What the data for this category looks like
This category’s daily documents include four types: VPC planning, security group rules, load balancing configuration, and change tickets. Data is mainly derived from configuration snapshots exported from cloud platform consoles, network topology diagrams, real-time traffic monitoring data, and architecture design drawings submitted by customers. Updates are triggered by each configuration change or work order. The core fields of a single document include network segment range, listening port, health check interval, and backend server group list. Field units are mostly CIDR blocks, seconds, connection counts, and similar units.
What constraints these characteristics impose on the "forms and interactions" link
Since data sources are mostly structured console exports and visual topology diagrams, forms must support linkage with external batch import tools to receive structured configuration fragments. Due to the high frequency of change triggers and fixed fields per document, the core field input template for the form must be implemented by an external business system to avoid duplicate data entry. Fields such as network segments and ports have clear format and unit constraints. The interaction link must link with external format verification logic to prevent invalid parameters from entering subsequent processes. Numeric fields such as health check interval must match the standard value range of the cloud platform to avoid service exceptions after configuration.
How to set the configuration
The following configurations are developed based on the form input and user selection node capabilities of FastGPT v4.17.0, combined with external business system data. Nodes are only responsible for collecting and passing inputs, and specific configuration logic is implemented by external systems.
| Configuration Item | Recommended Approach | Basis for This Approach |
|---|---|---|
Form input node formInput | Test example: Select 3 fields from cloud networking and load balancing configuration as required inputs; actual fields are determined by the task | This node collects user input; when required items are missing, the interaction status must be checked to avoid subsequent nodes failing to obtain complete inputs |
User selection node userSelect | Test example: Set 2 business options, check corresponding branches one by one | This node handles user selection; querying and filtering records related to cloud networking and load balancing configuration must be implemented by subsequent interfaces or external systems |
| Post-submission field passing | Test example: Prepare 10 cloud networking and load balancing configuration input samples, covering complete filling, missing required items, and cancel operations | Compare inputs and node outputs to verify whether subsequent nodes receive corresponding fields; result thresholds are determined according to actual tasks |
| External implementation item: Health check interval | Must be implemented separately by the external system; 5–30 seconds | Complies with the standard health check response interval for cloud network load balancing, this is a test example value |
| External implementation item: Backend server group limit | Must be implemented separately by the external system; first 20 entries | Test example configuration scale for a single change ticket |
| External implementation item: Change ticket associated ID | Must be implemented separately by the external system; filled by extraction from the external system | Extract and pass data from work orders exported from the cloud platform console to avoid manual entry |
Three Common Mistakes
- Phenomenon: A 400 status code is returned after form submission, with the prompt "Invalid network segment format. Verification steps: Verify whether the external format verification logic is linked to the form, confirm whether non-CIDR format network segment inputs are blocked.
- Phenomenon: Traffic forwarding exception occurs after execution, and no traffic accesses backend servers. Verification steps: Verify whether the backend server group option list is generated from external cloud platform data, confirm that the list matches the server groups in the cloud platform console.
- Phenomenon: The change ticket is not linked to the original operation and maintenance work order after submission. Verification steps: Check whether the external system passes the associated ID to the form, confirm whether the submitted ID matches the work order data exported from the cloud platform console.
How to Confirm the Configuration Is Correctly Set
- Import a load balancing configuration fragment exported from the cloud platform console, check whether the external linkage tool transfers the fragment to the form and completes the corresponding field filling.
- Enter a network segment in non-CIDR format, check whether the externally linked format verification logic triggers a prompt.
- Select a backend server group option, confirm that the option list is generated from external cloud platform data and matches the server groups in the cloud platform console.
- Submit a test change ticket, check whether the external system passes the associated ID to the form and completes filling.
