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. For example, if you are on system \BWS1 and want to see the file level activity across Expand, you would enter in the File Name field \BWS2.$*.*.* .
