A selection or dropdown menu for finding "existing" tags on a host/template items/triggers just like we have for Hostgroups would be extremely useful!

Now indeed, if you are not 100% consistent this is within 5 minutes a mess...

+1 for this idea!

I was actually discussing this in a training after I received a question about applications being removed and I can tell you that 5 trainees (and myself) here agree.

This feature missing from what we had with applications before is definitely a loss. Gotta have it back

be careful what you wish for ˆˆ

prometheus has labels (tags) something like this where you can choose the tags to filter would be. nice i t hink

it would even be more cool if we had a latest data page like this where you have the visual overview of the metrics that you can choose on the right

it should be possible to show all tags starting with name cpu under CPU so that we can select the correct value per tag.

In this case latest data would integrate latest data and graphs in some way

I guess that already exists with host dashboards. but you're right we need the application or something like that back

host dashboards are a step in the right direction but are not usable at the moment.

https://support.zabbix.com/browse/ZBXNEXT-6727

i made a ticket about it 

there is too much work to do at the moment if you like to make a dashboard that works for lets say 10 hosts 

you need to make 10 dashboards in zabbix and every widget needs to get configured manually

in grafana this is possible with 1 dashboard and some regex to filter 

We are aiming to fix usability issues related to removal of applications in 6.0, at least for Latest data view. I'd like to see simple interface for filtering, preferably with one-click selection of tags, not sure about grouping. I find grouping in Latest data (as it was in 5.2 and earlier versions) not perfect, perhaps flat table view (5.4) is a better choice.

I can assure you that nobody thinks that the current flat table view is usable. We need a way to group by tags as we used to do with applications, this is basic functionality that almost every other monitoring solutions has. Plz guys, just take a look at any feedback about 5.4. This is the 1# problem mention on every forum post and group chat.

There is also a plugin available that solves the issue Zabbix has ignored until today: https://github.com/BGmot/zabbix-module-latest-data

I think that grouping can be done in many ways. One solution is just to group items in the table as we did before and what the plugin does. Another solution (a better one, but I might be wrong) is to introduce one click selection of tags and tag values you want to filter information by. Perhaps a combination of both is the best one. I will try to come up with mockups later on.

First of all very happy to hear that the Tag filtering is being worked on, as it definitely very important to the overal perception of 6.0.

Related to ZBX-19413: When it comes to the flat view, I agree with Alexei that grouping can be done in many ways and options to make things better should always be explored once the chance arrives. 

Zabbix 6.0 isn't a very long way off though so just an idea for a possible quick fix. It would be possible to allow us to sort the latest data page by tags. Not possible at the moment, as we can only sort on name or host. Sorting by tags would basically allow us to use the latest data page like the old way of applications. Just without the option to collapse each tag.

Looking forward to the mockups

We could introduce a "tag cloud" thing.
