CF application to bench external services

Summary

CF application to run bench scenarios on external services. Each service provides 2 scenarios, nominal & benchmark.

Nominal scenarios will launch a light test in order to check that your service works properly.

Benchmark scenarios will launch a heavy test to benchmark your service.

Currently supported services :

• mysql using sysbench as a benchmark tool
• redis using redis-benchmark as a benchmark tool

Currently implemented scenarios :

• mysql : nominal
• redis : nominal

⚠️ Please be advised that benchmarks need their own database, don't use a production database, it will result in dataloss. ⚠️

Installation

pre-requisites

• This application first needs a redis service in order to store result and queue awaiting benchmarks. This service name MUST starts with benchmark-redis-storage

  cf create-service redis plan benchmark-redis-storage

• Other services you will bind your application to will be benched, be careful as bench may resul in data loss

• You need to have pip3 installed to download vendor packages

• You need to be logged in your org/space and ready to cf push

configuration

• Open deploy_on_cf.sh
• Fill APP_REDIS_STORAGE with redis service you previously created
• Fill APP_SERVICES_TO_BENCH variable with services you wish to bench. If you want to bench multiple services, separate them with a space
• run ./deploy_on_cf.sh
• Optionnal : setting DONT_USE_REDIS_BENCHMARK will use a redis-benchmark substitute to avoid firewall issues

Usage

API exposes 2 routes :

• /run : will add an entry in redis queue to start benchmarks.
• /results : returns JSON object containing benchmarks results
• /metrics (to be implemented) : returns results in prometheus format

Just curl api_url/run to start benchmarks, results will appear on api_url/results as soon as they are available.

If you run a new bench, it will create new results, and so on.

API uses Flask & Celery to provide API and queuing
