HD Monitoring

Jadedkill · 08-11-2011, 08:24 AM

I would like to have some suggestions on HD monitoring software for Linux systems. Not the typical SMART monitoring though. Looking for more of a 'write' tracking software for the hard disks on mail servers. I have had issues with my mail servers HD becoming full in a matter of 24 hours on multiple occasions. This type of software will help me correspond times with what is being written and saved to the HD. Thanks in advance.

Take a look at 'man iostat'. For example:

Code:

iostat -t -x /dev/md1 5 &>iostat.log &

Thanks for your quick response. I was unsure if there was a built in utility to do this or not. I will check this upon my return home this evening.

Depends what you want to know.
If per process, I suggest you look at collectl - will tell you I/O rates if taskstats is enabled in the kernel. If per I/O per device maybe blktrace - pretty heavyweight though. More a diagnostic.
