Discovery Rule Not Discovering

[tomthetommy]

Hi All,

So I have a network 192.168.0.1-254, I have configured the Discovery rule as such:

IP Range: 192.168.0.1-254
Checks: system.uname
Device Uniqueness: Hostname

Action:

Conditions:
A Discovery check = Development 10.180: Zabbix agent "system.uname"
B Received value like Linux

Operations:

Link to template.


Now this never works. I never get hosts appear in the template. It will only work if I add a ping check in, and add that to the Actions conditions.
What is stopping Zabbix from going out and discovering the hosts?

The agent is all setup on the clients. I can use zabbix_get from Zabbix to the hosts to verify it can access the hosts data.

I have used netstat on the Zabbix machine as follows:

netstat -tnuap | grep "10050" to try and verify that it's going out and connecting to machines to pull the initial data for discovery. But there is nothing.

Any help is much appreciated.

What's your Zabbix version? Can it be this issue is hitting you?

I'm betting somewhere your setting is wrong or not enabled

Discovery rule name: Development 10.180
IP Range: 192.168.0.1-254
Delay (if 1 hour, check the result after 1 hour). or reduce it to 5 minutes see if it works really quick.
Checks: Zabbix agent "system.uname" -type is zabbix agent right?
Device Uniqueness: system.hostname

Looks like you don't have a check for Device hostname when you're using uniqueness of hostname.
Checks: Zabbix agent "system.hostname" <- this is needed too?


Discovery Action Condition:

Conditions:
A Discovery check = Development 10.180: Zabbix agent "system.uname"
B Received value like Linux (This seems right)
