Hi,
I am new to Grafana so pardon me for novice issues. 
I am facing an issue when setting up an alerting for elasticsearch in grafana. When I go and edit my panel to setup an alert, I get “The datasource doesn’t support alert queries”. I am using elasticsearch to pull the data and as I understand, Grafana does support alerts on ES queries.
I am using Grafana 6.4.3:
Is there any step that I am missing? Which part should I look into to resolve this issue?
Thanks
