Eventlog via Proxy - Active Checks

[elias411]

Hello everyone,
We're currently setting up a Zabbix monitoring system and are running into some issues when using active checks via a Zabbix proxy.

Windows Agents Config extract from Location 2:
"Server=" "and ServerActive=" aber bove definded, the IP of the proxy from location 2.
Hostname is also definded,
TLSAccept=psk (tried both psk and unencrypted)
TLSConnect=unencrypted (tried both psk and unencrypted)


Setup:

• Location 1: Zabbix Server (Master), working perfectly.

Here, we are successfully using an active Zabbix agent to, for example, read the Veeam event log:
"eventlog[Veeam Backup,,Information,Veeam MP,190]"
Changes to the polling interval (e.g., from 1m to 20s) take effect immediately and are reflected in the current data.

• Location 2: Zabbix Proxy in use.

Passive checks such as system.cpu.util work without any issues.
However, active checks (like the event log example above) do not work.
Additionally:

• • When we change the interval of an item from 1m to 20s here, it seems to have no effect – it's still only queried every 60 seconds.
  • Even when we try to switch a passive check (e.g., system.cpu.util) to "active," Zabbix shows the change, but it's unclear whether the check is actually running as an active check. We are getting some data back.

You can see in the Docker logs, for example, that a new configuration is received from the server. Likewise, on the other side, it's visible that the configuration is being sent to the proxy.

What are we doing wrong?

Is this an active or passive item?

Even when we try to switch a passive check (e.g., system.cpu.util) to "active," Zabbix shows the change, but it's unclear whether the check is actually running as an active check. We are getting some data back.

If it is configured as active, then it is active, after giving it a few seconds to synchronize the config change all the way to the agent.

Increase the agent DebugLevel to 4 and see the agent log file if you want to see the agent working.

In any case, see the agent log file if you think the agent is not working as expected.

What is your Zabbix version (if it matters in some detail)?

Passive Check

Will Try

What is your Zabbix version (if it matters in some detail)?

Version 7.4.0 via Docker

it's still only queried every 60 seconds

How is the item configured, does it have any preprocessing rule that ignores unchanged values? (= is it not queried or is it not saved)

No preprocessing rule.
