/O activity from inter-process, TCP/IP, OSS and process to disk.
The File entity is measured from the perspective of the opener. A process on a remote system opening a local file cannot be measured on the local system using this entity. A local process opening a remote file can be measured locally.
