grafana Documentation

Some Fossies usage hints in advance:

  1. To see the Doxygen generated documentation please click on one of the items in the steelblue colored "quick index" bar above or use the side panel at the left which displays a hierarchical tree-like index structure and is adjustable in width.
  2. If you want to search for something by keyword rather than browse for it you can use the client side search facility (using Javascript and DHTML) that provides live searching, i.e. the search results are presented and adapted as you type in the Search input field at the top right.
  3. Doxygen doesn't incorporate all member files but just a definable subset (basically the main project source code files that are written in a supported language). So to search and browse all member files you may visit the Fossies
  4. grafana-6.4.4.tar.gz contents page and use the Fossies standard member browsing features (also with source code highlighting and additionally with optional code folding).

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.


  • Go (Latest Stable)
  • 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
cd $GOPATH/src/

Run and rebuild on source change


To run the backend and rebuild on source change:

make run


Install front-end dependencies first:

yarn install --pure-lockfile

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).


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

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.


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


Execute all frontend tests:

yarn test

Write and watch frontend tests:

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


# Run Golang tests using sqlite3 as database (default)
go test ./pkg/...
Running the MySQL or Postgres backend tests:

Run these by setting GRAFANA_TEST_DB in your environment.

  • GRAFANA_TEST_DB=mysql to test MySQL
  • GRAFANA_TEST_DB=postgres to test Postgres

Follow the instructions in ./devenv to spin up test containers running the appropriate databases with docker-compose

  • Use docker/blocks/mysql_tests or docker/blocks/postgres_tests as appropriate.
# Tests can only be ran in one Go package at a time due to clashing db queries. To run MySQL tests for the "pkg/services/sqlstore" package, run:
GRAFANA_TEST_DB=mysql go test ./pkg/services/sqlstore/...

# Or run all the packages using the circle CI scripts. This method will be slower as the scripts will run all the tests, including the integration tests.
# Postgres
# Tests can only be ran in one Go package at a time due to clashing db queries. To run Postgres tests for the "pkg/services/sqlstore" package, run:
GRAFANA_TEST_DB=postgres go test ./pkg/services/sqlstore/...

# Or run all the packages using the circle CI scripts. This method will be slower as the scripts will run all the tests, including the integration tests.


Execute all end-to-end tests:

yarn e2e-tests

Execute all end-to-end tests using using a specific url:

ENV BASE_URL=http://localhost:3333 yarn e2e-tests

Debugging all end-to-end tests (BROWSER=1 starts the browser and SLOWMO=1 delays each puppeteer operation by 100ms):

ENV BROWSER=1 SLOWMO=1 yarn e2e-tests

Datasource and dashboard provisioning

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