# Contributing
The Scrutiny repository is a [monorepo](https://en.wikipedia.org/wiki/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](https://go.dev/doc/install) (v1.20+)
2. download the `scrutiny-web-frontend.tar.gz` for
the [latest release](https://github.com/AnalogJ/scrutiny/releases/latest). Extract to a folder named `dist`
3. create a `scrutiny.yaml` config file
```yaml
# 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.
```bash
docker run -p 8086:8086 --rm influxdb:2.2
```
5. start the scrutiny web server
```bash
go mod vendor
go run webapp/backend/cmd/scrutiny/scrutiny.go start --config ./scrutiny.yaml
```
6. open your browser to [http://localhost:8080/web](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](https://nodejs.org/en/download/)
2. start the Angular Frontend Application
```bash
cd webapp/frontend
npm install
npm run start -- --serve-path="/web/" --port 4200
```
3. open your browser and visit [http://localhost:4200/web](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](https://go.dev/doc/install) (v1.20+)
2. install [NodeJS](https://nodejs.org/en/download/)
3. create a `scrutiny.yaml` config file
```yaml
# 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.
```bash
docker run -p 8086:8086 --rm influxdb:2.2
```
5. build the Angular Frontend Application
```bash
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
```bash
go mod vendor
go run webapp/backend/cmd/scrutiny/scrutiny.go start --config ./scrutiny.yaml
```
7. open your browser to [http://localhost:8080/web](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
```
