sysstat监控工具包使用手册http://sebastien.godard.pagesperso-orange.fr/documentation.html

全部使用手册见：http://sebastien.godard.pagesperso-orange.fr/documentation.html

举个例子，查看某个进程有没有内存泄漏：

 

 

minflt/s

Total number of minor faults the task has made per second, those which have not required loading a memory page from disk.

majflt/s

Total number of major faults the task has made per second, those which have required loading a memory page from disk.

VSZ

Virtual Size: The virtual memory usage of entire task in kilobytes.

RSS

Resident Set Size: The non-swapped physical memory used by the task in kilobytes.

如果VSZ和RSS在随着时间在不断增长，就非常有可能有内存泄漏。
