Note that these values imply powers of two in numbers of bytes.
When using file transfer concurrency limits, the following additional I/O usage statistics are published. These includes the sum and rate of bytes transferred as well as time spent reading and writing to files and to the network. These statistics are reported for the sum of all users and may also be reported individually for recently active users by increasing the verbosity level STATISTICS_TO_PUBLISH = TRANSFER:2. Each of the per-user statistics is prefixed by a user name in the form Owner_<username>_FileTransferUploadBytes. In this case, the attribute represents activity by the specified user. The published user name is actually the file transfer queue name, as defined by configuration variable TRANSFER_QUEUE_USER_EXPR . This expression defaults to Owner_ followed by the name of the job owner. The attributes that are rates have a suffix that specifies the time span of the exponential moving average. By default the time spans that are published are 1m, 5m, 1h, and 1d. This can be changed by configuring configuration variable TRANSFER_IO_REPORT_TIMESPANS . These attributes are only reported once a full time span has accumulated.
