497*24*3600*100 = 4294080000 is suspiciously around the maximum value that a 32-bit integer can have. Does "uptime" command show the correct value? According to https://www-01.ibm.com/support/knowledgecenter/ssw_aix_71/com.ibm.aix.files/libperfstat.h.htm?lang=en , the type of "lbolt" member in "perfstat_cpu_total_t" structure (which Zabbix uses according to src/libs/zbxsysinfo/aix/uptime.c) is "ime_t", which may or may not be a typo for "time_t". Unfortunately, perfstat is not available on our AIX machines currently. Could you please check the size of "lbolt" on your machine? |
