discovery notifications to avoid existing devices

[mohit.zabbix.d]

Hi Guys,

I am exploring Zabbix 7.0 LTS and loving it so far.

I am trying to create a Zabbix discovery with below details

Discovery Rule -

• discovery devices with ip range - 172.20.200.1-254
• checks - ICMP Ping
• criteria - IP address
• host and visible name - ip address or DNS name

Discovery Action -

• condition A - host ip equals - 172.20.200.1-254
• Operations 1 - Add host
• Operations 2 - add to host groups - discovered ip range 200
• operations 3 - send email to administrator on discovered devices.

Discovery works fine, but each time the rule runs administarator will get all the devices again and again in the newly discovered list.
i was trying to find a condition for discovery action, but not able to find one that can filter the existing devices besides making a condition to avoid host ip equals - 172.20.200.x, which is not enough for a whole subnet scan.
Has
anyone experienced something like this or i am not able to understand this flow properly, so missing something here?

Hi,
I believe your discovery action condition should be Discovery Rule = <whatever you called your rule> rather than a reiteration of IP = network as then it is independent of your discovery rule and acting of its own volition.
