What data for this category looks like
Data for this category primarily comes from database monitoring systems, operation audit logs, SQL execution plan files, and operations ticket systems. Daily produced documents include database change orders, slow query performance reports, backup verification records, and permission application approval forms. Data updates are triggered by database changes or synced on a daily basis. Individual records contain fields such as instance ID, operation time, execution duration, permission scope, and backup path. Some fields use standardized units including timestamps, bytes, and request counts.
What constraints these characteristics impose on the database and operations link
Decentralized data sources require integrating collection logic across multiple systems, and adaptation to monitoring metrics and log entries in different formats. Updates triggered by changes or on a daily basis require summary tasks in the operations link to align with change windows and scheduled scheduling cycles. Field differences across multiple document types require the summary process to define unified mapping rules to avoid missing fields or format conflicts. The sensitivity of permission-related data requires strict isolation of unauthorized access during the summary link, while retaining necessary fields for audit tracing. Correlation analysis of slow queries and change records requires matching instance IDs and timestamps to ensure accuracy of data association.
How to configure settings
These configuration items apply to FastGPT v4.17.0
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
MONGODB_URI | Full connection string containing authentication information and replica set identifier | Used to connect to the MongoDB instance storing FastGPT data, ensuring read/write permissions and cluster connectivity |
PG_URL | Connection address configured for a dedicated operations database, enable SSL encryption | Used to store structured data of summarized release notes and operation reports, ensuring transmission security |
DB_MAX_LINK | 10–20 | Limits the database connection pool size to avoid exhausting resources on a single node, adapting to standard single-node deployment specifications |
REDIS_URL | Connection address configured for a local cache instance, set connection timeout to 30 seconds | Used to cache summarized data from high-frequency queries, reducing repeated database access pressure |
| Scheduled task scheduling interval | Triggered by changes or once per day | Aligns with data update frequency, avoiding frequent pulling of redundant data |
Three Common Misconfigurations
- Symptom: Database connection error with prompt
connection refused, unable to pull monitoring data. Cause: The host address and port ofMONGODB_URIare not configured correctly, or the network mode between the Docker container and the target database is not set properly, preventing FastGPT from accessing the target instance. - Symptom: The database connection structure output by the data source plugin cannot be converted to the expected SQL execution results. Cause: Format conversion rules for the data source plugin are not configured, causing the summary process to fail to recognize non-standard connection structures and complete data extraction.
- Symptom: Concurrent requests in single-node deployment cause database connections to be exhausted, making the service unresponsive. Cause: The number of connections for
DB_MAX_LINKis not limited, exceeding the carrying limit of the current hardware specification, leading to connection pool overflow.
How to Verify Correct Configuration
- Execute the database connection test script to verify connectivity of
MONGODB_URIandPG_URL, confirming there are no authentication or network errors. - Trigger a manual summary task to check if the generated release notes and operation reports include expected document entries such as change orders and slow SQL reports.
- View the database connection pool monitoring panel to confirm the current number of connections does not exceed the
DB_MAX_LINKconfiguration limit. - Check the scheduled task logs to confirm that daily or change-triggered summary processes have no timeout or execution failure records.
