Unfortunately we are not supporting alerting if you use template variables. You can only set up alerting, if your query is not using template variables.

this is possible to remove template variables also have data gathers that I can set alert ??? for example on below query:

avg by (node_name) ((max_over_time(node_memory_MemFree_bytes{node_name=~"$node_name"}[$interval]) or max_over_time(node_memory_MemFree_bytes{node_name=~"$node_name"}[5m])) * 100 /
(max_over_time(node_memory_MemTotal_bytes{node_name=~"$node_name"}[$interval]) or max_over_time(node_memory_MemTotal_bytes{node_name=~"$node_name"}[$interval])))

The alert queries are executed by the Grafana server and Grafana datasource backend plugins without web browsers. The reason is the alerts have to run even when people are sleeping.

On the other hand the template variables stay in the web browser only. They are not saved as a part of queries. Therefore the server can’t know the value of the template variables.
