How to get the IO history?

Post by saeed » 2014/11/03 10:31:40

Hello

I know that I can use iotop command to get the list of the current active processes and their I/O. But I would like to know if I can get the past processes, say within the previous day, and their IO. This can help me see what processes have been consuming server memory in a certain point if time.

Thanks in advacne.

Not by default. What you can do is use sar (sysstat) to sample and log the data. You can then query that logged data.
