Please help i have a problem on Data Source Mysql
The error message hints that Grafana cannot reach a mysql instance running on localhost port 3306. Are you running Grafana locally or Hosted Grafana?
I would suggest you start with connecting using the MySQL Command-Line Tool. When you got that working, you can continue with the data source in Grafana.
i dont have run grafana-cli.exe
