HPC infrastructure measures dataset - mem table This record contains the mem table of the HPC infrastructure measures dataset. Column descriptions: timestamp: The time at which the measurement was collected. host: The hostname of the node from which the memory statistics were retrieved. committed_as: The amount of memory committed to running processes. mapped: The amount of memory mapped into process address spaces. write_back: The amount of memory currently being flushed to disk. available: The amount of memory immediately available for use without swapping. used_percent: The percentage of physical memory currently in use. huge_pages_free: The number of huge pages currently available. slab: The amount of memory used by kernel data structures managed through the slab allocator. sunreclaim: The portion of slab memory that cannot be reclaimed. swap_total: The total configured swap space. swap_cached: The amount of swapped data that remains cached in memory. available_percent: The percentage of physical memory currently available. high_free: The amount of free memory in the high memory region. huge_page_size: The size of a huge page. huge_pages_total: The total number of huge pages. page_tables: The amount of memory used for process page tables. dirty: The amount of memory containing modified data not yet written to disk. low_total: The total amount of low memory. vmalloc_chunk: The size of the largest available contiguous block in the vmalloc area. used: The amount of memory currently in use. free: The amount of completely unused memory. sreclaimable: The amount of slab memory that can be reclaimed if needed. vmalloc_total: The total size of the vmalloc virtual memory region. total: The total physical memory installed on the system. active: The amount of recently used memory that is less likely to be reclaimed. buffered: The amount of memory used for block device buffering. write_back_tmp: The amount of temporary memory used for write-back operations. cached: The amount of memory used by the filesystem page cache. commit_limit: The upper limit on memory that the system can commit. high_total: The total amount of high memory. inactive: The amount of memory that has not been used recently and that can be reclaimed. low_free: The amount of free low memory. shared: The amount of memory shared across processes. swap_free: The amount of currently unused swap space. vmalloc_used: The amount of vmalloc space currently allocated.HPC基础设施度量数据集 - 内存表 本记录包含HPC基础设施度量数据集的内存表部分。 列说明： timestamp：采集度量数据的时间戳。 host：获取内存统计信息的节点主机名。 committed_as：已提交至运行中进程的内存容量。 mapped：映射至进程地址空间的内存容量。 write_back：当前正刷入磁盘的内存容量。 available：无需交换即可直接使用的可用内存容量。 used_percent：当前物理内存使用率。 huge_pages_free：当前可用大页（huge pages）数量。 slab：通过slab分配器（slab allocator）管理的内核数据结构所占用的内存容量。 sunreclaim：不可回收的slab内存部分。 swap_total：已配置的交换空间总容量。 swap_cached：仍缓存在物理内存中的交换数据量。 available_percent：当前物理内存可用率。 high_free：高端内存区域的空闲内存容量。 huge_page_size：单张大页（huge pages）的大小。 huge_pages_total：大页（huge pages）总数量。 page_tables：进程页表所占用的内存容量。 dirty：包含尚未写入磁盘的已修改数据的内存容量。 low_total：低端内存总容量。 vmalloc_chunk：vmalloc区域中最大的连续可用块大小。 used：当前已使用的内存容量。 free：完全未使用的内存容量。 sreclaimable：必要时可回收的slab内存容量。 vmalloc_total：vmalloc虚拟内存区域总容量。 total：系统安装的物理内存总容量。 active：近期已使用、不易被回收的内存容量。 buffered：用于块设备缓冲的内存容量。 write_back_tmp：用于回写操作的临时内存容量。 cached：文件系统页缓存所占用的内存容量。 commit_limit：系统可提交的内存上限。 high_total：高端内存总容量。 inactive：近期未使用、可被回收的内存容量。 low_free：低端内存的空闲内存容量。 shared：进程间共享的内存容量。 swap_free：当前未使用的交换空间容量。 vmalloc_used：当前已分配的vmalloc空间容量。
