Auto registration help

[symfrog]

Hi

I just dowloaded and installed 1.8 stable, mainly for the auto registration support (running on ec2). There isn't too much documentation on it in the user manual or on the forums.

So I went ahead and assumed that all I needed to do was add an "Auto Registration" action. Which I did, unfortunately it seems that the action is never triggered for new agents. I checked the logs on both the agent and server and didn't see anything related to auto registration, also checked conf files for a possible setting.

Auto discovery on the same agents work fine (with the same operations on the action). Can anyone let me know how to get auto registration working?


Thanks

[richlv]

could you show the action properties ?
are active checks enabled on agents ?
do you see them connecting to the server in the server logfile ?

Here is the agent log:

 8233:20091208:124610.869 zabbix_agentd started. Zabbix 1.8 (revision 8565).
  8235:20091208:124610.895 zabbix_agentd collector started
  8236:20091208:124610.914 zabbix_agentd listener started
  8238:20091208:124610.950 zabbix_agentd listener started
  8239:20091208:124610.969 zabbix_agentd listener started
  8240:20091208:124610.989 zabbix_agentd active check started [192.168.1.53:10051]

As mentioned if I use auto discovery it all works fine, the problem only happens with auto registration.


Here is my zabbix_agentd.conf:

I have attached a screen shot of the Auto registration action.

[richlv]

ah, but the host is already created in zabbix ?
if so, i believe no autoregistration event will be generated - that is only generated when an unknown host contacts zabbix server

[symfrog]

No, the host was not already created. This was a completely fresh install of both the server and the agent.

Also tried it with several other hosts, same issue.

[richlv]

hmm. then i suppose you are missing actual operation 'add host'

[symfrog]

No, Same operations adds the host fine with auto discovery. I think active checks may be the problem, will take a closer look.

[richlv]

hmm, the operation should be more or less the same - please register this on the tracker

[symfrog]

Got it working. I think it relates to active checks. I had to set the hostname={agent hostname} in zabbix_agentd.conf

Is there a way during auto discovery/auto registration to tell the server to connect to agent using IP instead of dns name (as is possible when manually adding a host)? I would prefer not to have to update dns/hosts on server for each add agent.

[richlv]

well, yes, auto-registration basically happens when active zabbix agent connects to the server - so that has to be working.

not sure about setting hostname/ip, that might be a feature request - file it on the tracker

Bumping an old topic

I'm having this trouble too. Our hostnames are set to tell Zabbix what the role is (and consequently add it to groups, templates, etc). However, the hostname is not a FQDN though zabbix treats it as such.

How can I let auto-discovery know the private ip address for the server in the config?
