Hello Team
Im trying to define a segment in order to group all entities based on the tagName called app
the app tagname includes the application name, please see screenshot below
as you can see when I click on preview the result is always 0,
is there anyway we can achieve that ? or this should be done in different way ?
bestregards,
Makrem
Hi Makrem,
1. For Classic Entities
For classic entities, you can use the following approach to extract and filter tags:
Variable:
fetch dt.entity.host
| expand tags
| fields tags
| dedup tags Filter:
tags = "$tags" 
2. For Grail-based Data (Logs, Metrics, and Events)
When tags are applied directly to a server (e.g., using oneagentctl), they appear on the entity in the format [Environment]Owner:<Value>.
In Grail-based data, this tag is automatically ingested as a dedicated attribute named "Owner". This allows you to apply a direct filter within your segment as follows:
Owner = "$owner"
Note:
Please note that the two methods above do not work properly for Grail-based entities. This is because Grail-based entities have a different data structure for tag values compared to classic entities and record-level data (logs/metrics).
I'm still figuring out how to apply the segment using tags to grail-based entities.
Regards,
Firman
