I put in SYSLOG, but I mainly use it to count user QIO's, and to keep the double-word time. I fixed RMDEMO (DEC's copy for 3.2) to use this time counter to display the system up time (RMD starts up on a dedicated CRT when the system boots up). I also use the idle-time count to compute and display the system percent idle time, which gets displayed on line 1 of the RMD screen. Since we lost the rotating lights with the remote front panel, this % display is a handy crutch to see how loaded the system is.
