If you have any problems please read the troubleshooting guide.

Documentation & Support

Be sure to read the getting started guide and the other feature guides.

Run from master

If you want to build a package yourself, or contribute. Here is a guide for how to do that. You can always find the latest master builds here

Dependencies

• Go 1.5
• NodeJS v4+
• Godep

Get Code

go get github.com/grafana/grafana

Since imports of dependencies use the absolute path github.com/grafana/grafana within the $GOPATH, you will need to put your version of the code in $GOPATH/src/github.com/grafana/grafana to be able to develop and build grafana on a cloned repository. To do so, you can clone your forked repository directly to $GOPATH/src/github.com/grafana or you can create a symbolic link from your version of the code to $GOPATH/src/github.com/grafana/grafana. The last options makes it possible to change easily the grafana repository you want to build.

go get github.com/*your_account*/grafana
mkdir $GOPATH/src/github.com/grafana
ln -s  github.com/*your_account*/grafana $GOPATH/src/github.com/grafana/grafana

Building the backend

cd $GOPATH/src/github.com/grafana/grafana
go run build.go setup            (only needed once to install godep)
godep restore                    (will pull down all golang lib dependencies in your current GOPATH)
go run build.go build

Building frontend assets

To build less to css for the frontend you will need a recent version of of node (v4+), npm (v2.5.0) and grunt (v0.4.5). Run the following:

npm install
npm run build

To build the frontend assets only on changes:

sudo npm install -g grunt-cli # to do only once to install grunt command line interface
grunt watch

Recompile backend on source change

To rebuild on source change (requires that you executed godep restore)

go get github.com/Unknwon/bra
bra run

Running

./bin/grafana-server

Open grafana in your browser (default http://localhost:3000) and login with admin user (default user/pass = admin/admin).

Dev config

Create a custom.ini in the conf directory to override default configuration options. You only need to add the options you want to override. Config files are applied in the order of:

1. grafana.ini
2. dev.ini (if found)
3. custom.ini
