CPU util monitor is incomplete/broken (1.6.5 agent)

[alj]

Here's my server CPU state (top output):
Cpu(s): 0.0%us, 0.0%sy, 0.0%ni, 0.0%id,100.0%wa, 0.0%hi, 0.0%si, 0.0%st

i e it is waiting for IO
It used to be in 1.4 version that IO wait time was counting as system seems like and system+nice+idle+user were nicely combined produced 100% most of the time.
Now (1.6.5) it is not counting as system and I see weird incomplete stacked CPU load graph where all cpu loads including idle are equal to 0:

# zabbix_get -s h -ksystem.cpu.util[,user]
0.016598
# zabbix_get -s h -ksystem.cpu.util[,idle]
0.000000
# zabbix_get -s h -ksystem.cpu.util[,system]
0.049793
# zabbix_get -s h -ksystem.cpu.util[,nice]
0.000000
# zabbix_get -s h -ksystem.cpu.util[,user]
0.000000
# zabbix_get -s h -ksystem.cpu.util[,kernel]
ZBX_NOTSUPPORTED
# zabbix_get -s h -ksystem.cpu.util[,wait]
ZBX_NOTSUPPORTED
# zabbix_get -s h -ksystem.cpu.util[,interrupts]
ZBX_NOTSUPPORTED
# zabbix_get -s h -ksystem.cpu.util[,interrupt]
0.000000


I think all cpu util loads combined should produce 100% if added otherwise one has no clue where cpu time is going when all metrics are zeroed....

If you're on linux, see function SYSTEM_CPU_UTIL in src/libs/zbxsysinfo/linux/cpu.c:

        if ('\0' == *type || 0 == strcmp(type, "user")) /* default parameter */
                SET_DBL_RESULT(result, collector->cpus.cpu[cpu_num].user[mode])
        else if (0 == strcmp(type, "nice"))
                SET_DBL_RESULT(result, collector->cpus.cpu[cpu_num].nice[mode])
        else if (0 == strcmp(type, "system"))
                SET_DBL_RESULT(result, collector->cpus.cpu[cpu_num].system[mode])
        else if (0 == strcmp(type, "idle"))
                SET_DBL_RESULT(result, collector->cpus.cpu[cpu_num].idle[mode])
        else if (0 == strcmp(type, "iowait"))
                SET_DBL_RESULT(result, collector->cpus.cpu[cpu_num].iowait[mode])
        else if (0 == strcmp(type, "interrupt"))
                SET_DBL_RESULT(result, collector->cpus.cpu[cpu_num].interrupt[mode])
        else if (0 == strcmp(type, "softirq"))
                SET_DBL_RESULT(result, collector->cpus.cpu[cpu_num].softirq[mode])
        else if (0 == strcmp(type, "steal"))
                SET_DBL_RESULT(result, collector->cpus.cpu[cpu_num].steal[mode])
        else
                return SYSINFO_RET_FAIL;

Here's the parameters currently supported.

Oh, thanks for that. I assume then that documentation is outdated....
