Data sources and structure for this category
Data sources include Prometheus, Zabbix, cloud monitoring, application logs, and CMDB systems. Update frequency is daily synchronization or after each alert rule change. Daily maintenance documents include monitoring metric lists, alert rule documentation, on-call manuals, and alert change records. Data fields include metric identifiers, threshold ranges, alert trigger conditions, notification link configurations, change record numbers, and more. Thresholds use units such as percentage and response time in milliseconds. This data supports scenarios including alert querying and rule adjustment for operations on-call and internal tickets.
Constraints on deployment and upgrade
Multiple monitoring system data sources require deployment to adapt to access protocols and permission configurations of different monitoring sources, to ensure synchronization of existing alert rules and metric data. Data updates occur daily or after each change. After upgrade, incremental synchronization and full verification must be supported to avoid missing latest alert adjustment records. Daily maintenance documents have complex structures. Deployment must provide bulk import functionality for existing documents to reduce repeated configuration work. Incorrect alert configuration directly impacts fault detection efficiency. Deployment and upgrade must include notification link verification steps to ensure configuration takes effect.
Configuration settings
The following configurations apply to FastGPT v4.17.0:
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
DB_MAX_LINK | 100–200 connections | Adapts to high-frequency query scenarios for monitoring alert configurations, prevents service blocking caused by exhausted connections |
MONGODB_URI | Connection string for dedicated alert data storage instance | Isolates alert data from business data, ensures stability and security of alert queries |
REDIS_URL | Address of persistent cache instance | Caches alert rules and metric snapshots, reduces repeated query pressure on databases |
STORAGE_S3_ENDPOINT | Compliant object storage endpoint | Stores alert change records and historical metric snapshots, meets audit and traceability requirements |
ROOT_KEY | Cryptographically random string, minimum 32 characters | Ensures security of management permissions after deployment, prevents unauthorized access |
FILE_TOKEN_KEY | Random token with validity of at least 7 days | Used for secure import and export of alert documents, avoids data risks caused by token leakage |
Three common configuration errors
- The symptom is a 404 status code returned when calling the alert rule synchronization interface. The cause is incorrect configuration of the vector model access endpoint and authentication information, leading to failed request processing.
- The symptom is internal ticket Q&A response time exceeding 30 seconds. The cause is a low
DB_MAX_LINKvalue, leading to exhausted database connections and queued query requests that block processing. - The symptom is failure to load the vector model in a non-GPU environment. The cause is forced enabling of GPU acceleration configuration, preventing model initialization in a CPU environment.
How to confirm configuration is complete
- Execute a database connection test command to verify that the number of connections configured via
DB_MAX_LINKcan be established normally, with no connection timeout or rejection errors. - Import an existing alert rule document, check that it can be successfully synchronized to the system, and that no fields are missing or have format errors.
- Trigger a test alert, verify that the notification link can correctly push to the configured on-call recipients, with no delays or lost messages.
- Check the object storage logs, confirm that alert change records have been correctly uploaded to the specified
STORAGE_S3_ENDPOINTendpoint, with no failed upload records.
