Telegraf
Metric retention period settings
| metrics store | Key Features | Advantages | Cons | Metric retention period settings |
| Prometheus | Time series database, primarily designed for monitoring and alerting | Simple setup and operation, powerful query language (PromQL), and rich community and ecosystem. | Difficult to scale horizontally, inefficient for long-term data storage | simple flag |
| InfluxDB | High-performance time series database, suitable for a variety of use cases | High write and read performance, flexible data retention policy, integration with TICK stack | Complex setup and management, performance may decrease as database size increases | SQL Policy (Database Space Management) |
| Graphite | Time series data collection and graphing tool, primarily used for server monitoring. | Simple structure, scalability, and integration with various visualization tools | High disk I/O usage, complex expansion | Own configuration file (.ini) |
| VictoriaMetrics | High-performance time series database, compatible with Prometheus | High performance and efficiency, low resource usage, easy installation and operation | Relatively little community support, lacks some advanced features | simple flag |
