What this category of data looks like
This category of data comes from monitoring alerts, log platforms, APM tools, and user feedback. The update frequency is real-time or synchronized immediately after each incident occurs. Daily generated documents include fault work orders, incident timelines, emergency plans, and fault notifications. Fields cover incident unique identifiers, affected service scope, occurrence and recovery times, root cause analysis results, number of affected users, and more. There are no fixed statistical units; records and updates are made on a per-incident basis.
What constraints these characteristics impose on the deployment and upgrade link
This category of data is multi-sourced and updated in real time, and must be persisted for subsequent retrospectives. As such, the deployment phase must ensure stable database connections to prevent event data loss from connection interruptions. Additionally, single-incident documents contain multi-field structured records, so sufficient storage capacity and reasonable connection parameters must be configured. The timeliness of fault response requires that post-deployment service availability meets standards. The upgrade phase must support zero-downtime or rolling updates to avoid disrupting active incident work orders. If containerized deployment is used, persistent storage volumes must be configured to prevent database data corruption from abnormal events such as power outages.
How to Set Configurations
These configurations apply to FastGPT v4.17.0.
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
DB_MAX_LINK | 10-20 connections | Adapts to the concurrency requirements of real-time writing from multiple data sources, avoiding data write failures caused by exhausted connections |
MONGODB_URI | mongodb://user:pass@host:port/dbname?authSource=admin | Stores unstructured data such as incident timelines and fault notifications; authentication information must be configured to ensure data security |
PG_URL | postgresql://user:pass@host:port/dbname?sslmode=require | Stores structured business data such as fault work orders and emergency plans; SSL mode ensures transmission security |
REDIS_URL | redis://:pass@host:port/0 | Caches real-time alerts and user feedback data to reduce database query pressure |
ROOT_KEY | A randomly generated 32-character string | Configures the system administrator permission key to ensure the security of background operations |
STORAGE_S3_ENDPOINT | Fill in according to the actual storage service address | Stores attachments such as logs and screenshots related to faults, adapting to multi-environment storage requirements |
Three Common Misconfigurations
- Symptom: After containerized deployment, a power outage and restart causes PostgreSQL or MongoDB services to fail to start. Logs display connection refused or data file corruption errors. Cause: No persistent storage volume was configured. Data within the container is lost when the container is destroyed, so original business data cannot be read after restart.
- Symptom: New users cannot register after deployment via Docker Compose, with no obvious error messages in the background. Cause: The public registration switch is not configured, or user permission-related parameters are not correctly set, blocking the new user registration process.
- Symptom: Third-party model key configuration fails to enable normal calls. The chat interface returns empty results or a 403 status code. Cause: Environment variables for the model key are not correctly configured, or the key has insufficient permissions, failing model interface call verification.
How to Verify a Correct Configuration
- Execute the container startup command, review service logs for database connection-related error messages, and confirm there are no connection failure or authentication failure alerts.
- Attempt to create a test fault work order, fill in all required fields, and submit. Confirm that data is successfully written to the database and can be queried in the background.
- After configuring the third-party model key, initiate a test chat. Confirm that the interface returns normal response content, with no permission or connection timeout errors.
- Simulate a power outage and restart scenario, verify that the database service starts normally after the container restarts, and that original fault work order data is not lost.
