Now that we’ve defined our experiment and gathered observations, let’s run the experiment. Start by opening the Gremlin tab in your browser. On the left navigation bar, click Attacks, followed by New Attack.
Under “What do you want to attack?”, select Infrastructure, then Hosts. You can either select each host individually, or click Target all hosts to select all three of your hosts.
Expand Choose a Gremlin and select Resource, then CPU. Change Length to
360, change CPU Capacity to
80 and select “All Cores” from the dropdown.
Now, click Unleash Gremlin to start the attack.
If you want to stop the attack at any time, click either the Halt or Halt All Attacks button in the top-right corner.
🎉 Congrats, you’ve unleashed your first attack! In the next page, we will talk about observing the chaos engineering experiment we just unleashed.
