What data looks like for this category
Core data for log platforms and observability comes from log systems, Trace platforms, Metrics systems, and application SDKs, with an update frequency of daily or per version iteration. Daily produced documents include log collection specifications, link tracing instructions, indicator dictionaries, and dashboard configuration records. Data fields cover log levels, TraceID, indicator dimensions, collection timestamps, and more. Common units are bytes, milliseconds, entries, etc. The length of a single log record typically falls within the hundreds of characters range.
What constraints do these characteristics impose on forms and interactions
Access to multiple data sources requires external business systems to implement cross-system field association selection logic, to prevent incorrect collection field mapping. Frequently updated documents require external business systems to add version switching interactions, to adapt to specifications with different iteration cycles. Structural differences between multiple document types require external business systems to display forms in sections by collection, link tracing, and indicator management, to reduce filling complexity. Data association errors will directly lead to delayed fault location or missing audit trails. Real-time verification mechanisms must be implemented by external business systems or subsequent nodes to ensure field integrity and accuracy.
How to set configurations
The following configurations are adapted for FastGPT v4.17.0.
| Configuration Item | Recommended Practice | Rationale |
|---|---|---|
Form input node formInput | Test example: Select 3 fields from log platform and observability fields as required inputs; actual fields are determined by the task | This node collects user input. When required items are missing, interaction status must be checked to avoid subsequent nodes failing to obtain complete input |
User selection node userSelect | Test example: Set 2 business options, check corresponding branches one by one | This node handles user selection. Queries and filtering of log platform and observability related records must be implemented by subsequent interfaces or external systems |
| Field passing after submission | Test example: Prepare 10 log platform and observability input samples, covering complete filling, missing required items, and cancellation operations | Compare input and node output to verify whether subsequent nodes receive corresponding fields. Result thresholds are determined by actual tasks |
| External implementation item: Input length limit | Must be implemented separately by external systems; recommended value to be measured is 800–1200 characters | Matches the length range of single log records in test samples, configured by external business systems or subsequent nodes |
| External implementation item: Form section configuration | Must be implemented separately by external systems; divide into 3 modules: collection specifications, link tracing, and indicator management | Corresponds to the classification structure of daily documents |
| External implementation item: Default version selection | Must be implemented separately by external systems; the external business system specifies the currently active version, and the form node loads the corresponding configuration by default | Adapts to the daily or per version data update frequency |
Three common misconfigurations
- Symptom: The design document generated after form submission lacks the TraceID field. Verify: Check whether the
formInputnode is configured with input items for collecting TraceID fields, and confirm that the required items in the collection specification have been collected. - Symptom: Form submission times out after entering long log content. Verify: Check whether the form node is configured with input length limits, and confirm whether the external business system has synchronized the input verification logic.
- Symptom: The generated document matches the historical version collection specification. Verify: Check whether the external business system has adjusted the default version option according to the data update frequency, and confirm that the form node loads the currently active version configuration.
How to confirm configuration is complete
- Import a test log record containing TraceID and log level, check whether the
formInputnode collects the corresponding field content and passes it to subsequent nodes. - Switch different versions of collection specifications, confirm that the external business system synchronously updates the form display structure.
- Enter test content that exceeds the limit length, check whether the external business system triggers the corresponding input prompt, and confirm that the input verification logic of the
formInputnode takes effect. - Associate the external Trace platform node, confirm that the external business system can pull valid link information, and the
userSelectnode orformInputnode passes the information to subsequent nodes.
