What Data Looks Like for This Category
Relevant data for CDN and edge acceleration configuration typically comes from CDN consoles, DNS resolution records, user access logs, and node monitoring alerts. Update frequency is either daily or real-time when configuration changes are made. Daily support documents include domain access forms, cache rule configuration tables, refresh and preheating operation records, and node fault analysis reports. Data fields include node IP, cache effective duration, peak access bandwidth, faulty node ID, and similar items. Only conventional business operation and maintenance record formats are required; no additional mandatory fields are enforced.
Constraints Imposed on Multi-turn Dialogue and Prompt Engineering
Data sources for CDN and edge acceleration configuration are scattered and tied to business operation and maintenance workflows. Multi-turn dialogue must bind chatId to associate a customer’s exclusive domain configuration history, preventing cross-customer context confusion. Data updates take effect in real time alongside configuration changes, so prompts must support dynamic pulling of the latest cache rules and node status to ensure Q&A content matches the currently active configuration. Daily documents are split into three categories: access, cache, and fault handling. Prompts must call preset fields based on scenario: for example, pre-sales scenarios use the filing status field from domain access forms, while after-sales scenarios use node anomaly records from fault analysis reports.
How to Set Configurations
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
chatId | Bind session ID to customer’s exclusive domain | Prevent cross-customer configuration context confusion, match the multi-tenant business scenario of CDN, FastGPT v4.17.0 |
messages | Retain the last 10 rounds of dialogue context | Cover common multi-turn interaction scenarios for cache rule debugging and fault troubleshooting, avoid response delays caused by overly long context |
variables | Inject current domain’s cache TTL (300–86400 seconds), node IP range | Based on standard fields in CDN configuration documents, allow prompts to directly call business-specific data |
| Maximum context length | 8000–12000 characters | Adapt to multi-turn configuration explanations for domain access and cache rules, avoid truncation of critical parameters |
| Single search limit | Top 3 access log records | Match conventional troubleshooting dimensions of CDN access logs, narrow the scope of anomaly troubleshooting |
| Question classification trigger | Preset rules by business scenario | Split dialogue flow into three categories: domain access, cache debugging, fault troubleshooting, adapt to typical CDN business links |
Three Common Misconfigurations
- Phenomenon: After enabling image recognition configuration, the AI indicates it cannot provide image content after an image is uploaded. Cause: The image parsing permission for the multimodal model is not enabled in the dialogue node, or context parameters that support image input are not configured.
- Phenomenon: AI replies automatically attach quoted document links or content, and this display logic cannot be disabled. Cause: The "Quote File Display" switch in the dialogue configuration is not turned off, or the prompt does not explicitly require hiding quoted content.
- Phenomenon: Context loss or response errors occur after multi-turn dialogue exceeds the set number of rounds. Cause: The context retention limit for
messagesis not correctly configured, or non-critical dialogue history is not trimmed according to CDN business scenarios.
How to Confirm Successful Configuration
- Initiate a dialogue containing domain configuration parameters, verify that the AI reply correctly calls the preset
variablesfield content. - Initiate a multi-turn cache rule debugging dialogue, verify that
chatIdremains bound and no cross-customer error information appears in the context. - Upload a test cache rule document, verify that the AI can correctly identify and associate the configuration context of the current session.
- Turn off the "Quote File Display" switch and initiate a dialogue, confirm that no additional document quoted content is included in the reply.
