utilities for block layer IO tracing
Descriptionblktrace is a block layer IO tracing mechanism which provides detailed information about request queue operations up to user space. There are three major components that are provided: blktrace: A utility which transfers event traces from the kernel into either long-term on-disk storage, or provides direct formatted output (via blkparse). blkparse: A utility which formats events stored in files, or when run in live mode directly outputs data collected by blktrace. iowatcher: A utility to visualize block I/O patterns. It generates graphs from blktrace runs to help visualize IO patterns and performance. It can plot multiple blktrace runs together, making it easy to compare the differences between different benchmark runs.
Upload new screenshots
Thanks for uploading more screenshots. Please note:
- Your screenshot should contain a typical scene when working with it.
- Take only a screenshot of the respective application and not of your whole desktop (unless the screenshot is meant for a window manager).
- Your screenshots must be in PNG format.
- You can upload multiple images at once.
- Your screenshot need to be approved by the moderators first. You will already see your screenshot but it will not be visible to others instantly. If moderators reject your upload you will get notified next time you visit this site (requires cookies).
- Images larger than 800x600 pixels will automatically be reduced. So don't try to capture too much detail in a screenshot. It may become unreadable. Shrink the applications window if possible.
- Screenshots are made public and can freely be used by anyone.
- Useful programs for making screenshots are shutter, ksnapshot (KDE), gimp, xwd or scrot. See the Debian wiki for more information on how to make screenshots under Debian.
- Please set your language to english so that everybody understands it. If you don't use english by default please start your application from a shell using after setting "export LANG=C".
