What This Category's Data Looks Like
Data sources for this category include dynamic environment monitoring systems, access control management systems, UPS monitoring equipment, and video inspection terminals. Updates occur in real time or daily. Daily documents include inspection records, temperature and humidity ledgers, alarm event records, and shift handover logs. Common data fields include device identifiers, status parameters, alarm levels, and collection times. Some parameters have corresponding physical units, such as degrees Celsius for temperature and percentage for humidity.
What Constraints Do These Characteristics Impose on the Database and Operations Link
Data sources for this category are scattered, including multiple independent monitoring systems and inspection terminals. Unified field mapping and format verification must be completed before data is imported to avoid data confusion. The real-time or daily update rhythm requires the database connection pool to adapt to high-frequency write requests, preventing connection exhaustion and data loss. Structured inspection and alarm documents, paired with a small number of associated unstructured resources, require simultaneous optimization of structured indexing and large-field storage strategies. In addition, the high-frequency query demand for abnormal alarm data requires that core query fields be assigned dedicated indexes to support rapid location of fault clues.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
MONGODB_URI | Exclusive MongoDB connection address for dynamic environment monitoring data, including database authentication parameters | Isolate computer room operations business data from other applications to improve data security |
PG_URL | PostgreSQL connection address for structured operations data, configure connection timeout to 30 seconds | Adapt to storage and high-frequency query of structured computer room data such as temperature and humidity, UPS |
DB_MAX_LINK | 800–1200 | Adapt to real-time high-frequency write requests for computer room inspection data, prevent connection pool exhaustion |
REDIS_URL | Local Redis connection address, temporary alarm key expiration time set to 600 seconds | Temporarily cache unacknowledged alarm events in the computer room, avoid long-term occupation of memory resources |
| Database write timeout threshold | 60 seconds | Adapt to batch write scenarios of computer room inspection and alarm data, avoid single write blocking |
| Data cache refresh cycle | Calibrated based on actual measurements | Adapt to update rhythms of inspection data for different computer rooms, balance real-time performance and resource usage |

Three Common Mistakes
- Phenomenon: After deploying FastGPT, slow operation is logged when parsing computer room inspection files, and MongoDB response delay is too high. Cause: No exclusive
MONGODB_URIis configured, and the database connection pool is shared with other applications, causing write requests for computer room operations data to be blocked. - Phenomenon: The dataset.csv exported from computer room inspection data only contains the index field, with no content field. Cause: Structured data mapping rules are not configured correctly, and the content field of inspection records is not bound to the knowledge base content field, leading to missing core data during export.
- Phenomenon: When initiating 1000 concurrent write requests for computer room inspection data, the success rate is low. Cause:
DB_MAX_LINKis set too small, cannot support high-frequency requests from real-time computer room collection, leading to partial connection timeout failures.
How to Confirm the Configuration Is Correct
- Log in to the database configuration page in the FastGPT backend, check the connection addresses and authentication information of
MONGODB_URIandPG_URL, confirm they match the preset computer room operations exclusive configuration. - Initiate a simulated write request for computer room inspection data, check the database logs, confirm there are no connection timeout or write failure errors.
- Export a test csv file of computer room inspection data, check that all expected fields are included, confirm the content field has been generated normally.
- Check the monitoring indicators of Redis cache, confirm that the temporary alarm key expiration time corresponding to
REDIS_URLmeets the configuration requirements, and there is no abnormal memory occupation.
