Monitor HDD writes

[oliver@]

Hi,

anyone a nice idea how to monitor which program writes how my bytes to my harddisk over a period of time? I try to find out how much more I could reduce writes to SSD.

[CMD=""]gstat[/CMD]
on the command line

General I/O statistics is not what I was talking about - This I already have set up with SNMP+MRTG. I'm talking about a process-wise analysis. I want to know which process writes stuff to my disk when and how much.

System accounting should do the job.

If the processes run as different users you should see how many I/O ops are made by every single one of them.

I "discovered"
% top -m io -o total -b
This seems to be OK so far for my task.
