HSA homework 1

How to start

1. Clone the repo to local machine
2. Head to ./server on local machine and run npm install (required once to create node_modules folder before it will be projected to inner docker container filesystem)
3. Head to root of the cloned repo
4. Run docker-compose up -d
5. Enter into the console of the hsa_12_server container
   1. run npx typeorm-ts-node-commonjs migration:run -d ./src/database/config/ormconfig.ts
6. Go to localhost:4444
   1. configure datasource to influx
   2. import dashboard from https://grafana.com/grafana/dashboards/8709-tig-metrics/
7. Install siege (via homebrew/apt get etc)
8. Modify siege config to use custom urls file OR edit default file to contents of ./siege/siege-test.txt
9. In host machine console run siege - this will initiate siege script to process urls given in file mentioned above
10. Go to localhost:4444 and observe metrics changes

Alt testing

If siege is not your to-go option just configure your tool of choice to bombard POST http://localhost:5678/api/v1/unit-1/random with requests. This endpoint creates dummy entity with random generated id (UUIDv4) and store it to postgres, mongo and make an index of created model in elasticsearch/

Proofs

1. CPU / RAM / SWAP
2. Disk
3. Nginx
4. Mongo
5. Postgres
6. Elastic
