no active checks on server [SIP:10051]: host [platform-ovh] not found

[richard.murray]

Please can somebody explain why Zabbix does not work how I expect it to please!

When I start an agent it will contact to the server and the "platform-ovh" host will be created via autodiscovery.

Then the agent will log "no active checks on server [IP:10051]: host [platform-ovh] not found".

But the agent just caused the "platform-ovh" host to be created on the server with the name "platform-ovh" using auto discovery!!!

Agent log;

Hi,

Are you using Action with even source "Discovery" or "Auto registration" to register Zabbix agent? In this setup I would to suggest to go with "Auto registration".
Please share the info how you implemented configuration under "Operation" tab.

Hi.

Zabbix 3.4 running in K8S.

Configured as AutoDiscovery;

Configuration->Action
Action : Host metadata like Linux
Operations : Add Host, Add to host groups Linux Servers, Link to templates Template OS Linux

If I;

Stop the agent.
Delete the Host.
Start the agent.
The Host is created but Availability ZBX goes red and reports "Get value from agent failed: cannot connect to [[IP]:10050]: [4] Interrupted system call"

IP has been removed.

What/Where is the "Operation" tab?

Thx...

Get value from agent failed: cannot connect to [[IP]:10050]: [4] Interrupted system call

The message indicates that the server cannot connect to the agent through port 10050. Please test from server side:

nmap -p 10050 ip.address.of.client

Another workaround is to use only active items. This means you need to convert all items from "zabbix agent" to "zabbix agent-active".

"message indicates that the server cannot connect to the agent through port 10050" checked through the templates and one of them was Zabbix Agent not Zabbix Agent Active hence the red ZBX.

Thank you!
