Zabbix names discovered hosts with IP instead of hostname

[fsousa]

I'm installing a fresh zabbix 3.2 on centOS 7.
I've enabled discovery rule for my network and setting device uniqueness criteria to system.uname. Also, I've activated the built-in action to assign Linux machines to appropriate host group.

Now the zabbix server discover a second machine configured as zabbix client, but uses the IP instead of hostname for host's Host name attribute.

How I cant configure zabbix to display hostname instead of IP for discovered hosts?

Thanks!

You mean that you've enabled Configuration -> Actions -> Discovery ?

Unfortunately you can't do it this way, because your server needs to resolve the ip address to hostname.

If you want to use zabbix agent.hostname value - use auto-registration feature ( https://www.zabbix.com/documentation...o_registration ) or comment out the Hostname= line and use HostnameItem=system.hostname default item if you want to use your Hosts hostname.

Hello Alexey,

Thank you for your reply.

Now my client have the line Hostname commented and HostnameItem=system.hostname uncommented. Now I have to disable my discovery rule and create a auto-registration action?

Thank you.

Yes, create just basic auto-registration rule. Skip conditions and just configure the Operations tab with appopriate Host Group, Template and Add Host parameters.

Have you configured Zabbix Agent with ServerActive parameter ? Can you connect from host to the server using port 10051 ?

That's it, my port 10051 in zabbix server wasn't open. Now its running perfect, and already discovered my two clients I have to test. Perfect.

Now when I go to this hosts the agent interface show the IP Address, can I configure to put the DNS name?

Thank you.

In this case I can say that you can try nad if what - put the Ip address back, but make sure your host is discoverable via name to server, otherwise there will be no connection

The hos t is discoverable via name, because in server appears the name of the host like the first image. But when I go to host configuration on Agent interfaces only appears the IP address (second image) and I want field the DNS name automatically if possible.

Thanks.
