API Shortcut

function returns data owner
sg_get_load_stats sg_load_stats * libstatgrab (thread local)
sg_get_load_stats_r sg_load_stats * caller

The sg_load_stats buffer received from sg_get_load_stats_r() must be freed using sg_free_load_stats() when not needed any more. The caller is responsible for doing it.

On most systems this function is just a wrapper to the getloadavg system call.

The structure returned is of type sg_load_stats.

typedef struct{
        double min1;
        double min5;
        double min15;
        time_t systime;
}sg_load_stats;
The load average over 1 minute.
The load average over 5 minutes.
The load average over 15 minutes.
The timestamp when the above stats where collected in seconds since epoch
