 rstat(3N)                                                         rstat(3N)





 NAME
      rstat(), havedisk() - get performance data from remote kernel

 SYNOPSIS
      #include <time.h>
      #include <rpcsvc/rstat.h>

      int havedisk(char *host);

      int rstat(char *host, struct statstime *statp);

 DESCRIPTION
      havedisk() returns 1 if host has a disk, 0 if it does not, and -1 if
      this cannot be determined.  The host string is either the official
      name of the host or an alias for it.  See hosts(4) for more
      information regarding host names.

      rstat() fills in the statstime structure for host, and returns 0 if it
      was successful.  The relevant structures are:

           struct stats {               /* RSTATVERS_ORIG */
               int cp_time[CPUSTATES];  /* the time spent in each CPU state */
               int dk_xfer[DK_NDRIVE];  /* total number of disk transfers
                                           on each of the disk interfaces */
               unsigned v_pgpgin;       /* total VM pages paged in */
               unsigned v_pgpgout;      /* total VM pages paged out */
               unsigned v_pswpin;       /* total VM pages paged swapped in */
               unsigned v_pswpout;      /* total VM pages paged swapped out */
               unsigned v_intr;         /* total interrupts */
               int if_ipackets;         /* inbound packets on all interfaces */
               int if_ierrors;          /* inbound errors on all interfaces */
               int if_opackets;         /* outbound packets on all interfaces */
               int if_oerrors;          /* outbound errors on all interfaces */
               int if_collisions;       /* collisions seen on all interfaces */
           };

           struct statsswtch {          /* RSTATVERS_SWTCH */
               int cp_time[CPUSTATES];  /* the time spent in each CPU state */
               int dk_xfer[DK_NDRIVE];  /* total number of disk transfers
                                           on each of the disk interfaces */
               unsigned v_pgpgin;       /* total VM pages paged in */
               unsigned v_pgpgout;      /* total VM pages paged out */
               unsigned v_pswpin;       /* total VM pages paged swapped in */
               unsigned v_pswpout;      /* total VM pages paged swapped out */
               unsigned v_intr;         /* total interrupts */
               int if_ipackets;         /* inbound packets on all interfaces */
               int if_ierrors;          /* inbound errors on all interfaces */
               int if_opackets;         /* outbound packets on all interfaces */
               int if_oerrors;          /* outbound errors on all interfaces */
               int if_collisions;       /* collisions seen on all interfaces */
