Repository for my talk on performance testing

web-scale-perf-testing

• use Docker Compose to run all at once
• use InfluxDB + Grafana to collect metrics from Gatling
• use dc scale gatling=N to make more load for app
• added support of Vagrant

Fake service for Patient entity

In order to run fake service execute from project root directory:

  ./gradlew :patient-service:runShadow

In order to create a deployable jar file:

    ./gradlew :patient-service:shadowJar

Run everything

• Run all required parts

    ./gradlew :patient-service:runShadow
    dc up -d grafana

• Add datasource for InfluxDB

    curl -u admin:admin -X POST -H "Accept: application/json" -H "Content-Type: application/json" -H "Cache-Control: no-cache" -d '{
