What this category of data looks like

Data for this category originates from monitoring alerts, log platforms, APM tools, and user feedback. Update frequency is real-time or following each event trigger. Daily associated documents include fault tickets, event timelines, emergency response plans, and fault notifications. Data fields include unique fault identifiers, affected service scope, occurrence time, stop-loss operation records, notification recipients, with no additional custom units. Fields are dynamically supplemented as the event progresses.

Real-time updated data sources require limiting the range of historical messages in dialogue context to avoid redundant data interfering with current fault analysis. Diverse daily document structures require prompt engineering to adapt to input content in different formats, matching the field logic of fault tickets and event timelines respectively. Dynamically supplemented fields must be passed via variables to ensure prompt engineering can call the latest event information. Additionally, the high-risk nature of fault handling requires the dialogue link to verify input content legality, preventing invalid data from triggering exceptions.

How to configure the settings

The following configurations are compatible with FastGPT v4.17.0.

Configuration ItemRecommended ApproachRationale
chatIdBind to the unique event identifierEnsure isolation of dialogue context in the same scenario, avoiding cross-event data confusion
messagesRetain the most recent 20 dialogue recordsAdapt to the real-time requirements of fault handling, avoiding model overload caused by overly long context
variablesPass in fault ID and affected service fieldsMatch dynamically supplemented event data, allowing prompt engineering to call the latest business information
Maximum context length8000–12000 tokenBalance the completeness of fault data and model inference efficiency
Prompt templateSplice input content in the order of fault ticket → event timeline → current questionAdapt to the structured characteristics of documents in this category, improving analysis accuracy
Historical message truncation thresholdCalibrate based on actual testingAdapt to event data volumes of different scales, avoiding context overflow

Three common configuration errors

  • A 400 invalid image status code is returned when calling the multi-modal dialogue interface. The cause is failure to verify the format and size of input image files, which does not meet the model's input requirements.
  • The workflow runs normally when debugged within FastGPT, but only the first dialogue node executes after connecting to a third-party dialogue interface. The cause is failure to correctly pass the chatId parameter, preventing dialogue context from persisting across interfaces.
  • After configuring a locally deployed model, the model is automatically replaced with another type during dialogue. The cause is failure to lock the unique identifier of the target model in LLM configuration, causing the proxy service to automatically switch the model.

How to confirm the configuration is complete

  • Check whether chatId is bound to the unique identifier of the current event. Dialogue logs can be reviewed to confirm whether context is associated with the specified event.
  • Verify whether variables pass the core fields of fault tickets and event timelines. Variable mapping correctness can be checked via the debug interface.
  • Confirm that the number of retained historical messages matches the data scale of the current event. Context truncation behavior can be tested by simulating multi-turn dialogue.
  • Check whether the prompt template splices content according to the structured order of fault documents. Model understanding logic can be validated by inputting simulated fault data.
