rstat, havedisk - get performance data from remote kernel
cc [ flag ... ] file ... –lrpcsvc [ library ... ] #include <rpc/rpc.h> #include <rpcsvc/rstat.h> enum clnt_stat rstat(char *host, struct statstime *statp);
int havedisk(char *host);
These routines require that the rpc.rstatd(1M) daemon be configured and available on the remote system indicated by host. The rstat() protocol is used to gather statistics from remote kernel. Statistics will be available on items such as paging, swapping, and cpu utilization.
rstat() fills in the statstime structure statp for host. statp must point to an allocated statstime structure. rstat() returns RPC_SUCCESS if it was successful; otherwise a enum clnt_stat is returned which can be displayed using clnt_perrno(3NSL).
havedisk() returns 1 if host has disk, 0 if it does not, and −1 if this cannot be determined.
The following XDR routines are available in librpcsvc:
