What data for this category looks like
Packaging and printing investment research data primarily comes from industry association public reports, raw and auxiliary material supplier quotation systems, printing process standard documents, and customer order specification files.
Data update cadence falls into three categories:
- Raw and auxiliary material unit prices and order scheduling data are updated daily
- Printing process parameters and environmental compliance standards are updated quarterly
- Industry trend analysis reports are updated monthly
Individual documents are structured by process modules, including detailed process parameters for gravure printing, flexography, digital printing, and other categories. Fields include printing accuracy (unit: μm), substrate thickness (unit: mm), order batch (unit: ten thousand sets), environmental compliance grade, and more. There is no unified fixed document length. The longest single core parameter description can exceed one thousand characters.
What constraints do these characteristics impose on conversation logs and auditing
The multi-classification, multi-unit, and multi-update frequency characteristics of packaging and printing investment research data create three core constraints for conversation logs and auditing. First, data types cover multiple dimensions including processes, materials, and compliance. Logs must be stored sharded by type to avoid data overload on single index tables. Second, fields include specific units such as μm, mm, and ten thousand sets. The auditing link must verify that parameter units match business scenarios to prevent invalid calls. Third, update cycles vary widely across different data types. Auditing nodes must distinguish retention periods for real-time updated data and static data to ensure complete compliance auditing. Additionally, single parameter descriptions can be lengthy, so log single-record capacity must accommodate long-text storage requirements.
How to set the configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
logRetentionDays | 180 days | Packaging and printing industry compliance auditing requirements mandate retention of investment research sessions and log data for at least six months |
auditEnable | true | Full tracking of calls for raw and auxiliary material parameters and process parameters is required to meet internal auditing and external compliance requirements |
logShardByDataType | true | Store logs sharded by three categories: process, material, and compliance data, to improve retrieval efficiency and data isolation |
maxLogEntryChars | 2000 characters | Accommodate the length requirements of packaging and printing process parameter descriptions, to avoid truncation of long-text logs |
frontendLogVisibleScope | Calibrated by business scenario | Differentiate log visibility ranges for non-logged-in and authorized users, to match permission requirements for different roles |
fieldValidationRules | Calibrated through actual testing | Verify units and value ranges for fields such as printing accuracy and substrate thickness in logs, to ensure data validity |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material forms, data volume, and business rules. Specific issues require targeted analysis. It is recommended to test on your own samples before finalizing settings.
Three common misconfigurations
- Symptom: An error
cannot read properties of undefined (reading 'logContent')is returned when viewing session log details. Cause: ThelogShardByDataTypeparameter is not configured, leading to incomplete indexing of log fields during cross-shard retrieval. - Symptom: The user identification field in conversation logs is empty, and associated user accounts cannot be linked. Cause: Channel identity mapping configuration is not enabled, and front-end user identification is not written to log fields.
- Symptom: Non-logged-in users cannot view historical conversation records on the front end, but corresponding records can be queried in back-end logs. Cause: The
frontendLogVisibleScopeconfiguration is not adjusted, and only back-end access permissions are enabled.
How to confirm the configuration is complete
- Access the log management backend, randomly retrieve a session log related to packaging and printing processes, and confirm that fields include preset business fields such as printing accuracy and order batch, and that units match the business scenario.
- Trigger an investment research session, check whether the backend logs generate corresponding sharded indexes by data type, and verify the storage logic through log index tags.
- Simulate two login scenarios: non-logged-in and authorized accounts, check whether the front end can normally display corresponding conversation history, and whether back-end logs fully record user identification.
- Trigger batch export of session logs, confirm that the export process has no errors, and that the exported file capacity meets the preset configuration requirements.
