Auto Discovery not working as expected

[r0k5t4r]

Hi,

we are currently evaluating zabbix 1.6 for our network. I have setup 3 Auto discovery rules and none of them seem to be working correctly.

From the manual it says that discovery is the first part and then an action can take place. I used the preconfigured actions to add discovered machines with a zabbix client installed.

My discovery looks like this:

IP Range: 172.20.205.1-255
Delay: 600

Checks: Zabbix agent
Status: active

I can also see in the zabbix-server.log that the discovery is running:

[172.20.200.189]:10050 [No route to host]
6284:20090603:135158 Get value from agent failed. Error: *** Cannot connect to [vb5891.vegagroup.net]:10050 [No route to host]
6298:20090603:135159 Get value from agent failed. Error: *** Cannot connect to [172.20.200.190]:10050 [No route to host]

i installed an agent on 172.20.205.8 and i can successfully manually add it to the hosts. But the action combined with the discovery doesn't seem to work.

My action looks like this:

Name: Auto discovery. Windows servers.

Event Source: Discovery

Status: Enabled

Type of calculation: (A) and (B) and (C)

Action Operations: Add to group "Windows servers"
Link to template "Template_Windows"

But the machine is not shown in e.g. latest data? I must be missing something but I don't know what it is?

Can someone please shed light on this?

Checks: Zabbix agent
Status: active

And what item do you check against the Zabbix agent to see it's responding ?

(you can check system.hostname for instance...)

Usually, it works this way :

- setup an auto-discovery action that checks an item against a potential Zabbix agent (listenning on whatever is the port you specified)

- setup an action with the source event set on 'discovery' (and not triggers !), a match calculation based on 'source == Zabbix agent' (as far as I can remember), and the effective action set to add the host found to a logical group.

If you're not getting any hosts added, verify :
- the subnet you're scanning
- your action conditions and source event
- your action steps

Hi,

thanks for pointing this out. I just didn't see that i have to choose an item of the zabbix agent to check against.

Now I'm checking against "system.uname". Hopefully the actions are now working. I will have a look at the dashboard to see if the hosts are now discovered.

Thanks and Regards,

Now it works. Thanks a lot.
