    Trying to get free [1] command working [2] inside of a OmniOS zone. free implementation is using kstat internally.

    pagesize = getpagesize();
    pages = sysconf(_SC_PHYS_PAGES);
    total = pagesize * pages;

    zoneid_t zid = getzoneid();
    if (zid > 0) {
    	/* local zone */
    	 ks = kstat_lookup(kc, "memory_cap", zid, NULL);
    	 kstat_read(kc, ks, 0);
    	 knp = kstat_data_lookup(ks, "rss");
    	 if (knp == NULL) {
    		(void) kstat_close(kc);
    	 	 return (-1);
    	}
    	used = (unsigned long long)knp->value.ui64;
    	freemem = total - used;
    }

    It seems that memory_cap is SmartOS only.

    Any idea what can be used instead on OmniOS?

    Best regards
