Hi all, I am new to Lustre. I recently run some experiment on the clusters machine with lustre backbone and I want to measure the disk IO during the program execution. The problem with using tools like iostat is it just measure the read/write operation in the local disk. Is there any tools for lustre client that I can measure the disk IO not just in my compute node but also to the other machine, how much it is doing read/write operation to all other disk during the execution time. Thanks Regards, Hendra -------------- next part -------------- An HTML attachment was scrubbed... URL: http://lists.lustre.org/pipermail/lustre-discuss/attachments/20091007/78cb6945/attachment.html
