BOOTCHART(1)						      General Commands Manual						      BOOTCHART(1)

NAME

       bootchart - render a chart from the statistical data recorded with bootchartd

SYNOPSIS

       bootchart [-f|--format FORMAT] [-n|--no-prune] [-o|--output-dir DIR] files ...

DESCRIPTION

       bootchart  is used to process the log file created by bootchartd(1) (/var/log/bootchart.tgz by default).  bootchart builds the process tree
       and renders a performance chart in different formats.  The chart may then be analyzed to examine process dependency  and  overall  resource
       utilization.

OPTIONS

       -f,--format FORMAT
	      Sets the format of the image. Possible values are: png, eps, svg (default)

       -h, --help
	      Display brief usage message.

       -n, --no-prune
	      Do  not prune the process tree.  To make the resulting process tree more comprehensible, bootchart will prune the tree using various
	      techniques (removing short-lived processes, merging processes, etc.).  This option disables such behavior.

       -o, --output-dir DIR
	      Sets the output directory for the resulting image. (default: .)

       -v, --version
	      Show program version.

FILES

       /var/log/bootchart.tgz
	      the default log file to parse (unless otherwise specified).

BOOTCHARTD(1)						      General Commands Manual						     BOOTCHARTD(1)

NAME

       bootchartd - collects process information, CPU statistics and disk usage statistics

SYNOPSIS

       bootchartd [start|stop] [bootchart_init=INIT]

DESCRIPTION

       bootchartd  collects  process  information, CPU statistics and disk usage statistics from the /proc/ file system.  The accumulated log file
       may later be visualized using bootchart(1).

       bootchartd is commonly used to profile the boot process for the purpose of speeding it up.  In this case, it is started by  the	kernel	as
       the  init  process.  This is configured by adding the init=/sbin/bootchartd option to the kernel command line -- either interactively or by
       editing the bootloader's configuration file. Please refer to the documentation of your bootloader for details (e.g. lilo, grub or yaboot).

       After bootchartd is initialized during the boot process, it will start the default init process (/sbin/init) to proceed	with  the  regular
       bootup.	If, however, an alternative init process is used (e.g. (/sbin/initng), that process may be specified using the bootchart_init=INIT
       kernel command line parameter.

       Another possibility for using bootchartd is monitoring the resource usage of a specific application or the running system in  general.	In
       this case, bootchartd is started interactively by running bootchartd start and stopped using bootchartd stop.

FILES

       /var/log/bootchartd.tgz
	      default output file

       /etc/bootchartd.conf
	      default configuration file
