Technical Documentation and API Q&A for Capacity Planning and Resource Scaling: HTTP Interfaces and External Systems

In FastGPT v4.17.0, the data integration logic for the capacity planning and resource scaling category follows a unified HTTP interface specification.

What data for this category looks like

In FastGPT v4.17.0, the data integration logic for the capacity planning and resource scaling category follows a unified HTTP interface specification. Data for this category typically comes from cloud bills, monitoring systems, business forecasting reports, and stress test results. Update cycles run weekly or monthly. Daily deliverables include capacity planning reports, scaling application forms, resource utilization reports, and budget calculation sheets. Core fields include resource specifications, utilization thresholds, peak forecast values, and budget amounts. Corresponding units are CPU cores, memory capacity, request QPS, and budget amounts. Document structures generally include four sections: current resource analysis, forecast data, scaling solutions, and budget details.

What constraints these characteristics impose on HTTP interfaces and external systems

Data sources include periodically pulled cloud bills and batch-queried monitoring data. Interfaces must support periodic pulling and multi-dimensional batch queries. They must adapt to format differences across data sources. Document-style API requests must pass standardized business fields. These fields must match the structure of scaling applications and budget calculation documents. APIs for this category directly link to production resource configurations, unlike performance testing and capacity evaluation. This means parameter validation requirements are more strict. When integrating with external cloud vendor systems, interfaces must adapt to different authentication and format requirements. This ensures the legality of resource operations. It prevents configuration errors that cause peak-hour outages or resource waste.

How to configure settings

Configuration ItemRecommended ApproachRationale
AuthorizationBearer ${access_key}, follow cloud vendor authentication rulesComplies with HTTP interface standard authentication formats, adapts to most cloud vendor resource management APIs
variables{"resource_spec": "8 cores 16GB", "predict_window": "30d"}Passes resource specifications and forecast cycles required for capacity planning, matches query dimensions for business forecast data
responseData{"include": ["cpu_util", "mem_util", "peak_load"]}Only returns core capacity planning monitoring fields, reduces interface transmission overhead, adapts to extraction needs for operation and maintenance reports
Request timeout configuration600 secondsAdapts to response delay ranges for cloud vendor APIs, prevents capacity data pulling from being interrupted by timeouts
Resource parameter validation switchEnabledIntercepts scaling parameters that do not meet cloud vendor restrictions in advance, reduces the probability of configuration errors

Three common mistakes

  • Mixing Authorization parameters from local test and production environments when calling cloud vendor resource APIs. This triggers a 401 Unauthorized error. The cause is failure to distinguish authentication credential configurations for different environments.
  • Failing to properly encapsulate the variables parameter when submitting scaling applications via API. This causes the interface to return an empty field error. The cause is failure to pass resource type and application quantity information in the required document format.
  • Failing to specify filtering rules for responseData when pulling resource utilization data. This returns redundant non-core fields, reduces the efficiency of operation and maintenance report extraction. The cause is failure to match field requirements for capacity planning documents.

How to confirm configuration is complete

  • Call the test interface, check if the Authorization parameter is correctly parsed, and confirm that an expected authentication response is returned.
  • View the responseData field in the interface response, confirm that only preset core capacity planning fields are included, with no redundant content.
  • Submit a simulated scaling application, check if the variables parameter is correctly passed to the backend processing flow, with no parameter loss.
  • Compare resource data returned by the interface with values from local monitoring reports, confirm that data matching meets the calibration threshold for actual business needs.
