Contributing Guidelines

Welcome to SigNoz Contributing section 🎉

Thank you for your interest in contributing to our project. Whether it's a bug report, new feature, correction, or additional documentation, we greatly value feedback and contributions from our community.

Please read through this document before submitting any issues or pull requests to ensure we have all the necessary information to effectively respond to your bug report or contribution.

Sections:

1. General Instructions 📝

Before making any significant changes and before filing an issue, please check existing open, or recently closed, issues to make sure somebody else hasn't already reported the issue. Please try to include as much information as you can.

Details like these are incredibly useful:

  • Requirement - what kind of use case are you trying to solve?
  • Proposal - what do you suggest to solve the problem or improve the existing situation?
  • Any open questions to address

If you are reporting a bug, details like these are incredibly useful:

  • A reproducible test case or series of steps.
  • The version of our code being used.
  • Any modifications you've made relevant to the bug🐞.
  • Anything unusual about your environment or deployment.

Discussing your proposed changes ahead of time will make the contribution process smooth for everyone.

Once the approach is agreed upon, make your changes and open a Pull Request(s).

Note: Unless your change is small, please consider submitting different Pull Rrequest(s):

  • 1 First PR should include the overall structure of the new component:
    • Readme, configuration, interfaces or base classes, etc...
    • This PR is usually trivial to review, so the size limit does not apply to it.
  • 2 Second PR should include the concrete implementation of the component. If the size of this PR is larger than the recommended size, consider splitting it into multiple PRs.
  • If there are multiple sub-component then ideally each one should be implemented as a separate pull request.
  • Last PR should include changes to any user-facing documentation. And should include end-to-end tests if applicable. The component must be enabled only after sufficient testing, and there is enough confidence in the stability and quality of the component.

You can always reach out to ankit@signoz.io to understand more about the repo and product. We are very responsive over email and SLACK.

  • If you find any bugs → please create an issue.
  • If you find anything missing in documentation → you can create an issue with the label documentation.
  • If you want to build any new feature → please create an issue with the label enhancement.
  • If you want to discuss something about the product, start a new discussion.

Conventions to follow when submitting Commits and Pull Request(s).

  • We try to follow Conventional Commits. , more specifically the commits and PRs should have type specifiers prefixed in the name. This should give you a better idea.

e.g. If you are submitting a fix for an issue in frontend, the PR name should be prefixed with fix(FE):


2. How to Contribute 🙋🏻‍♂️

There are primarily 2 areas in which you can contribute to SigNoz

  • Frontend (Written in Typescript, React)
  • Backend (Query Service, written in Go)

Depending upon your area of expertise & interest, you can choose one or more to contribute. Below are detailed instructions to contribute in each area.

Please note: If you want to work on an issue, please ask the maintainers to assign the issue to you before starting work on it. This would help us understand who is working on an issue and prevent duplicate work. 🙏🏻

⚠️ If you just raise a PR, without the corresponding issue being assigned to you - it may not be accepted.


3. Develop Frontend 🌝

Need to update https://github.com/SigNoz/signoz/tree/main/frontend

3.1 Contribute to Frontend with Docker installation of SigNoz

  • git clone https://github.com/SigNoz/signoz.git && cd signoz

  • comment out frontend service section at deploy/docker/clickhouse-setup/docker-compose.yaml#L62

  • run cd deploy to move to deploy directory

  • Install signoz locally without the frontend

    • Add below configuration to query-service section at docker/clickhouse-setup/docker-compose.yaml#L38
    ports:
      - "8080:8080"
    
    • If you are using x86_64 processors (All Intel/AMD processors) run sudo docker-compose -f docker/clickhouse-setup/docker-compose.yaml up -d
    • If you are on arm64 processors (Apple M1 Macbooks) run sudo docker-compose -f docker/clickhouse-setup/docker-compose.arm.yaml up -d
  • cd ../frontend and change baseURL to http://localhost:8080 in file src/constants/env.ts

  • yarn install

  • yarn dev

Notes for Maintainers/Contributors who will change Line Numbers of Frontend & Query-Section. Please Update Line Numbers in ./scripts/commentLinesForSetup.sh

3.2 Contribute to Frontend without installing SigNoz backend

If you don't want to install the SigNoz backend just for doing frontend development, we can provide you with test environments that you can use as the backend. Please ping us in the #contributing channel in our slack community and we will DM you with <test environment URL>

  • git clone https://github.com/SigNoz/signoz.git && cd signoz/frontend
  • Create a file .env with FRONTEND_API_ENDPOINT=<test environment URL>
  • yarn install
  • yarn dev

Frontend should now be accessible at http://localhost:3301/application


4. Contribute to Backend (Query-Service) 🌕

Need to update: https://github.com/SigNoz/signoz/tree/main/pkg/query-service

  • Clone SigNoz,
git clone https://github.com/SigNoz/signoz.git
    expose:
      - 9000
    ports:
      - 9001:9000
  • run cd pkg/query-service/ to move to query-service directory,

  • Open ./constants/constants.go,

    • Replace const RELATIONAL_DATASOURCE_PATH = "/var/lib/signoz/signoz.db"
      with → const RELATIONAL_DATASOURCE_PATH = "./signoz.db".
  • Now, install SigNoz locally without the frontend and query-service,

    • If you are using x86_64 processors (All Intel/AMD processors) run sudo make run-x86
    • If you are on arm64 processors (Apple M1 Macs) run sudo make run-arm

Run locally

ClickHouseUrl=tcp://localhost:9001 STORAGE=clickhouse go run main.go

Notes for Maintainers/Contributors who will change Line Numbers of Frontend & Query-Section. Please Update Line Numbers in ./scripts/commentLinesForSetup.sh

Query Service should now be available at http://localhost:8080

If you want to see how the frontend plays with query service, you can run the frontend also in your local env with the baseURL changed to http://localhost:8080 in file src/constants/env.ts as the query-service is now running at port 8080



5. Contribute to SigNoz Helm Chart

Need to update https://github.com/SigNoz/charts.

5.1 To run helm chart for local development

  • run git clone https://github.com/SigNoz/charts.git followed by cd charts
  • it is recommended to use lightweight kubernetes (k8s) cluster for local development:
  • create a k8s cluster and make sure kubectl points to the locally created k8s cluster
  • run make dev-install to install SigNoz chart with my-release release name in platform namespace.
  • run kubectl -n platform port-forward svc/my-release-signoz-frontend 3301:3301 to make SigNoz UI available at localhost:3301

To install the HotROD sample app:

curl -sL https://github.com/SigNoz/signoz/raw/main/sample-apps/hotrod/hotrod-install.sh \
  | HELM_RELEASE=my-release SIGNOZ_NAMESPACE=platform bash

To load data with the HotROD sample app:

kubectl -n sample-application run strzal --image=djbingham/curl \
  --restart='OnFailure' -i --tty --rm --command -- curl -X POST -F \
  'locust_count=6' -F 'hatch_rate=2' http://locust-master:8089/swarm

To stop the load generation:

kubectl -n sample-application run strzal --image=djbingham/curl \
  --restart='OnFailure' -i --tty --rm --command -- curl \
  http://locust-master:8089/stop

To delete the HotROD sample app:

curl -sL https://github.com/SigNoz/signoz/raw/main/sample-apps/hotrod/hotrod-delete.sh \
  | HOTROD_NAMESPACE=sample-application bash

Again, feel free to ping us on #contributing or #contributing-frontend on our slack community if you need any help on this :)
