Adding Data Source

Hi…I have an existing grafana dashboard installed in a windows server and it monitors the SQL server perfromance in the server.When i try to add a new dashboard i cant see any options to add datasource.Do i have to go to plugin and add Datasource every time i build a new dashboard.?

No, data sources only have to be created once. Could you show a screenshot of what you are trying to do? Are you new to Grafana and need some help creating a new dashboard or is this a potential bug?
