EMT性能数据收集工具

EMT 是一个脚本工具，用来收集和存储性能相关的度量数据，例如 CPU 使用率、内存使用率、IO等。EMT exists to bridge a gap between system and application-specific performance metrics gathering. It provides an easy way to gather common system performance metrics, as well as providing a simple plugin-based interface to collect custom application-specific metrics.
