A a load generator for Salt

evil-minions

evil-minions is a load generator for Salt Open. It is being developed at SUSE to aid SUSE Manager scalability testing.

Status

Ongoing development, minimal functionality is there.

Installation

• install salt-minion 2015.8.12
• clone this git repository

Ideas and Usage

This project contains a script, dumping-salt-minion, that runs salt-minion while dumping all ZeroMQ traffic into a /tmp/minion-dump.yml file.

./dumping-salt-minion
# will create /tmp/minion-dump.yml

This "dump" can be fed to the evil-minions script, which will mimic the original minion by sending the same responses to equivalent requests coming from the master. It will by default simulate 10 copies of the original minions, the count can be changed via a commandline switch:

./evil-minions --count 5 <MASTER_FQDN>

Known limitations

• only the ZeroMQ transport is supported
• mine events are not really reproduced
• delays between responses are not reproduced
• state.sls's concurrent option does not really work
• only * and exact minion id targeting are supported at the moment
