What this category of data looks like
This category of data primarily comes from CMDB, cloud resource inventories, automated discovery tools, and procurement ledgers. It regularly generates four types of documents: configuration item lists, service component relationship topologies, change records, and asset inventory sheets. Data updates follow a daily or weekly schedule. Each data entry includes fields such as configuration item unique identifier, asset type, cross-component dependency relationship, change timestamp, and other fields. There are no unified fixed units. Some fields require association with external system metadata to complete validation.
What constraints do these characteristics impose on the HTTP Interfaces and External Systems link
The data characteristics of this category impose three types of constraints on interface calls. Multiple data sources require interfaces to adapt to the authentication logic of different systems such as CMDB and cloud resource inventories. The fixed daily or weekly update rhythm requires interface requests to match business scheduling windows to avoid repeated calls or missed updated data. The differentiated structure of multiple document types requires flexible field mapping rules to be configured in interface parameters to adapt to the format requirements of different documents such as configuration item lists and relationship topologies. Some fields require association with external metadata, so interfaces must support carrying associated verification parameters to ensure data consistency and alignment between records and actual assets.
How to set configurations
The following configuration items apply to FastGPT v4.17.0.
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
Authorization | Bearer {private system API key} | This category of data comes from private systems such as CMDB. Standard authentication headers are required to complete permission verification |
| Number of documents per single request | 10–15 | Matches the platform's single upload limit to avoid triggering maxLength errors |
variables | Configuration item ID, dependency relationship field | Transmits core business fields of this category to ensure interface return data matches configuration management requirements |
| Timeout period | 300–600 seconds | Adapts to the processing cycle of multi-source data pulling to avoid early request termination |
| Chunked upload size | 800–1200 characters | Adapts to the platform's chunked processing rules to reduce single-transmission load |
responseData | Return only configuration item ID, asset type, change time | Filters redundant fields to reduce interface transmission load and adapt to CMDB data structures |
Three common misconfigurations
- Symptom: A maxLength error is triggered when calling the batch import interface, and the returned content includes a request length limit exceeded prompt. Cause: The number of documents set for a single request exceeds the platform limit, and the reasonable range for single processing of this category is not matched.
- Symptom: A 401 Unauthorized status code is returned when calling an external system interface, and configuration item data cannot be pulled. Cause: The
Authorizationparameter does not carry valid authentication information for the corresponding private system, and the authentication rules for multi-source data are not adapted. - Symptom: The
responseDatareturned by the interface includes a large number of non-core fields, which increases the time spent on configuration item relationship verification. Cause: Return fields are not filtered according to the data structure of this category, and targeted return parameters are not configured.
How to confirm configurations are correctly set
- Initiate a single request test, check whether the fields of the returned data match the configured
responseData, and adjust the return parameters until they match the category data structure. - Simulate a batch request, check whether a maxLength error is triggered, and adjust the number of documents per single request to a reasonable range.
- Verify the validity of the
Authorizationparameter, and confirm that configuration item data from CMDB or cloud resource inventories can be pulled normally. - Check whether the fields transmitted by the
variablesparameter cover the core business fields of the category, and ensure that the interface return data meets configuration management requirements.
