Installation

Head to docs.grafana.org and download the latest release.

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 1.9
  • NodeJS LTS

Building the backend

go get github.com/grafana/grafana
cd ~/go/src/github.com/grafana/grafana
go run build.go setup
go run build.go build

Building frontend assets

For this you need nodejs (v.6+).

npm install -g yarn
yarn install --pure-lockfile
npm run build

To rebuild frontend assets (typescript, sass etc) as you change them start the watcher via.

npm run watch

Run tests

npm run test

Run tests in watch mode

npm run watch-test

Recompile backend on source change

To rebuild on source change.

go get github.com/Unknwon/bra
bra run

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. custom.ini

In your custom.ini uncomment (remove the leading ;) sign. And set app_mode = development.

Running tests

  • You can run backend Golang tests using "go test ./pkg/...".
  • Execute all frontend tests with "npm run test"

Writing & watching frontend tests (we have two test runners)

  • jest for all new tests that do not require browser context (React+more)
    • Start watcher: npm run jest
    • Jest will run all test files that end with the name ".jest.ts"
  • karma + mocha is used for testing angularjs components. We do want to migrate these test to jest over time (if possible).
    • Start watcher: npm run karma
    • Karma+Mocha runs all files that end with the name "_specs.ts".

Contribute
