What data for this category looks like
This category’s data primarily originates from logging systems, distributed tracing (Trace) platforms, Metrics monitoring systems, and application SDKs. Daily maintained documentation includes logging collection specifications, tracing guides, metric dictionaries, and dashboard configuration records. Data update frequency is typically daily or aligned with application version iterations. Data fields include timestamps, request IDs, response status codes, business context identifiers, call chain durations, QPS, resource usage metrics, and more. Some fields require standardization based on business scenarios to ensure consistency across systems.
What constraints these characteristics impose on HTTP interfaces and external systems
Multi-source data access creates interface adaptation constraints, requiring support for authentication protocols and data formats from different systems. Frequently updated data requires interface response latency to match business rhythms, and overly long cache cycles should be avoided. The structured nature of documentation and configuration records requires interface parameters to cover configuration items such as field mapping and link association rules. Additionally, since data fields require standardization processing, interfaces must support passing standardization rule parameters to prevent subsequent fault location failures due to field mismatches. Fault location relies on complete data, so interfaces must ensure the integrity of returned data and must not arbitrarily truncate key business context fields.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
| Authentication parameters | Bearer {platform_api_key} | Used for authentication when connecting to external systems such as logging and tracing platforms, complies with access specifications of mainstream observability platforms, and can be directly filled in the interface configuration in FastGPT v4.17.0 |
| Context variables | { "standardizeFields": true, "timeRange": "last_24h" } | Used to pass standardization rules and time range parameters, adapts to the characteristics of this category's data requiring field standardization and periodic queries, and can associate business context across different systems |
| Number of returned data entries | Top 8-12 entries | Observability data typically contains a large number of redundant fields. Limiting the number of returned entries reduces interface transmission load while retaining key information required for fault location |
| Cache duration | 600 seconds | This category of data has a relatively high update frequency. Setting a cache duration of 600 seconds balances response speed and data freshness, and can be adjusted to the range of 300-900 seconds based on actual business scenarios |
| Field mapping switch | Enabled | This category of data requires standardization processing. Enabling field mapping converts raw fields from external systems into a unified format, facilitating subsequent analysis and fault location |
Three common misconfigurations
- Symptom: Incomplete logs or tracing data returned after calling the interface, with some key fields missing. Cause: The field mapping switch is not enabled, causing raw fields from external systems to not be converted to a unified format, resulting in filtering or failure to recognize.
- Symptom: Interface returns 401 Unauthorized error, or fails to obtain data from the target platform. Cause: Incorrect format of the authentication parameter, or failure to use a valid API key for the corresponding observability platform, resulting in authentication failure.
- Symptom: The AI response does not associate logs and tracing data, and cannot generate complete fault location information based on business context. Cause: Association parameters such as request ID are not configured in the context variables, causing the interface to fail to match logs and metric data for the corresponding link.
How to confirm the configuration is correct
- Call the configured HTTP interface, check whether the authentication parameter is correctly carried, and view the request details through the platform debugging tool.
- Check whether the returned data contains expected logs, tracing or metric fields, and confirm that the field mapping switch is active.
- Pass a test request ID parameter, verify whether the interface can return associated data for the corresponding link, and confirm that the context variable passing is active.
- Simulate expired data query, check whether the interface returns a data set matching the time range, and confirm that the time range parameter is active.
