To query metrics: Enconding:

• "'" => %27
• "," => %2C

1. curl "http://0.0.0.0:80/render?target=consolidateBy(webserver.get_todos.success%2C%27sum%27)&from=-1h&format=json"
2. curl "http://0.0.0.0:80/render?target=removeEmptySeries(webserver.get_todos.success%2C0.1)&from=-1h&format=json"
3. curl "http://0.0.0.0:80/render?target=consolidateBy(webserver.get_todos.success%2C%27sum%27)&from=-10min&format=json"
4. curl "http://0.0.0.0:80/render?target=maxSeries(webserver.get_todos.success)&from=-10min&format=json"
5. curl "http://0.0.0.0:80/render?target=removeBelowValue(webserver.get_todos.success%2C1)&from=-15min&format=json"
6. curl "http://0.0.0.0:80/render?target=removeBelowValue(transformNull(webserver.get_todos.success)%2C0)&from=-60min&format=json"
7. curl "http://0.0.0.0:80/render?target=removeBelowValue(transformNull(webserver.get_todos.success)%2C%200)&format=json"

To build it:

1. docker-compose build --no-cache

To run it:

1. docker-compose up -d

To stop it:

1. docker-compose down --remove-orphans

To run it:

1. go test -v -tags=integration ./...
2. go test ./tests -tags=integration

1. docker-compose up -d

2. docker ps => you should see the two containers up & running

3. go test ./tests -tags=integration
