DNS name instead of ip address for SERVER parameter in agent conf

[zabbixfk]

Hello All,

Wanted just a clarification/understanding of SERVER= parameter in zabbix_agentd.conf. I am able to get the values only if i pass ipaddress of the zabbix server against dns name. Is there any way to get this working ( i tried replacing ip address to dns name, but was not getting any values on zabbix UI, even zabbix get got failed.)

Has anybody got this working ? ( Was looking at building DR, and can't afford to hardcode/static ipaddress in agent conf files)

Please share your pointers/inputs.

Thanks.

Thanks for the reply. Yes DNS resolve perfectly works fine.

i believe hostnames should work as well as ip addresses:

https://www.zabbix.com/documentation/2.0/manual/appendix/config/zabbix_agentd

something strange in the agent log file?

Some notes from documentation:

List of comma delimited IP addresses (or hostnames) of Zabbix servers. No spaces allowed.
Incoming connections will be accepted only from the hosts listed here.
Note that hostnames must resolve hostname→IP address and IP address→hostname.

Please, check both DNS resolving.
You can use DebugLevel=4 to get more information in zabbix-agent.log files

Sorry, my bad !!!

Though DNS was resolving from agent ( linux machine ), firewall was enabled ( iptables ) : which was blocking both internal/external connections on specific ports ( 10050/51 ).

This link helped to add iptable rules


Thanks.
