Prevent item delete "The item is not discovered anymore and will be deleted"

[Oigres]

Hello.

Im new with zabbix and i have a question.

I use auto discovery and now i made some changes and some items are not discovered anymore.

I have a menssage in this items "The item is not discovered anymore and will be deleted", but i want to keep the data from this items to check the graphs.

Any way to prevent this?

Thank you.

Hello,

Maybe , Can you change the parameter " Keep lost resources period " in Discovery Rule, but I think not so good practices to storage data.

Thank you for your reply.

I just want to keep some items, not all of them.

The only alternative, (depending on the number discovered items / hosts) is to delete the unwanted items manually after increasing the "Keep lost resources period" value. Again, increasing the "Keep lost resource period" is not a good practice as Hernandes Martins already mentioned.

I was thinking on doing that.

Sorry if what I propose is stupid:
Wouldn't running the discoveries associated with the host again resolve the issue? Thank you for the availability and good predisposition

No..He was asking to keep items that are no longer discovered by LLD indefinitely. Running discovery again would just discover what is available - items created before(by LLD) will be deleted after time specified in "Keep lost resource period" in LLD.

In theory (haven't tested) you should be able to keep that item if you change the lastcheck field in the item_discovery table.

Find out the itemid of your item (e. g. go to Configuration section, select host, items, right-click your item and Inspect the HTML code, it will be in data-itemid attribute), then go to your database and execute:

update item_discovery set lastcheck=unix_timestamp('2038-01-01') where itemid=<ITEMID>;
