[MONRPT.HLP; 24-Nov-82]
The MONRPT (MONitor RePorT) program produces a brief operating system
performance report. It is invoked by the monitor command "R MONRPT". At startup
time it writes several lines of information including a set of column labels
(listed below). Thereafter, at intervals of approximately one minute, it outputs
a single line of monitor performance data.
Normally, the output is typed on the user's terminal. However, if device DSK has
the logical name "MONRPT", the data will be appended to the file MONRPT.RPT. If
necessary, a new file will be created. The reported quantities are:
daytime time-of-day
runtime elapsed time since program began execution
intrvl seconds since previous report
mem total physical system memory (pages)
user total physical user memory (pages)
virt total virtual user memory (pages)
job number of jobs
usr user time (percent consumed by users)
ovr overhead time (percent consumed by monitor overhead)
nul null time (percent not consumed)
idl idle time (percent not consumed, nothing to do)
lst lost time (percent not consumed, runnable jobs not in memory)
resp number of execution responses
mean mean response time (seconds)
var variance in response time (seconds)
