beostat_get_last_multicast – get file system statistics for the root file system on a node
#include <sys/beostat.h> time_t beostat_get_last_multicast (void);
beostat_get_last_multicast executes on the master node and returns
the time of the last multicast request sent to the nodes. It is usually
reserved for internal use.
Returns the time in seconds since Epoch (00:00:00 UTC, January 1, 1970) of the last multicast request. If an error occurs, it will return -1.
This function relies on the
Beostat subsystem, which consists of the
proc filesystem on the remote node, the
sendstats daemon on the
remote node, the
recvstats daemon on the master node, and two shared
memory files in the directory
/var/shm. If any part of the system
breaks down, this function could fail.
