Grafana is an open source, feature rich metrics dashboard and graph editor for Graphite, Elasticsearch, OpenTSDB, Prometheus and InfluxDB.
Head to docs.grafana.org for documentation or grafana.com/get to download the latest release.
Be sure to read the Getting Started guide and the other feature guides.
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
]
- yarn [
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
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 (https://localhost:3000):
yarn start
Build the assets, rebuild on file change with Hot Module Replacement (HMR), and serve them by webpack-dev-server (https://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. https://localhost:3000
) and login with admin user (default: user/pass = admin/admin
).
go run build.go setup
go run build.go build
For this you need Node.js (LTS version).
yarn install --pure-lockfile
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
- Build the frontend
go run build.go build-frontend
. - Build the docker image
make build-docker-dev
.
The resulting image will be tagged as grafana/grafana:dev
.
Choose this option to build on platforms other than linux/amd64 and/or not have to setup the Grafana development environment.
make build-docker-full
ordocker 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.
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:
- grafana.ini
- custom.ini
In your custom.ini uncomment (remove the leading ;
) sign. And set app_mode = development
.
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/...
Run these by setting GRAFANA_TEST_DB
in your environment.
GRAFANA_TEST_DB=mysql
to test MySQLGRAFANA_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
ordocker/blocks/postgres_tests
as appropriate.
# MySQL
# 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.
./scripts/circle-test-mysql.sh
# 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.
./scripts/circle-test-postgres.sh
Execute all end-to-end tests:
yarn e2e-tests
Execute all end-to-end tests using using a specific url:
ENV BASE_URL=https://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
Here you can find helpful scripts and docker-compose setup that will populate your dev environment for quicker testing and experimenting.
