Performing a Fault Drill of Increasing the CPU Usage

Scenarios

COC is a secure and efficient O&M platform, offering one-stop, AI-powered solutions for all your centralized O&M needs. You can configure drill templates and attack templates to perform fault drills on physical machines, VMs, or CCE containers in the chaos drill function module. You can also manage failure modes. You can select a target instance to execute fault drills.

This section describes how to use COC to perform a fault drill on an ECS to increase the CPU usage.

Operation Process

Preparations

1. Sign up for a HUAWEI ID and complete real-name authentication.

   Before using COC, sign up for a HUAWEI ID, enable Huawei Cloud services, and complete real-name authentication.

   If you already have enabled Huawei Cloud services and completed real-name authentication, skip this step.

2. Enable COC.

   Upon your first login, enable COC first.

   If you have enabled COC, skip this step.

Step 1: Synchronize Resources.
