Zabbix agent (active mode) on Windows has sent wrong data...

[tom8254]

the item key is directory size of a folder in Windows device.

but the zabbix agent keep sending wrong data and correct data.

I don't know why the zabbix agent keep sending once wrong data and once correct data.

Zabbix server has free memory more than 4 GB and total 6GB.
The windows device has free memory 2.4GB of 4GB.

When I collect date using zabbix_agentd -t on the Windows device, it is always correct.

Someone guess what it is problem? or give me advise to resolve this problem.

Thank you

Zabbix server version : 3.4.11
Zabbix agent version on windows device : 3.4.6

I've check zabbix agent using debug mode level 5 and zabbix agent keep sending 0 value not another value......how do I do?

Solved after changing passive mode.

Looks like you have 2 hosts with identical Hostname= in Agent configuration file.
So you are receiving values from two servers under one item.

Yeah You are correct.
I've checked configuration file and it was same host name.

Thank you for your advise.
