LL_TRACE - Low Level Disk Trace Patch for Linux

Description:

LL_TRACE allows you to record a trace of low level SCSI disk requests from the linux kernel. It reserves a large contiguous buffer when the kernel boots. After loading the module and giving it a block device from /dev the kernel logs every request to that device. The user space utility reads the buffer through the module and logs to a file. Make sure the log file is on a different block device to the one being traced!

This package contains:

• A patch against the 2.4.17 kernel (it may work with other 2.4 kernels)
• A kernel module char driver
• A user space configuration and logging tool
