.\" @(#)rpc.rstatd.8c 2.2 88/08/03 4.0 RPCSRC; from 1.10 87/09/09 SMI
.TH RPC.RSTATD 8C "24 November 1987"
.SH NAME
rpc.rstatd \- kernel statistics server
.SH SYNOPSIS
.B /usr/sbin/rpc.rstatd
.SH DESCRIPTION
.LP
.B rpc.rstatd
is a server which returns performance statistics
obtained from the kernel.
These statistics are read using the
.BR rup (1)
command.
The
.B rpc.rstatd
daemon is normally invoked through /usr/sbin/inetd.
.PP
.B rpc.rstatd
uses an RPC protocol defined in /usr/include/rpcsvc/rstat.x.
.SH "SEE ALSO"
.BR rup (1),
.BR inetd (8),
