Grafana v7.3.6 Alert Notification Message

Hi All,

I have Grafana v7.3.6 version and using it with Influxdb. I need assistance in sending alert message for each host sending metrics to the influxdb so please suggest how I can use the hostname variable in the grafana alerting message.
Below is the screenshot of the grafana template i have configured and notification i am receiving at the moment. In the notification i am not getting the actual hostname instead the variable as it is :frowning:
