Re-explain
Data sources are external systems that provide data to Grafana for visualization. They can be added through:
- Web UI: Configuration → Data Sources → Add data source
- Provisioning: Using YAML configuration files
- API: Using Grafana's REST API
Common data sources include:
- Time series databases: Prometheus, InfluxDB, TimescaleDB
- Relational databases: MySQL, PostgreSQL, SQL Server
- Cloud services: AWS CloudWatch, Azure Monitor, Google Cloud Monitoring
- Logging systems: Elasticsearch, Loki
- Application metrics: Graphite, StatsD
Each data source requires specific connection parameters like URL, authentication credentials, and query syntax.
