Zabbix Trigger Dependency Question

[FrancisET]

Hi,

I'd like to get a better understanding of how trigger dependencies work, as it doesn't seem to work as to how I understand it. I'm using Zabbix 4.2 and have the default Linux template applied to CentOS7 hosts.

From this: https://www.zabbix.com/documentation...s/dependencies

"With dependency set notifications of the dependants could be withheld and only the notification for the root problem sent."

Applying this, my scenario is that I want to suppress notifications for Free swap space availability Less than 50% unless the "Lack of available memory on server" trigger is in the problem state. From my understanding, setting as dependency for the swap space trigger the Lack of available memory trigger will do this. It's not though, as notifications are still sent for the swap space trigger even though there's a lot of memory available.

Any guidance on how to do this properly will be greatly appreciated.

Kind regards,
Francis

it works exactly as described in docu, if you dont want notfication disable notification for lower severity and fire just the one you care for ( memory issue ) - whats ment by dependency is that the problem that are in lower level are being supressed by the time event at higher level is generated - taht way you dont have 1000 zabbix agent unreachable events in your dashboard ( high severity ) but just one with disaster ( zabbix proxy not running )

if there is a 1001 zabbix agent unreachable event opened while the zabbix proxy is still down the event will not generate its action

Hi gofree,

Thanks for chiming in. Well that's a bummer. I was expecting it to suppress notifications for a trigger which is dependent on another trigger in the problem state no matter what time.

Kind regards,
Francis
