Technical Documentation and Interface Q&A for Performance Testing and Capacity Assessment: HTTP Interfaces and External Systems

Data for this category primarily comes from pressure testing platforms, APM monitoring tools, database slow logs, and production traffic baselines.

What data for this category looks like

Data for this category primarily comes from pressure testing platforms, APM monitoring tools, database slow logs, and production traffic baselines. Documentation formats include pressure testing plans, capacity assessment reports, pressure testing data records, and optimization suggestion sheets. Update frequency is monthly or when major versions are released. Data fields include concurrent connections, request latency, resource usage, and throughput. Corresponding units are threads, milliseconds, GB, and requests per minute. No fixed percentage-based statistical metrics are included. A single set of documents covers the full performance testing workflow for one project, including test assumptions, execution scripts, indicator logs, and conclusion recommendations. This documentation applies to FastGPT v4.17.0.

The diversity of data sources requires HTTP interfaces to support integration with export interfaces from multiple external tools, to batch retrieve pressure testing and monitoring data. The periodic update frequency means interface call caching cycles must match monthly or version-level update rhythms, to avoid retrieving outdated data. The structured nature of documentation requires interface requests to support passing identification fields such as plan numbers and report IDs, to accurately associate test configurations for corresponding projects. The clear definition of fields and units requires request bodies and return values of interfaces to strictly match preset units and field names, to avoid indicator distortion caused by parameter mixing. Additionally, the most time-consuming links of this category—pressure testing model design and bottleneck identification—require interfaces to support batch retrieval of historical test data, to reduce the workload of repeated data entry.

How to set configurations

Configuration ItemRecommended SettingRationale
Concurrent Connection Upper Limit800–1200 threadsMatches the fluctuation range of production traffic baselines, covers peak scenarios
Request Timeout300 secondsAdapts to the longest request latency threshold recorded in pressure testing data logs
AuthorizationUse fixed tokens issued by the platformEnsures interface call security, complies with enterprise-level authentication specifications
variablesBind concurrent count and test address variables from pressure testing plansAdapts to pressure testing configurations for different versions, reduces manual modification workload
responseDataMap to throughput, latency, and resource usage fieldsMatches the standard field structure of capacity assessment reports
Data Pull CycleEvery 7 daysMatches monthly update frequency, avoids excessive external interface calls

Three Common Mistakes

  • Symptom: After calling the file upload recognition interface, XLSX files do not trigger AI conversations. Cause: The parsed text fields from files are not correctly mapped in responseData, causing subsequent conversation flows to fail to obtain valid input content.
  • Symptom: Workflows that loop calls to HTTP interfaces become unresponsive or interrupt. Cause: Request timeout values matching pressure testing scenarios are not set, causing single calls to be forcibly terminated after exceeding preset time thresholds.
  • Symptom: Garbled text appears when uploading text strings via the web interface, uploading text files, or uploading strings via the API. Cause: UTF-8 character encoding is not specified in request headers, causing character conversion errors during interface text parsing.

How to Confirm Configurations Are Correct

  • Call the Authorization authentication interface. A valid verification result indicates authentication configurations are correct.
  • Send a single test request. Check if fields returned in responseData match preset indicator fields from pressure testing plans.
  • Run a loop call test. Confirm that parameters bound to variables update automatically as the loop progresses.
  • Upload test text files and strings. Check that returned results and parsed content have no garbled text, confirming character encoding configurations meet requirements.
