Performance pack

This pack contains actions for testing st2 performance

Actions

• delay - delay x seconds
• chain_delay_10 - delay x seconds 10 times in an action chain
• chain_delay_20 - delay x seconds 20 times in an action chain
• mistral_delay_10 - delay x seconds 10 times in a simple Mistral workflow chain
• mistral_delay - delay x seconds, y times, with z concurrency with Mistral
• mistral_parallel_delay - delay x seconds, y times, with full concurrency with Mistral
• mistral_list_delay - delay x seconds, y times, with full concurrency with Mistral in a manner most like Connect workflows

Policies

• delay20 - limit concurrency to 1 (not currently used)

Rules

• start_* - rules to start actions based on sensor triggers

Sensor

• watches .../packs/performance directory for run_* files
• run_xyz files contains json parameters, where "mode" is one of chain, repeat, or list (e.g. {"seconds":1.0,"iterations":20,"concurrency":1,"mode":"list"})
• run_xyz.ok is a semaphore file, informing sensor to read and process json file
• run_delay, run_chain, and run_mistral are currently supported

Setup

If running standalone (i.e. on native StackStorm and not as part of Composable Fabric Manager):

cd /opt/stackstorm/packs

git clone git@github.com:bri365/st2perf.git

Setup the pack virtualenv

st2 run

Usage

• manual testing st2 run performance.chain_delay_20 seconds=0.1
• sensor/trigger/rule based testing ./chain-loop, ./mistral-loop, or mistral-delay-test
