<p>add page</p> <p><b>New page</b></p><div>; Summary : Add bootchart boot logger functionality to busybox<br /> <br /> ; Proposer : Tim Bird<br /> <br /> == Description ==<br /> It would be nice to add bootchart functionality to busybox.<br /> Most distributions now have bootchart available as a package, which allows an<br /> administrator to see machine resource usage and process startup times, for<br /> the system bootup. The existing bootchart boot logger, however, is a shell<br /> script, which consumes too much resources when running on an embedded platform.<br /> <br /> The Android system includes bootchart boot logger functionality in it's<br /> 'init' program. It would be nice to include similar boot logging functionality<br /> built into busybox.<br /> <br /> The feature would be to grab information from various /proc files, and save<br /> them into the files expected by bootchart, for a duration specified as a<br /> parameter to the 'init' applet of busybox. The duration parameter could be<br /> passed as an environment variable from the kernel, copied from the kernel<br /> command line, or set in a specially-named file. (Note that the latter<br /> two are used in Android. It would probably be good to keep compatibility<br /> with the Android method of parameter passing, just to avoid confusion.)<br /> <br /> Note that the code for this in Android 'init' is licensed under the Apache<br /> license. It's less than 400 lines of C code.<br /> <br /> The benefit of this is that it would allow easy visualization of embedded system<br /> bootup information.<br /> <br /> == Related work ==<br /> * Bootchart - http://www.bootchart.org/<br /> * Android init and bootchart<br /> ** Usage guide: see http://elinux.org/Using_Bootchart_on_Android<br /> ** Code: see http://android.git.kernel.org/?p=platform/system/core.git;a=blob_plain;f=init/bootchart.c;hb=HEAD<br /> <br /> == Comments ==</div>
