how to monitor a processes memory usage over time - ubuntu
提问by Joelio
I want to watch a given process in unix over time to see what time memory grows (its a long running job)
我想随着时间的推移在 unix 中观察给定的进程，以查看内存增长的时间（这是一项长期运行的工作）
I guess I could do
我想我能做到
ps -aux | grep PID
and run this from cron every 5 minutes, but it seems there should be a better way.
每 5 分钟从 cron 运行一次，但似乎应该有更好的方法。
Is there a way I can use sar to do this?
有没有办法可以使用 sar 来做到这一点？

I use the following:
我使用以下内容：
$ ps -o rss $(pgrep executablename)
Put that in a while loop or use watch to monitor it over time coupled with tail. You can also tee it to a file and have gnuplot plot it for you and refresh it every few seconds.
把它放在一个 while 循环中或使用 watch 来监视它随着时间的推移加上 tail。您也可以将它发送到一个文件中，并让 gnuplot 为您绘制它并每隔几秒钟刷新一次。
