Zabbix server agent.ping is failing to itself

[moshikoy]

Hi,
My zabbix server is failing to run agent.ping to itself.

root@zabbixsrv:/etc/zabbix# zabbix_get -s zabbixsrv -k agent.ping
zabbix_get [29171]: Check access restrictions in Zabbix agent configuration

On zabbix GUI the server is set to use this interface
192.168.16.121:10050

Zabbix agent config
root@zabbixsrv:/etc/zabbix# cat zabbix_agentd.conf| grep Server
Server=192.168.16.121,127.0.0.1
ServerActive=192.168.16.121


Any idea why is this happening?

I guess that either the name of the host must be in the zabbix_agentd.conf (e.g. Server=192.168.16.121,127.0.0.1,zabbixsrv), don't know if it will work, or use your zabbix_get to 127.0.0.1 (e.g. zabbix_get -s 127.0.0.1 -k agent.ping

Other thing is that if in this case agent is really used in active mode opening passive port is kind of incorrect because:
- active monitoring is used to have better scaleability
- active mode is used to use secure monitoring strategy (communication is only allowed from agents to serve/proxies) and in such case keeping allowed traffic in reverse direction violates what active monitoring gives.

If rally in this case is used active monitoring using agent.ping item should be dropped.

Thanks for all your help
it appears that zabbix_get was version 3.4 while zabbix server/agent is 4.0.2
after upgrading zabbix_get the issue resolved
