取进程内存使用量的模块

[mingzym]

对一个进程，监控其内存的使用量，数据从/proc//status里取：

这种模块已经有了 https://github.com/alibaba/tsar/blob/master/modules/mod_proc.c 配置: mod_proc on init 根据pidof init得到的进程id获取具体数据 -bash-3.2$ tsar --proc -l -i 1 Time -----------------------proc--------------------- Time user sys mem RSS read write 26/08/14-18:01:20 0.00 0.00 0.01 608.0K 0.00 0.00 26/08/14-18:01:21 0.00 0.00 0.01 608.0K 0.00 0.00 26/08/14-18:01:22 0.00 0.00 0.01 608.0K 0.00 0.00
