server failed to connect to agent (Active checks)

[timypcr]

Why does the server still try to connect to the agent when the agent has been configured with active checks only (StartAgents=0)I'm attempting to monitor agents over the Internet (agents and server not in same location) I followed this https://www.fontenay-ronan.fr/zabbix...-nat-firewall/ but the status for ZBX is red with error Get value from agent failed: cannot connect to [[0.0.0.0]:0]: [111] Connection refused I'm just not sure why the server is even trying to connect to the agent with this conf https://gist.github.com/95ff31d16584...253f221317ea4I thought the point for active checks was to not have to worry about NAT/port forwarding on the agent side?

Any help would be great, this is my first time with zabbix and I've been stuck on this for 5 hours. If this is due because passive checks are stills setup please advise how I would remove all remaining passive check, does section 3.1 Prepare the template of the blog I posted above not do this?

Cannot connect to agent

Same problem here. I have configured the agent for actice checks and it seems that agent has a connection with the server.

/var/log/zabbix/zabbix_agentd.log:

14181:20180206:103051.352 In send_buffer() host:'xxx.xxx.xxx.xxx' port:10051 entries:0/100
 14181:20180206:103051.352 End of send_buffer():SUCCEED
 14181:20180206:103051.352 __zbx_zbx_setproctitle() title:'active checks #1 [idle 1 sec]'

 14180:20180206:103051.653 End of update_cpustats()

Server side I get the following error:

Get value from agent failed: cannot connect to [[127.0.0.1]:10050]: [111] Connection refused

How can I define a host without setting a agent interface (and unreachable ip) for it?

Help is needed!

It seems the problem was how the item types in templates were defined. Item types need to be set to 'Zabbix agent (active)' to work with active agents.

See https://www.fontenay-ronan.fr/zabbix...-nat-firewall/

Edit. I also enabled active agent auto-registration. Not sure if it makes any difference here.

Two possibilities:
1) you are trying to use agent.ping[] key to check is it possible to connect with the agent when the agent in active mode by definition is not listening on 10050/tcp.
2) some of the items used on this host are not "zabbix agent (active)" type but still passive items ("zabbix agent" type).
