Visualized experiment is an approach that displays instance deployment information and enables real-time observation of fault injection effects during the experiment process. It can be achieved by orchestrating an experiment on Cloud Architecture. This document describes the fundamental features of visualized experiments and the method to quickly initiate a visualized experiment.
New Features of Visualized Experiment
Compared with traditional experiments, visualized experiments primarily provide the following new features:
Adding instances: You can visually view instance distribution through Cloud Architecture and directly initiate fault experiments for instances under cloud resources on the cloud architecture page.
You can quickly select instances to initiate experiments. This reduces usage costs, precisely controls the blast radius, and enhances experiment security.
You can see information such as the Virtual Private Cloud (VPC) and Availability Zone (AZ) of each instance added to the experiment in the visualized instance deployment diagram. This helps you understand the overall distribution of the experiment objects.
Performing experiments: Action injection and status visualization are supported.
Through Cloud Architecture, you can observe the fault injection status of each cloud resource in real time, making the experiment process more controllable and the experiment effects more intuitive.
Creating a Visualized Experiment from Cloud Architecture
Step 1: Creating an Experiment
1. Log in to the Tencent Cloud Smart Advisor (TSA) console, choose Cloud Governance, select Governance Mode, and click CFG. (If no architecture diagram is available, please first create one in drawing mode)
2. Click Create Experiment to go to the experiment configuration page.
Note:
An experiment can be created in multiple ways:
Click a graphic element in Cloud Architecture and select an instance on the details page to quickly initiate an experiment.
By using the fault action library and template library, you can reuse fault actions and industry templates and configure instances to create an experiment.
Step 2: Configuring the Experiment
1. Enter the experiment name, experiment objective, personnel organization, and other basic information for the experiment.
2. Select a resource object, such as MySQL.
3. To add an instance for experiment, click Add via Architecture Diagram, select the MySQL graphic element on the architecture diagram, select the instance resources you want to experiment with on the details page, and add them to the instance list. (Alternatively, click Search and Add, select instances from the search results list, and add them to the instance list).
4. Click Add Action to configure an experiment action.
5. Set the execution method and guardrail policy, and add observability metrics in the Global Configuration section. After the configuration is complete, click Submit.
Step 3: Viewing Experiment Details
After the experiment task is created, click View Details or click the experiment name on the experiment list page to go to the experiment details panel.
Step 4: Executing the Experiment
1. Click Start Experiment to start the experiment process. Alternatively, select a specific action group, and click Execute in the action group to execute the selected experiment action.
2. After the experiment starts, the execution effect of the experiment can be visually observed through Cloud Architecture:
Graphic elements show different colors, indicating different execution statuses.
By using the pre-configured observability metrics, you can view the monitoring diagram of the experiment instances.
Step 5: Ending the Experiment
1. Click End Experiment to record the experiment conclusion.
2. After the experiment ends, click Generate Report to summarize and review the experiment conclusion.
