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.

Return Value

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.
