PYBOOTCHARTGUI(1)					      General Commands Manual						 PYBOOTCHARTGUI(1)

NAME

       pybootchartgui - viewer for boot process performance analysis results

SYNOPSIS

       pybootchartgui [options] files...

DESCRIPTION

       This manual page documents briefly the pybootchartgui command.

       pybootchartgui is a graphical program to view the data recorded by bootchart2.

OPTIONS

       -h, --help
	      Show summary of options.t

       --version
	      Show version of program.

       -i, --interactive
	      Start in active mode

       -f FORMAT, --format=FORMAT
	      Image format

       -o PATH, --output=PATH
	      Output path (file or directory) where charts are stored

       -n, --no-prune
	      Do not prune the process tree

       -q, --quiet
	      Suppress informational messages

       -t, --boot-time
	      Only display the boot time of the boot in text format (stdout)

       --very-quiet
	      Suppress all messages except errors

       --verbose
	      Print all messages

       --profile
	      Profile rendering of chart (only useful when in batch mode indicated by -f)

       --show-pid
	      Show process ids in the bootchart as 'processname [pid]'

       --show-all
	      Show all process information in the bootchart as '/process/path/exe [pid] [args]'

       --crop-after=PROCESS
	      Crop chart when idle after PROCESS is started

       --annotate=PROCESS
	      Annotate	position where PROCESS is started; can be specified multiple times. To create a single annotation when any one of a set of
	      processes is started, use commas to separate the names.

       --annotate-file=FILENAME
	      Filename to write annotation points to.

NAME

       bootchart.conf - Boot performance analysis graphing tool configuration file

SYNOPSIS

       /etc/systemd/bootchart.conf

DESCRIPTION

       When starting, systemd-bootchart will read the configuration file bootchart.conf. This configuration file determines logging parameters and
       graph output.

OPTIONS

       Samples=500
	   Configure the amount of samples to record in total before bootchart exits. Each sample will record at intervals defined by Frequency=.

       Frequency=25
	   Configure the sample log frequency. This can be a fractional number, but must be larger than 0.0. Most systems can cope with values
	   under 25-50 without impacting boot time severely.

       Relative=no
	   Configures whether the left axis of the output graph equals time=0.0 (CLOCK_MONOTONIC start). This is useful for using bootchart at
	   post-boot time to profile an already booted system, otherwise the graph would become extremely large. If set to yes, the horizontal
	   axis starts at the first recorded sample instead of time=0.0.

       Filter=no
	   Configures whether the resulting graph should omit tasks that did not contribute significantly to the boot. Processes that are too
	   short-lived (only seen in one sample) or that do not consume any significant CPU time (less than 0.001sec) will not be displayed in the
	   output graph.

       Output=[path]
	   Configures the output directory for writing the graphs. By default, bootchart writes the graphs to /run/log.

       Init=[path]
	   Configures bootchart to run a non-standard binary instead of /sbin/init. This option is only relevant if bootchart was invoked from the
	   kernel command line with init=/usr/lib/systemd/systemd-bootchart.

       PlotMemoryUsage=no
	   If set to yes, enables logging and graphing of processes' PSS memory consumption.

       PlotEntropyGraph=no
	   If set to yes, enables logging and graphing of the kernel random entropy pool size.

       ScaleX=100
	   Horizontal scaling factor for all variable graph components.

       ScaleY=20
	   Vertical scaling factor for all variable graph components.
