NAME

rstat, havedisk − get performance data from remote kernel

SYNOPSIS

#include <rpcsvc/rstat.h>
havedisk(host)
char ∗host;
rstat(host, statp)
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.  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];
int dk_xfer[DK_NDRIVE];
unsigned v_pgpgin;/∗ these are cumulative sum ∗/
unsigned v_pgpgout;
unsigned v_pswpin;
unsigned v_pswpout;
unsigned v_intr;
int if_ipackets;
int if_ierrors;
int if_opackets;
int if_oerrors;
int if_collisions;
};
struct statsswtch {/∗ RSTATVERS_SWTCH ∗/
int cp_time[CPUSTATES];
int dk_xfer[DK_NDRIVE];
unsigned v_pgpgin;/∗ these are cumulative sum ∗/
unsigned v_pgpgout;
unsigned v_pswpin;
unsigned v_pswpout;
unsigned v_intr;
int if_ipackets;
int if_ierrors;
int if_opackets;
int if_oerrors;
int if_collisions;
unsigned v_swtch;
long avenrun[3];
struct timeval boottime
};
struct statstime {/∗ RSTATVERS_TIME ∗/
int cp_time[CPUSTATES];
int dk_xfer[DK_NDRIVE];
unsigned v_pgpgin;/∗ these are cumulative sum ∗/
unsigned v_pgpgout;
unsigned v_pswpin;
unsigned v_pswpout;
unsigned v_intr;
int if_ipackets;
int if_ierrors;
int if_opackets;
int if_oerrors;
int if_collisions;
unsigned v_swtch;
long avenrun[3];
struct timeval boottime;
struct timeval curtime;
};
