FSTAT.USER

The FSTAT.USER command shows a periodically updated report of file access statistics on a per-user basis.

Format

FSTAT.USER

QM maintains file activity counters that record the number of opens, reads, writes, deletes, etc. The FSTAT.USER command displays the statistics on a per-user basis, allowing identification of processes that might be performance bottlenecks. Used in conjunction with other analysis tools, a developer can identify exactly where the file activity is concentrated.

The FSTAT.USER command initially shows a screen that shows the user number, user name and read/write/delete counts in user number order for as many users as will fit on the screen. Entering the letter "T" switches to "top mode" in which the report is sorted into descending order of file activity. Entering "T" again reverts to the default sequencing.

The display is updated periodically, every two seconds by default. The update interval can be changed to any value in the range 1 to 3600 by entering "I" followed by the desired interval value.

Entering "D" toggles "difference mode" in which each display update shows the activity since the last update.

 27  SARAH             1809       213          1

Entering "U" followed by a user number shows a detailed report for that user.
