Reported memory usage information includes %MEM (percent of physical memory used), VSZ (total amount of virtual memory used), and RSS (total amount of physical memory used)。你可以使用 “–sort”选项对进程进行排序,例如按RSS进行排序: \$ ps aux --sort -rss 10.smem smem命令允许你统计基于/...
http://opentips.blogspot.com/2008/01/linux-process-memory-usage.html The following shell script is used to monitor the memory usage of a process. Save the following script in a file (for ex, memusage.sh) and run it with the process name you want to monitor. ...
关于ZONE_DEVICE, 具体的信息可以参见[ATCH v2 3/9mm: ZONE_DEVICE for “device memory” While pmem is usable as a block device or via DAX mappings to userspace there are several usage scenarios that can not target pmem due to its lack of struct page coverage. In preparation for “hot plugg...
使用Linux系统的ECS实例时,出现系统卡顿、内部服务响应速度变慢等问题。通过实例健康诊断显示:该实例当前内存的使用率已超过80%。 可能原因 ECS实例中存在异常的进程或服务,占用大量内存,导致内存使用率过高。一般来说,当内存使用率≥80%时,定义为内存使用率过高。建议您通过创建报警规则,实时监控ECS实例的波动情况,具...
Smem – Memory Reporting Tool When a normal user runssmem, it displays memory usage by a process that the user has started, the processes are arranged in order of increasingPSS. Take a look at the output below on my system for memory usage by processes started by the usertecmint: ...
在__memblock_remove()中有提到,memblock_isolate_range()主要作用是将要移除的物理内存区从reserved 内存区中分离出来,将 start_rgn 和 end_rgn(该内存区块的起始、结束索引号)返回回去,而这里,由于我们传入的type 是 memblock.memory,该函数会根据入参 base 和 size 标记节点内存范围,将该内存从 memory 中划分...
