What the data for this category looks like
Cement yield rate related data mainly comes from domestic building materials industry market platforms, regional bulk cement industry associations, and futures exchange trading floor data. Data updates are completed at fixed daily times to compile full market data for all categories for the day. Each daily report document includes fields such as statistical date, regional coverage, ex-factory average price and wholesale average price for mainstream product labels (such as P.O42.5), daily shipment volume, and inventory turnover days. Units are uniformly yuan/ton, ton, or percentage. Data fields are adjusted based on regional policies and category segmentations. Some regions will additionally mark price difference data between bulk and bagged cement.
What constraints do these characteristics impose on the "conversation logs and auditing" link
The market data for the cement category has a fixed update schedule and relies on same-day compilation results. Conversation logs must fully record the data source timestamp of each query. This prevents expired data from being used during retrospective reviews. The data includes multi-dimensional segmented fields. Logs must accurately retain parameters such as the region and label specified in user queries. This ensures query logic can be reproduced during audits. Data units include yuan/ton, ton, and percentage. Logs must clearly mark the unit corresponding to each value. This avoids confusion about value meanings during audits. Some regions have additional price difference fields. Logs must record whether non-standard field queries were triggered. This ensures audits cover all business scenarios.
How to configure the settings
| Configuration Item | Recommended Value | Rationale for this value |
|---|---|---|
CHAT_LOG_RETENTION_DAYS | 30–90 days | The audit cycle for cement market daily reports usually covers monthly to quarterly periods, and this value range meets compliance traceability requirements |
ENABLE_AUDIT_LOG | Enabled | Scenarios requiring audit compliance need full recording of the full link of conversation operations |
LOG_RECORD_REQUEST_BODY | Enabled | Cement data includes segmented parameters such as region and label, and recording the request body ensures that query logic can be reproduced during audits |
AUDIT_LOG_FIELD_WHITELIST | Includes date, region, label, unit price fields | Focus on the core audit dimensions of cement market data, filter non-essential fields to reduce log storage overhead |
LOG_LEVEL | info | Need to record the full link of request parameters and return results to facilitate troubleshooting and audit retrospective reviews |
The parameter values provided on this page are conventional recommendations used as a starting point for configuration. Actual values are affected by material form, 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 mistakes
- Phenomenon: A
400 Bad Requesterror is returned after calling the cement market API, and no corresponding request record exists in the system logs. Cause: TheLOG_RECORD_REQUEST_BODYconfiguration is not enabled, causing the request to not be logged, making it impossible to troubleshoot parameter errors via logs. - Phenomenon: Conversation logs are automatically lost, and records exceeding the preset retention period cannot be queried. Cause: The conversation log retention days are incorrectly configured, failing to match the audit cycle requirements for cement market data.
- Phenomenon: Audit logs only display values without marked units, making it impossible to distinguish between yuan/ton and percentage data during audits. Cause: The audit log field whitelist is not configured to include unit fields, or the logs do not fully record unit information from the response body.
How to confirm the configuration is correct
- Go to the log management page in the system backend, query cement market query requests initiated on the same day, and verify that complete request parameters such as region and label are included.
- After adjusting the conversation log retention period configuration, verify that conversation logs exceeding the configured period cannot be queried, which meets the time requirements for business audits.
- Trigger a query that includes non-standard price difference fields, and verify that the audit log records the call status of this field.
- View log entries at the corresponding level, confirm that each request includes unit annotation information for the response result.
