    build: .
    environment:
      - COMPONENT_NAME=testserver

Cause surgery accidents!

• If you want to change any resource metric abnormally to test alert rules, for example, do

curl -X POST http://localhost:3000/surgery-accident
{
	"resource": "transaction-0100",
	"type": "latency",
	"value": "100"
}

• After this, transaction-0100 median latency will be ~100x the original

• 'resource' accepts regular expressions for matching N resource names (for example, 'transaction-.*')

• To remove all accidents, send a DELETE to the same endpoint

curl -X DELETE http://localhost:3000/surgery-accident
