Bootchart
Bootchart is a tool for performance analysis and visualization
of the Linux boot process. Resource utilization and process
information are collected during the boot process and are later
rendered in a PNG, SVG or EPS encoded chart.
The boot process is modified to start the boot logger
(/sbin/bootchartd)
instead of /sbin/init. The boot logger will run in background and
collect
information from the proc file system (/proc/[PID]/stat, /proc/stat and
/proc/diskstats). The statistics are logged to a virtual memory file
system
(tmpfs). Once the boot process completes (denoted by the existence of
specific processes), the log files are packaged to
/var/log/bootchart.tgz.
The log package can later be processed using a Java application which
builds
the process tree and renders a performance chart. The chart may then be
analyzed to examine process dependency and overall resource
utilization.
A renderer web form is also available on the project web site.
Features include:
- Audit the boot sequence of your computer
- Generate an attractive chart of the processes run,
detailing the time taken, in terms of CPU and I/O
