Website | Twitter | Community & Forum

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

Installation

Head to docs.grafana.org for documentation or download to get the latest release.

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 (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/...

Datasource and dashboard provisioning

Here you can find helpful scripts and docker-compose setup that will populate your dev environment for quicker testing end experimenting.
