[yuvaraj951]

I am newbie to Grafana, I have installed Grafana and did all the instructions given in the read me file. I'm using Visual Code for go lang now I just want to debug the Grafana code so that I can understand the process.
Can any one suggest me what I have to do. I have heard of debugger called Delve. Can any one tell me how to use it because when I use Delve it doesn't connect grafana server.
how to start the grafana-server and how to debbugging the code .Please any one help me out!!! and i want to contribute some thing to grafana!!!

I Have followed following Links : https://github.com/grafana/grafana , https://github.com/derekparker/delve

I got it to work by editing .vscode/launch.json:

{

            "type": "go",
            "request": "launch",
            "mode": "auto",
            "program": "${workspaceFolder}/pkg/cmd/grafana-server/main.go",
            "env": {},
            "args": [
                "--homepath", "${workspaceFolder}",
                "--packaging", "dev"
            ]
        }
    ]
}
