What the Data for This Category Looks Like
The data related to gas yield rates comes primarily from public interfaces of public utility energy regulators and formal energy trading platforms. It is updated once daily, with the previous calendar day’s daily report data released after market close. Data documents use a structured table format, including fields such as report period, trading target name, daily trading average price, previous trading day average price, and yield change value. Most units are yuan per cubic meter or USD per million British thermal units, with no extra redundant statistical fields. The data only covers publicly traded gas categories, and excludes non-marketized internal settlement data.
Constraints on Tool Calling and Plugins
First, the daily update schedule requires tool calls to strictly align with the data source’s update time. Early calls will retrieve empty or outdated data. Second, the coexistence of multiple units in fields requires plugins to support unit conversion configuration. Without this, cross-data-source numerical calculation errors will occur. Third, the fixed structured field format requires plugins to use precise filter conditions when called. Missing or incorrect filters will return redundant data or fail to match target information. Additionally, public interface access frequency limits require setting reasonable request rates for tool calls. High-frequency calls will trigger interface access blocking.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
plugin_cron_expression | 0 30 20 * * * | Matches the daily 20:00 update time of domestic energy data platforms, ensuring the latest data is available when a call is made |
plugin_api_timeout | 600 seconds | Structured data parsing and interface requests require a certain amount of time, preventing task interruption due to timeout |
plugin_filter_fields | Report Date, Trading Subject, Income Change Value | Only extract core fields required by the workflow, reducing data transmission and parsing overhead |
plugin_unit_conversion | {"yuan_per_cubic_meter": "yuan_per_cubic_meter", "usd_per_million_btu": "0.0264172 yuan_per_cubic_meter"} | Compatibility with unit differences between domestic and international data sources, unifying output to standard units |
plugin_request_rate_limit | 1 time/day | The data source updates only once per day; high-frequency calls will trigger interface access restrictions |
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 on your own samples before finalizing settings.
Three Common Misconfigurations
- Phenomenon: Calling the gas data plugin returns a connection failure, and logs in the Docker deployment environment show
Connection refusedortimeouterrors. Cause: The target API port for plugin calls is not mapped to the host machine network, causing the container to be unable to access external data source interfaces. - Phenomenon: The gas yield rate data fields returned after workflow execution are empty. Cause: The
plugin_filter_fieldsparameter is not configured, or the configured field names do not match those returned by the data source, resulting in parsing failure. - Phenomenon: After the scheduled plugin call is triggered, the returned data is always outdated data from the previous day. Cause: The execution time set in
plugin_cron_expressionis earlier than the actual update time of the data source, and each call retrieves unupdated cached data.
How to Verify Proper Configuration
- Manually trigger plugin execution, and verify that the returned data fields only include the contents in the configured
plugin_filter_fieldslist, with no additional redundant fields. - Check the system logs to confirm that the scheduled task execution time matches the setting of
plugin_cron_expression. - Compare the return values of domestic and international data sources to confirm that the unit conversion rules configured in
plugin_unit_conversiontake effect correctly. - Check the number of plugin call requests to confirm that the limit set in
plugin_request_rate_limitis not exceeded within a single update cycle.
