Linux 内存 metricset
编辑Linux 内存 metricset
编辑此功能处于测试阶段，可能随时更改。其设计和代码不如正式 GA 功能成熟，按原样提供，不提供任何担保。测试版功能不受正式 GA 功能支持 SLA 的约束。
内存 metricset 扩展了 system/memory 并添加了 Linux 特定的内存指标，包括巨页和整体分页统计信息。
目前，此数据是 Metricbeat 中 system/memory 的一部分，但只能在 Fleet 的 Linux 集成中找到。将来，此数据将从 system/memory 中移除。
这是一个默认的 metricset。如果主机模块未配置，则默认启用此 metricset。
有关 metricset 中每个字段的说明，请参阅导出的字段部分。
以下是此 metricset 生成的示例文档
