Contributing

The Scrutiny repository is a monorepo containing source code for:

  • Scrutiny Backend Server (API)
  • Scrutiny Frontend Angular SPA
  • S.M.A.R.T Collector

Depending on the functionality you are adding, you may need to setup a development environment for 1 or more projects.

Modifying the Scrutiny Backend Server (API)

  1. install the Go runtime (v1.18+)
  2. download the scrutiny-web-frontend.tar.gz for the latest release. Extract to a folder named dist
  3. create a scrutiny.yaml config file
    # config file for local development. store as scrutiny.yaml
    version: 1
    
    web:
      listen:
        port: 8080
        host: 0.0.0.0
      database:
        # can also set absolute path here
        location: ./scrutiny.db
      src:
        frontend:
          path: ./dist
      influxdb:
        retention_policy: false
    
    log:
      file: 'web.log' #absolute or relative paths allowed, eg. web.log
      level: DEBUG
    
    
  4. start a InfluxDB docker container.
    docker run -p 8086:8086 --rm influxdb:2.2
    
  5. start the scrutiny web server
    go mod vendor
    go run webapp/backend/cmd/scrutiny/scrutiny.go start --config ./scrutiny.yaml
    
  6. open your browser to http://localhost:8080/web

Modifying the Scrutiny Frontend Angular SPA

The frontend is written in Angular. If you're working on the frontend and can use mocked data rather than a real backend, you can follow the instructions below:

  1. install NodeJS
  2. start the Angular Frontend Application
    cd webapp/frontend
    npm install
    npm run start -- --deploy-url="/web/" --base-href="/web/" --port 4200
    
  3. open your browser and visit http://localhost:4200/web

Modifying both Scrutiny Backend and Frontend Applications

If you're developing a feature that requires changes to the backend and the frontend, or a frontend feature that requires real data, you'll need to follow the steps below:

  1. install the Go runtime (v1.18+)
  2. install NodeJS
  3. create a scrutiny.yaml config file
    # config file for local development. store as scrutiny.yaml
    version: 1
    
    web:
      listen:
        port: 8080
        host: 0.0.0.0
      database:
        # can also set absolute path here
        location: ./scrutiny.db
      src:
        frontend:
          path: ./dist
      influxdb:
        retention_policy: false
    
    log:
      file: 'web.log' #absolute or relative paths allowed, eg. web.log
      level: DEBUG
    
    
  4. start a InfluxDB docker container.
    docker run -p 8086:8086 --rm influxdb:2.2
    
  5. build the Angular Frontend Application
    cd webapp/frontend
    npm install
    npm run build:prod -- --watch --output-path=../../dist
    # Note: if you do not add `--prod` flag, app will display mocked data for api calls.
    
  6. start the scrutiny web server
    go mod vendor
    go run webapp/backend/cmd/scrutiny/scrutiny.go start --config ./scrutiny.yaml
    
  7. open your browser to http://localhost:8080/web

If you'd like to populate the database with some test data, you can run the following commands:

NOTE: you may need to update the local_time key within the JSON file, any timestamps older than ~3 weeks will be automatically ignored (since the downsampling & retention policy takes effect at 2 weeks) This is done automatically by the webapp/backend/pkg/models/testdata/helper.go script

docker run -p 8086:8086 --rm influxdb:2.2

Modifying the Collector

brew install smartmontools
go run collector/cmd/collector-metrics/collector-metrics.go run --debug

Debugging

If you need more verbose logs for debugging, you can use the following environmental variables:

  • DEBUG=true - enables debug level logging on both the collector and webapp
  • COLLECTOR_DEBUG=true - enables debug level logging on the collector
  • SCRUTINY_DEBUG=true - enables debug level logging on the webapp

In addition, you can instruct scrutiny to write its logs to a file using the following environmental variables:

  • COLLECTOR_LOG_FILE=/tmp/collector.log - write the collector logs to a file
  • SCRUTINY_LOG_FILE=/tmp/web.log - write the webapp logs to a file

Finally, you can copy the files from the scrutiny container to your host using the following command(s)

docker cp scrutiny:/tmp/collector.log collector.log
docker cp scrutiny:/tmp/web.log web.log
