Problem: Host information was changed (event is triggering with no clear reason)

[boogedy]

Hello,

Please assist.

Zabbix is triggering OS change for Windows Server 2012 with no clear reason.

One message is like that:

---1---
Trigger: Host information was changed
Trigger status: PROBLEM
Trigger severity: Average
Item values:
System information (MYSERVERNAME:system.uname): Windows MYSERVERNAME 6.3.9600 Microsoft Windows Server 2012 R2 Standard
Original event ID: 28555560

And another message comes after 1-2 weeks and says this:

---2---
Trigger: Host information was changed
Trigger status: PROBLEM
Trigger severity: Average
Item values:
System information (AKVALIS:system.uname): Windows AKVALIS 6.3.9600 Microsoft Windows Server 2012 R2 Standard x64
Original event ID: 28555560


What I have done so far?
Reinstalled zabbix client on server - it did not help.

Please kindly assist with the solution, how to stop zabbix triggering and sending unnecessary emails to admins.

What is your Zabbix client version?

Hi Markku!

C:\Program Files\Zabbix Agent>zabbix_agentd.exe --version
zabbix_agentd Win64 (service) (Zabbix) 5.2.0
Revision bcf99fb248 26 October 2020, compilation time: Oct 26 2020 19:45:27

Server version: 5.0.24.

So you are running an ancient .0 version of nowadays unsupported release series, please upgrade the agent to the latest possible level compatible with your Zabbix server.

Hi Markku!

We have server version 5.0.24.
According to this documentation: https://www.zabbix.com/documentation.../compatibility
it is told, that: "Note that Zabbix agent newer than 5.0 cannot be used with Zabbix server 5.0".

I have checked here:

https://www.zabbix.com/download_agents?version=5.0+LTS&release=5.0.24&os=Windows&os_version=Any&hardware=amd64&encryption=OpenSSL&packaging=MSI&show_legacy=0

and is it so, that I have to uninstall agent v5.2.0 and downgrade it to v5.0.24?

I am not expert in zbx, unfortunately.

Yes
