Pepper Metrics基于RED理论，即对每个服务 （这里的服务特指进程中的某种调用，比如调用一次数据库查询）进行RED指标收集，并持久化到数据库，并通过dashboard进行展示，辅助进行性能趋势分析。

- 对Jedis/JedisCluster操作进行性能收集分析
- 对Http请求进行性能分析
- 对Mybatis的数据库操作进行性能分析
- 对Motan/Dubbo的RPC调用进行性能分析（支持调用方及服务方）
- 对多种时序数据库数据源的支持，目前默认为Prometheus
- 开箱即用的Grafana Dashboard，方便对历史趋势进行分析
- 基于SPI的可扩展架构，非常容易开发插件支持更多的开源组件
