Remove Down Device from Discovery

[Linuxjohnny]

Hi

Maybe a simple question but for now i didn't find a way to do this

I'm monitoring all Swtich and Accesspoints Management Networks via Disovery Rules and add new hosts automaticly.
I also have a rule for remove hosts if they are down for a specific time.
But the Hosts will still appear in the Tab Monitoring -> Disovery "Status of discovery"

Here are some Screenshots:

Discovery Tab:

Remove Action:


If you need more information please ask
So this is my first post and i hope i didn't forget something...

Many thanks for your replys!

Hello and welcome to Zabbix forums!

I think it is the designed behavior. The host is still listed in "dhosts" and "dservices" tables in Zabbix database even after it is not discovered anymore. Otherwise how would you be able to execute that action on "Downtime".

I get your point, you want the host to be removed from the list once it is not discovered anymore and removed from configuration, correct? In that case it could be a new feature request.

Hi

Thanks for your reply!

Ok yes that can be a case. I think then there should be an option in the discovery actions to clear this tables...
Or something like the "Keep lost ressources period" option in the Disovery Rules...

And yes you're right, i just want to remove it

For now i just deleted the entries in dhosts and dservices:

DELETE FROM dhosts WHERE dhostid = 326;
DELETE FROM dservices WHERE dserviceid = 326;

Is that enough?

But if you know a better way to do this just let me know

I think it is good enough for now.

Cool! Thanks for your help!
ingus.vilnis Do you think its worth to create a feature request?

Hi,

Yes, why not. But since the existing functionality might be used by others already, I think you can request for something like a checkbox to remove hosts from the Monitoring -> Discovery list after they are not discovered for more than x time.
