Problem - iowait does not work with zabbix-agent 1.8.3 and 1.8.4.

[rozie]

Hello.
I use zabbix-server version 1.8.4 on 64bit OS. I noticed, that
zabbix_get -s <IP> -k system.cpu.util[all,iowait,avg15]
returns always: 0.000000 for zabbix-agent version 1.8.4. The same happens after downgrade to 1.8.3. Downgrade zabbix-agent to 1.8.2 solves the problem - looks like something got broken on 1.8.3.

PS. Any way to report such a bug without having support?

Regards,
rozie

What operating system are you using?

Try

zabbix_get -s <IP> -k system.cpu.util[,iowait]

[root@mon etc]# /opt/zabbix/bin/zabbix_get -s 127.0.0.1 -k system.cpu.util[,iowait]
46.748170
[root@mon etc]# /opt/zabbix/bin/zabbix_get -s 127.0.0.1 -k system.cpu.util[all,iowait]
46.627298
[root@mon etc]# /opt/zabbix/bin/zabbix_get -s 127.0.0.1 -k system.cpu.util[all,iowait,avg15]

I's the same (0.000000) with suggested zabbix_get -s <IP> -k system.cpu.util[,iowait]

System is Debian Lenny with distribution kernel:
2.6.26-2-amd64 #1 SMP Thu Sep 16 15:56:38 UTC 2010 x86_64 GNU/Linux

The same happens on Debian Squeeze with distribution kernel:
2.6.32-5-amd64 #1 SMP Wed Jan 12 03:40:32 UTC 2011 x86_64 GNU/Linux

In both cases downgrade zabbix-agent to 1.8.2 helped.
