Grafana

Grafana is an open source, feature rich metrics dashboard and graph editor for Graphite, Elasticsearch, OpenTSDB, Prometheus and InfluxDB.

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 (Latest Stable)
    • bra [go get github.com/Unknwon/bra]
  • Node.js LTS
    • yarn [npm install -g yarn]

Get the project

The project located in the go-path will be your working directory.

go get github.com/grafana/grafana
cd $GOPATH/src/github.com/grafana/grafana

Building

The backend

go run build.go setup
go run build.go build

Frontend assets

For this you need Node.js (LTS version).

yarn install --pure-lockfile

Run and rebuild on source change

Backend

To run the backend and rebuild on source change:

$GOPATH/bin/bra run

Frontend

Rebuild on file change, and serve them by Grafana's webserver (http://localhost:3000):

yarn start

Build the assets, rebuild on file change with Hot Module Replacement (HMR), and serve them by webpack-dev-server (http://localhost:3333):

yarn start:hot
# OR set a theme
env GRAFANA_THEME=light yarn start:hot

Note: HMR for Angular is not supported. If you edit files in the Angular part of the app, the whole page will reload.

Run tests and rebuild on source change:

yarn jest

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

Building a Docker image

There are two different ways to build a Grafana docker image. If your machine is setup for Grafana development and you run linux/amd64 you can build just the image. Otherwise, there is the option to build Grafana completely within Docker.

Run the image you have built using: docker run --rm -p 3000:3000 grafana/grafana:dev

Building on linux/amd64 (fast)

  1. Build the frontend go run build.go build-frontend
  2. Build the docker image make build-docker-dev

The resulting image will be tagged as grafana/grafana:dev

Building anywhere (slower)

Choose this option to build on platforms other than linux/amd64 and/or not have to setup the Grafana development environment.

  1. make build-docker-full or docker build -t grafana/grafana:dev .

The resulting image will be tagged as grafana/grafana:dev

Notice: If you are using Docker for MacOS, be sure to set the memory limit to be larger than 2 GiB (at docker -> Preferences -> Advanced), otherwise grunt build may fail.

Development

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

Frontend

Execute all frontend tests

yarn test

Writing & watching frontend tests

  • Start watcher: yarn jest
  • Jest will run all test files that end with the name ".test.ts"

Backend

# Run Golang tests using sqlite3 as database (default)
go test ./pkg/...

# Run Golang tests using mysql as database - convenient to use /docker/blocks/mysql_tests
GRAFANA_TEST_DB=mysql go test ./pkg/...

# Run Golang tests using postgres as database - convenient to use /docker/blocks/postgres_tests
GRAFANA_TEST_DB=postgres go test ./pkg/...
