Actions and Probes
This page lists all the activities available for your chaos engineering experiments in Reliably. There are two main types of activities: actions and probes.
Whether you call them attacks or turbulences, actions are used to introduce specific conditions to your system, in order to observe how it behaves. Probes are used to retrieve information from your system, allowing you to compare its state before, during, and after the conditions induced by your actions.
