+.Nm rpc.rstatd 
+.Nd kernel statistics server
+.Sh SYNOPSIS
+.Nm /usr/libexec/rpc.rstatd
+.Sh DESCRIPTION
+.Nm rpc.rstatd
+is a server which returns performance statistics obtained from the kernel.
+These statistics are read using the 
+.Xr rup 1
+command.
+The
+.Nm rpc.rstatd
+daemon is normally invoked by
+.Xr inetd 8 .
+.Pp
+.Nm rpc.rstatd
+uses an RPC protocol defined in 
+.Pa /usr/include/rpcsvc/rstat.x .
