Dialog Logs and Auditing for Gas Revenue Yield

What data for this category looks like

Data related to gas revenue yield comes from four sources: internal operating ledgers of urban gas operation enterprises, listed price announcements from upstream natural gas suppliers, terminal sales price adjustment filing documents, and daily usage statistics from pipeline network operations. Data updates daily to support same-day revenue yield daily report generation. Data uses structured table format, with fields including date, unit gas supply cost, terminal sales unit price, pipeline network operation and maintenance allocated cost, current gas sales volume, current total revenue, current total cost, and revenue yield value. Units include yuan per cubic meter, ten thousand cubic meters, and yuan. No percentage-based statistical statements are used.

What constraints these characteristics impose on dialog logs and auditing

Multi-source data access requires logs to record the source identifier of each data block. This prevents inability to trace data authenticity during audits. Daily update frequency requires logs to be archived by natural day. This facilitates monthly compliance audit checks. Structured fields require audits to verify field completeness. This prevents missing key parameters for revenue yield calculation. Additionally, gas operation data involves pricing compliance. Logs must retain information such as the time range of user queries and the calling role. This meets traceability requirements for regulatory audits.

How to set configurations

Configuration Item	Recommended Setting	Rationale
`UPLOAD_FILE_MAX_SIZE`	`50 MB`	Structured documents for gas revenue yield daily reports typically do not exceed 50 MB per file. This matches daily upload needs and avoids unnecessary resource usage
`PARSE_FILE_TIMEOUT_SECONDS`	`300 seconds`	Structured tables require association of multiple fields to calculate revenue yield. Parsing takes longer than plain text documents. This setting reserves sufficient processing time
`maxContext`	`8000–12000 characters`	Daily gas data includes multi-dimensional fields. Sufficient context is needed to accommodate historical conversations and data details. This supports coherent revenue yield queries
`LOG_RETENTION_DAYS`	`180 days`	Public utility industry audit compliance requirements mandate retaining at least six months of operation logs. This meets regulatory traceability needs
`AUDIT_FIELD_WHITELIST`	`["query_time", "source_data_id", "user_role", "response_status"]`	Only retain core fields required for auditing. This reduces redundant log storage while covering core needs for permission, traceability, and status verification
`ERROR_REPORT_THRESHOLD`	`Calibrated based on actual testing`	Gas data updates at a fixed daily frequency. Adjust the threshold based on actual error scenarios to avoid false positives or false negatives

The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require individual analysis. It is recommended to test on your own samples before finalizing settings.

Three common mistakes

When uploading a gas revenue yield daily report document on the conversation page, a 503 error is prompted, but backend logs show the file was uploaded successfully. The cause is that the UPLOAD_FILE_MAX_SIZE configuration value is smaller than the actual uploaded file size. The frontend did not synchronize updated verification rules, leading to frontend-triggered errors while the backend receives the file normally.
When calling the revenue yield calculation logic in a conversation, a prompt saying "No permission to operate this conversation record" appears. The cause is that the AUDIT_FIELD_WHITELIST does not include the user role verification field. This prevents the permission interception logic from triggering normally.
After upgrading to version 4.9.0, refreshing the conversation page causes historical gas data conversation records to disappear, showing a new conversation instead. The cause is that the default value of maxContext is reset after the upgrade. The system cannot load historical conversation contexts that exceed the default length.

How to confirm configurations are set correctly

Upload a simulated gas revenue yield daily report document. Check that the frontend does not show a 503 error, and that backend parsing logs show fields fully match the whitelist range configured in AUDIT_FIELD_WHITELIST.
Switch to an unauthorized role to initiate a revenue yield query conversation. Check if a permission interception prompt is triggered to verify that the permission verification logic is working.
After upgrading or resetting configurations, refresh the conversation page. Check that historical gas data conversation records load normally to verify that the maxContext configuration was not accidentally reset.
Simulate multiple consecutive document parsing errors. Check if an error alert is triggered to verify that the alert logic for the ERROR_REPORT_THRESHOLD configuration is working.
