Hi

I have database server, in which sar showing iostat 80-100% at particular time. so we want to know the particular disk's(fileystem) read/write speed.

I am running iostat -d but it is showing only running state. I want to check last two hours information. is there any way without third party tool.

You can save the output to a file periodically, and analyze it later. Also, you've said previously that you're the administrator of 150 servers...do you not have any monitoring tools in place?
