Hi @rodrigoparavano,  
If you want to get label value from query then you can do with:

```auto
{{ $values.<queryname>.Labels.<tag> }}

```

For example:

```auto
On server {{ $values.B.Labels.host }} port {{ $values.B.Labels.port }} is closed (not listening).

```

would print:

```auto
On server monitoringserver port 8282 is closed (not listening).

```

**Bonus:**

> **Dynamic Severity labels**

> You can also do more advanced stuff like dynamic label value setting based on query values. For example you can set custom label Severity which would have next values:
> 
> > Fatal for values \>= 98  
> > Critical for values \>= 95 AND \< 98  
> > Warning for values \>= 90 AND \< 95  
> > NoData if $value.B does not exist
> 
> Severity label formula:
> 
> ```auto
> {{ if $values.result }}{{ if (ge $values.result.Value 98.0) }}Fatal{{ else if and (lt $values.result.Value 98.0) (ge $values.result.Value 90.0) }}Critical{{ else if and (lt $values.result.Value 90.0) (ge $values.result.Value 85.0) }}Warning{{ else }}None{{ end }}{{ else }}NoData{{ end }}

> Note that here my query in grafana alert is called result. Be aware that every time new severity label is created (for example Severity=Critical) a new alert check will be created and the alert with old Severity label (e.g. Severity=Warning) will be resolved with `"grafana_state_reason": "MissingSeries"`. Newly created check would first go to pending (if you set it) and then to alerting state.
> 
> In order to avoid quick changes of Severity label (and thus avoiding alerts being in pending mode) I usually use mean function in my query with time range of 5 minutes (mean of values over larger time range provides more stable number but it is slower at alerting). Also, I always first round numbers (with Math expression) and then perform Threshold expression over rounded numbers. Reason behind is also to avoid fast label changing.

> {{ if $values.result }}........{{ else }}NoData{{ end }}

> This is used so that when data is missing (e.g. agent has crashed or somebody stopped it) you get Severity=NoData instead of broken formula like on next picture:

Hope this helps. 🙂
