Performance Harness

Modules:

builder

A simple approach to generating environments. Entry point is init.sh. Takes in a few parameters and tries to setup an enviromnemnts using assembly jars.

templater/templater

A tool that is used by builder to generate configs.

templater/runner

Gatling based rnode client. Classes of note:

• ContinuousRunner
• DeployProposeSimulation

Automation

drone

Configuration and tools for a CI/CD tool that is used to setup an rchain network.

How to setup?

TBD

etc

Holds scripts that are used by drone to scrape results from runner.

hubot

Configuration for a bot attached to discord. A hubot test performance of master using contract contracts/dupe.rho will invoke a test using master image and contracts/dupe.rho contract.

tools

Holds a small set of tools that help build a perf runner docker image. To get a current version:

• setup.sh $$version$$

will result in an rchain-perf-runner:$$version$$ docker image.

This image can be then transported with docker save and docker load commands.

Metrics

prometheus & grafana

Configuration for docker-compose The usual docker-compose up should suffice to get monitoring.

Performance testing

setup

Assumption: an environment that has the boot-p2p script running:

• ./scripts/boot-p2p.py -b -p 3 -c 2 -m 2048m -i rchain/rnode:dev
• docker run -d -v /root/perf-runner/test-contracts:/contracts -e "loops=1" -e "sessions=3" -e "ratio=1" -e "hosts=peer1.rchain.coop" --name perf-runner --network rchain.coop rchain-perf-runner:0.1.0

rchain-perf-runner:0.1.0

This is the image that was built using Automation/tools script

perf-runner parameters

• -v /root/perf-runner/test-contracts:/contracts directory with contracts to run
• loops times to repeat the above directory
• sessions amount of concurrent clients
• ratio deploy : propose ratio
• hosts space separated list of hosts to test (assumed port is 40401)
