- .SH NAME
- sysstat \- print statistics and information about the state of the system
- .SH SYNOPSIS
- \fBsysstat \fR[\fB\-vcR\fR]
- .SH OPTIONS
- .IP "\fB\-v\fR" 14
- Print out the compilation version timestamp for the kernel. This is
- the default if no options are specified.
- .IP "\fB\-c\fR" 14
- Print out the number of times each system call has been invoked.
- .IP "\fB\-p\fR \fIn\fR" 14
- Enable or disable system call timing.
- .IP "\fB\-t\fR" 14
- For each system call, print the number of calls and how much time was
- required.
- .IP "\fB\-R\fR" 14
- Reset the count and time information for system calls.

- .SH DESCRIPTION
- .LP
- This command prints out statistics and other information about the
- system.
- .SH "VERSION TIMESTAMP"
- .IP "\fB\-v\fR"
- By default, \fBsysstat\fR prints the compilation version timestamp for the
- kernel. This is a unique identifier indicating who compiled the
- kernel and when. This information is printed if no options are
- specified, or if the \fI-v\fR option is specified.
- .SH "SYSTEM CALL STATISTICS"
- .IP "\fB\-c\fR"
- This option indicates that \fBsysstat\fR should display a count of the
- number of times each system call has been invoked. For each call, the
- number of invocations is printed along with an indication of whether
- the call, if done by a migrated process, would be handled locally or
- would require action by the process's \fIhome node\fR.
- .IP "\fB\-t\fR"
- This option tells
- .B sysstat
- to display for each system call the number of times the call was
- invoked, the total time spent in that call, and the average time spent
- in that call. Note that if a process is migrated, its system calls
- are recorded by the host that it is executing on, rather than by the
- home node. Normally system call timing is turned off; use the
- .B \-p
- option to turn it on.
- .IP "\fB\-R\fR"
- This option causes \fBsysstat\fR reset the kernel's count of the
- number of times each system call has been invoked, as well as the
- accumulated time for each system call. Thus, subsequent invocations of
- \fBsysstat\fR with the \fB\-c\fR or \fB\-t\fR option will report only
- activity since the invocation with the \fB-R\fR option.
- .IP "\fB\-p\fR"
- This option controls whether Sprite keeps track of how much time each
- system call takes. To turn on system call timing, use
- .BR "\-p 1" ;
- to turn it off, use
- .BR "\-p 0" .
- .SH BUGS
- System call timing is only available on ds5000s.
- .SH "SEE ALSO"
- migcmd, fscmd
- .SH KEYWORDS
- statistics, process migration, system call

- This option causes \fBsysstat\fR to perform a system call to reset the
- kernel's count of the number of times each system call has been
- invoked. Subsequent invocations of \fBsysstat\fR with the \fI-c\fR option
- will report the count of calls since the invocation with the \fI-R\fR option.
