analyze disk performance
Hi. I need to analyze i/o performance on san.
Does there exist any good,free Linux tool to create different load to disk, similar to iometer for Windows?
Does there exist any good, free disk performance tools for Linux working on a higher level than proc/iostat? Preferrably with possibility to log to file and extract data afterwards.
Graphical interface doesn't hurt, but is no must.
Today I use a combination of dd, perls I/O handling procedures and iostat, but it is very cumbersome and difficult to log and create usefull reports.
