Hello, Is it possible to configure an alert when the database is down? I get the alert triggered configuring ‘If execution error or timeout’ to Alerting but Grafana is not able to send the email. Error is Execution Error: tsdb.HandleRequest() response error &{dial tcp 127.0.0.1:5432: connect: connection refused.
Database is Postgresql, grafana config is stored in the database.
Hi! 
The error message is because Grafana cannot connect to the database. Is Postgres running and listening on localhost port 5432?
Hello, Postgresql is down intentionally as I want to report that condition.
The issue was finally that the customer mail sever was blocking my address, the email was being generated in grafana.
Thank you.
