What data in this category looks like
Data sources for railway and highway yield rate-related data include public reports from the Ministry of Transport's Road Network Monitoring and Emergency Response Center, operation ledgers of railway bureau groups, and the national highway network toll collection system. Two data update schedules apply: full updates for railway trunk line operation data are completed every early morning, while incremental updates for highway toll and traffic data are performed hourly. Each single data document corresponds to the daily operation status of a single operating line. The structure includes fields for line owning entity, line number, daily passenger/cargo turnover, daily revenue, daily operating cost, cumulative revenue, and cumulative operating cost. The corresponding units are person-times/ton, ten thousand yuan, ten thousand yuan, ten thousand yuan, ten thousand yuan, and ten thousand yuan respectively.
What constraints do these characteristics impose on conversation logs and auditing
The multi-timeline nature of data updates requires conversation logs to be stored categorized by update nodes. This prevents mixing real-time highway data with daily railway data, ensuring accurate time-based traceability during audits. Multi-field accounting data requires conversation logs to fully record the queried line range, time interval, and specific returned fields. This prevents data loss or tampering during audits. Operating entity attributes divided by line ownership require audit permissions to be subdivided to the single line dimension. This avoids cross-entity log leaks. The large single return volume of batch data requires log retrieval to support quick filtering by line ID and time range, improving audit efficiency.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
logRetentionDays | 90 days | The standard audit cycle for the railway and highway industry is quarterly. 90 days of log retention covers full audit requirements while balancing storage resource usage |
recallSimilarityThreshold | 0.82–0.88 | Conversation log recall requires matching line IDs and query time ranges. This threshold filters non-target sessions and ensures accuracy of audit recalls |
maxContext | 10 sessions | A single yield rate query associates multiple historical line data points. 10 sessions of context fully displays the query chain and meets audit traceability requirements |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Railway and highway operation data documents typically contain multi-line batch data. A 600-second timeout prevents long document parsing interruptions |
EXPORT_LOG_CRON | 0 2 * * 1 | Weekly industry audits are mostly conducted on Mondays. This Cron expression automatically exports audit logs every Monday early morning |
The parameter values provided on this page are common recommendations used as a starting point for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require specific analysis, and it is recommended to test against your own samples before finalizing settings.
Three Common Misconfigurations
- Symptom: The interface prompts "No permission to operate this conversation record". Cause:
logPermissionScopeis not configured to group by line ownership, causing the permission check logic to fail to match the user's owned operating line log range. - Symptom: After upgrading to version 4.9.0 or above, records disappear after refreshing the front-end conversation page, but background log lists can view them. Cause: The cache path for front-end session storage is not updated synchronously, and session IDs from the old version are not recognized by the new framework.
- Symptom: No historical records appear after opening the login-free window, but corresponding records exist in the background logs. Cause: The
sessionRecallEnabledconfiguration is not enabled in login-free mode, causing the front end to not load session data stored in the background.
How to Verify Configuration is Valid
- Trigger a yield rate query for a specified railway line. Check if the system log fully records the line ID, query time, returned fields, etc., and verify that the log content matches the actual operation.
- Adjust
logRetentionDaysto 30 days. Wait 24 hours, then check the background log list to confirm that old logs older than 30 days have been automatically cleaned, verifying that the retention configuration is effective. - Switch to a test account for a non-authorized operating line. Try to view the corresponding session log, confirm that the interface pops up a permission error prompt, verifying that the permission configuration is effective.
- Manually trigger the scheduled export task. Check if the specified storage path generates an audit log file in the correct format, verifying that the export configuration is effective.
