[en] A comprehensive system accounting package for RSX11M V3.2 offering users similar functionality to that available on RSX11M is presented. Although it was primarily implemented to monitor and collect system performance statistics, user by user statistics adequate for implementing chargeback accounting system are also acquired. System wide statistics include: CPU idle time, number of checkpoints, number of loader requests, number of QIO's, number of taks in and out of core, and pool usage parameters. Optionally, user selected tasks may be monitored for CPU time and QIO's. On a per user basis, CPU time, terminal connect time, QIO's, and number of pages spooled to printers, and a number of tasks run are accounted for. In addition, disk block accounting may be enabled on a per user basis. This package requires minor executive modifications and a SYSTEM generation to implement. However, it has been extensively field tested and has been found easy to implement by a large number of users. This software is available free through the RSX SIG and DECUS
