Data from Zabbix Proxy not reported to Zabbix server

[rvreugde]

Hello,

We have the following configuration:

• We have a network configuration with a lot of VLAN's.
• One Zabbix server (CentOS8.x/ Zabbix 5.4.x) is installed and configured.
• In each VLAN, we have a Zabbix Proxy (CentOS8.x/ Zabbix 5.4.x) configured, which reports to the Zabbix Server. All systems in the same VLAN report to their data to the corresponding Proxy.
• Ports 10050/10051 are opened.

We encounter a problem in one of VLAN's

• The proxy reported to the Zabbix server
• All agents are also visible in the Zabbix server
• But, no data is reported from any agent

Is there any way to troubleshoot this problem?:

• How can we see if any data from an agent is reported to the proxy?
• Can we check if this data is indeed accepted/stored in the database of the proxy?
• Is it possible to check if the data is send to the Zabbix server (or can we force this)?

Thanks a lot for your help and answers!


Regards,

Raf

Hi Raf

Have you checked the timeout in the zabbix agent configuration? Usually this is a firewall or network related issue but the agent timeout could be crucial too.

The timeout parameter was set to a value of 10. This solves the problem.
Thanks Eli for your golden tip!
