mpstat
— Prints DECmpp Sx job accounting statistics, Version 1.1
Syntax
mpstat [
options]
Description
The
mpstat
command examines, and optionally clears, the accounting file
generated by the
dpumanager(8)
program. Depending on the options specified, it
prints a list of all jobs run and/or a summary.
Options
-a
Use this option to request a chronological list of all of the relevant jobs listed in
the accounting file. The job starting time, user name, process id, running time
and waiting time is printed for each job. Waiting time includes time waiting for
access, time when a job is swapped out, inactive periods after the job has released
the data parallel unit (DPU) but has not closed the device, and a small amount of
system overhead.
-c
Use this option to request the accounting file to be cleared at the end of the
program.
-f
file
Use this option to specify the name of an accounting file to be used in place of the
default.
-s
Use this option to request a summary showing the number of jobs, the average
and maximum running times, and the average and maximum wait times. This is
the default when neither the -a nor -c options are specified.
-t
job_count
Use this option to specify that only the tail job_count entries in the accounting
log are of interest. This allows you to see only the most recent log entries. Note
that other filters (like the -u option) are applied after this one, so you may see
less than the specified number of entries. This option may be used with both the
-a and -s options.
-u
userName
Use this option to cause
mpstat
to only count jobs for the specified user (login
name).
Restrictions
The accounting file may only be cleared when you are running
mpstat
as root.
