Use Variable in Alert Notficiation Message

I am using grafana for alerting my six nodes when they are down.

Since alerting doesn’t support template variables, I have created six different queries in the metrics section which is:

cassandra1

Also, I have created an Alert.

While configuring the alert notification message, I have to write the message dynamically such as if node 1 is down, the message will be: Node1(value is taken from a variable) is down.

imgonline-com-ua-twotoone-WzYMtH2mXNa

How can I do it in an alert notification message?

is there any answer to this question?
