Add field to filter by value on Grafana query

[rp2019433]

Description

It would be useful to add a field on Grafana query to filter data to be shown by its value.

I have some OSPF monitoring on Zabbix, like the figure below. I'd like to create dashboards, using Stat panel, to show how many adjacencies are in full state (using count function), it means I need to filter the data to be shown by its value. If the value is not "full (8)", then it's not counted on Grafana.

Possible solution

Add a field to filter data by its value as a query option.

Thank you!
